Background. Paracetamol and non-steroidal anti-inflammatory drugs (NSAIDs) are widely used treatments for mild to moderate pain and fever in pediatric patients. Notwithstanding, greater caution and awareness of their distinct safety profiles is warranted, especially in children with comorbidities. Expert opinion. Herein, expert opinion is presented on the use of these drugs in this setting. Paracetamol is suggested as first-line treatment for managing fever in pediatric patients. For pain, paracetamol is suggested for acute mild-to-moderate pain, whereas NSAIDs are preferred for pain associated with inflammatory conditions. A fixed-dose combination of paracetamol and ibuprofen may be considered for moderate pain, which allows effective analgesia while potentially reducing the risk of adverse events associated with monotherapy. Based on opinion and clinical experience, suggestions were made for pediatric patients considering a large variety of comorbidities. For example, in patients with infection/influenza, the panel concluded that paracetamol should be preferred over NSAIDs. In pediatric patients with inflammatory bowel disease, it was suggested to avoid long-term or high-dose NSAID treatment, particularly in those with active disease. In the presence of skin and soft tissue infections, it was suggested to limit the use of NSAIDs and prioritize paracetamol as first-line therapy. It was also recommended to exercise caution when using NSAIDs in pediatric patients with diabetes. Lastly, shared therapeutic flowcharts were developed that facilitate the patient journey of pediatric patients with comorbidity and fever or pain, which may help promote therapeutic appropriateness and reduce the risk of adverse events, providing practical guidance for general practitioners and pediatricians.
Angiotensin-converting enzyme (ACE) inhibitors (ACEis) are one of the most successful drug classes for the treatment of hypertension and the prevention of its cardiovascular complications. ACE activates the pressor hormone angiotensin but also inactivates the vasodilator peptide bradykinin (BK). A rare side effect of ACEis, angioedema (AE), has been proposed to result from pro-inflammatory effects of BK. Novel considerations are offered in this debate: (1) the bradykinin B2 receptor antagonist icatibant has had an inconsistent effect on ACEi-associated AE, but its potency and duration of action are much inferior to those of a novel nonpeptide antagonist of this receptor, deucrictibant. (2) Tissue kallikrein (KLK-1) is an effective kininogenase, particularly abundant in the salivary glands, possibly related to orofacial presentation of ACEi-induced AE. (3) The strongly regulated human kinin B1 receptor, optimally responsive to Lys-des-Arg9-BK, is functionally compartmentalized with KLK-1 which produces Lys-BK from kininogens. Chronic treatment with ACEi drugs in laboratory animals induces the expression of vascular B1R that mediates vasodilation. Therefore, ACEi-AE may be largely or completely initiated by KLK-1. Inhibitors of this protease or combined antagonists of both kinin receptor subtypes may be useful for the management of this condition.
Background/Objectives: Multidrug-resistant (MDR) Enterobacter spp. are critical pathogens within the ESKAPE group, frequently exhibiting resistance to carbapenems. Antimicrobial photodynamic therapy (aPDT) represents a promising non-antibiotic strategy to circumvent these resistance mechanisms. This scoping review aims to map the current evidence regarding the efficacy of aPDT in inactivating Enterobacter spp., identifying the most effective photosensitizers (PS), light parameters, and existing research gaps. Methods: A systematic search was performed across PubMed, Scopus, and Google Scholar (2013–2025) following PRISMA-ScR guidelines and registered on OSF. Studies were included if they evaluated aPDT against Enterobacter spp. (in vitro or in vivo) and provided quantitative data on microbial reduction. Data was extracted using a standardized charting form covering bacterial strains, PS type, light source, and viability reduction. The results from the eligible sources of evidence were synthesized narratively to address the review objectives. Results: Despite the clinical priority of Enterobacter, only seven studies met the eligibility criteria. Methylene Blue remains the most frequently studied PS, achieving reductions of 3–8 log10. Emerging evidence highlights the synergistic efficacy of monocationic chlorins and graphene-based nanomaterials in enhancing the bactericidal effect of light-based treatments. Notably, aPDT demonstrated the ability to inactivate carbapenemases, the bacterial enzymes responsible for carbapenem resistance. However, only two studies evaluated in vivo applications, primarily within dental settings. Conclusions: aPDT is a promising method against MDR Enterobacter spp. and bypasses traditional resistance mechanisms. However, the limited number of studies indicates a significant knowledge gap. Future research should focus on standardized in vivo protocols and the synergy between aPDT and conventional antibiotics to support clinical translation.
Background/Objectives: Achillea millefolium is a well-known plant used in traditional medicine for the treatment of inflammation, gastrointestinal disorders, respiratory diseases, hypertension, and diabetes, among others. These effects are attributed to the metabolite content of flavonoids and terpenes such as achillin (1) and leucodin (2). Thus, the current investigation aims to standardize the extracts from A. millefollium based on the presence of 1 and 2 and relate them to their relaxant effect in ex vivo assays. Methods: A validated High-Performance Liquid Chromatography (HPLC) method was used to determine the concentration of the main compounds, employing standard molecules previously isolated from the same species and characterized by nuclear magnetic resonance (NMR) and X-ray diffraction. Also, the relaxant effects of both compounds and their combinations were assayed on aortic and tracheal rat rings in an organ bath. Results: Compounds (1) and (2) are the main compounds in hexane, dichloromethane, and hydroalcoholic extracts, present in different proportions. The relaxant effects in ex vivo models of the aorta and trachea showed that the sesquiterpene lactones achillin (1) [Trachea, maximum effect (Emax): 67.67 ± 5.01%, medium effective concentration (EC50): 304.44 ± 2.61 µM; Aorta: Emax: 63.94 ± 6.28%, EC50: 225.73 ± 4.49 µM)] and leucodin (2) (Trachea: Emax: 76.71 ± 4.73%, EC50: 266.40 ± 2.05 µM; Aorta, Emax: 72.96 ± 1.73%, EC50: 163.29 ± 2.99 µM) are responsible for the relaxant effects shown by the extracts. The observed effect is proportional to the concentration of these molecules, with hexane extracts being more active. Additionally, we demonstrate the safety of molecules 1 and 2 through toxicological studies recommended by the OECD. Conclusions: The isolated compounds achillin and leucodin are the primary constituents in the flowers of A. millefolium, with higher concentrations found in hexane extracts, particularly of achillin, which shows a correlation of 2.33 with respect to leucodin. This correlation is closely related to their relaxant effect, as these compounds are the main contributors to the relaxant response in the trachea and aorta, being more effective when used together.
Background/Objectives: Upper respiratory tract infections (URTIs), including common cold and influenza, remain a major global health burden, and their symptomatic management often includes the use of herbal medicines alongside conventional therapies. The aim of this study was to evaluate the real-world use of herbal medicines as drug candidates in the management of URTIs in Estonia, with a focus on differences between pharmacy customers and pharmacy professionals. Methods: A cross-sectional survey was conducted among 905 participants, including 400 pharmacy customers and 505 pharmacy professionals (pharmacists and pharmacy assistants). Standardized questionnaires were used to assess the frequency of use, perceived effectiveness, and safety considerations of commonly used herbal substances and home remedies in adults and children. Results: Herbal medicines and home remedies were widely used, reported by 68% (95% CI: 63.4–72.6%) of pharmacy customers and 71% (95% CI: 67.0–75.0%) of pharmacy professionals. The most commonly used herbal substances included lemon (79%), ginger (57%), garlic (56%), raspberry (55%), and chamomile (50%). While most respondents perceived these remedies as effective for symptom relief, notable discrepancies were observed between customer and professional assessments of efficacy. The use of several herbal substances in children did not consistently align with European Medicines Agency recommendations, highlighting potential safety concerns. The findings demonstrate that widely used herbal substances represent real-world candidates for supportive URTI management; however, their perceived effectiveness and patterns of use are not always supported by regulatory guidance or clinical evidence. These results underscore the need for further pharmacological and clinical studies, as well as improved evidence-based communication between healthcare professionals and patients. Conclusions: The results allow the identification and prioritization of herbal substances as real-world drug candidates for further pharmacological and clinical development.
Background/Objectives: Oral cancer remains a major global health challenge, with persistent limitations in treatment efficacy and significant therapy-related morbidity. Probiotics, owing to their immunomodulatory, anti-inflammatory, and microbiota-regulating properties, have emerged as potential therapeutic and adjuvant agents. This scoping review aimed to systematically map and critically appraise preclinical and clinical evidence regarding the therapeutic and supportive effects of probiotics in oral cancer. Methods: A comprehensive literature search was conducted across PubMed, Scopus, Web of Science, and Google Scholar without temporal restrictions, including studies published up to February 2026. Eligible studies comprised in vitro, in vivo, and clinical investigations evaluating the effects of live or non-viable probiotic interventions on oral cancer biology and related clinical outcomes. Results: Twenty-one studies were included: 13 in vitro, 3 in vivo, and 6 clinical studies. Preclinical evidence indicates that strains such as Lactiplantibacillus plantarum, Lactobacillus acidophilus, and Lacticaseibacillus paracasei exert selective antiproliferative effects (up to 85% inhibition) via apoptosis induction, modulation of PTEN/MAPK and NF-κB signaling, and reduction in pro-inflammatory mediators. In vivo models demonstrated tumor growth suppression and improved survival without significant toxicity. Clinically, probiotics reduced treatment-induced oral mucositis, improved salivary function, and enhanced microbiota stability and patient-reported outcomes. However, evidence on direct oncological endpoints remains limited. Conclusions: Probiotics demonstrate biologically plausible, strain-specific antitumor and supportive effects, with the strongest evidence supporting their role as adjunctive agents, particularly in managing treatment-related complications. Further well-designed in vivo and clinical studies are required to define optimal strains, dosing strategies, and integration with standard oncologic treatments.
Background/Objectives: A matrix system for topical application was developed for a hydrophobic drug model, benzoyl peroxide (BPO), by turning it into its amorphous state to increase its bioavailability. BPO is commonly used to treat acne vulgaris; however, the commercially available products possess several drawbacks including poor absorption due to large crystal size and thus reduced efficacy and skin irritation. Methods: Several polymeric films containing amorphous BPO were successfully prepared for the first time from polymer + plasticizer colloidal dispersions and characterized. Results: The loaded BPO maintained its amorphous state even after 24 months of storage at 5 °C, and drug release could be modulated by adjusting the film compositions. The prepared films were obtained by solvent evaporation, and residual acetone remained below the level of quantification of the analytical method. In addition, the films were thin, flexible, transparent, bioadhesive, and able to remain on the skin for a clinically relevant period. Microscopic imaging confirmed a homogeneous and continuous morphology. Conclusions: The developed formulations may represent promising alternatives for the treatment of acne vulgaris.
One of the most pressing challenges facing healthcare today is the rise of biofilm infections and antibiotic-resistant bacteria, which demand entirely new therapeutic strategies beyond conventional antibiotic reliance. A biofilm is a structured community of microorganisms encased in a self-produced extracellular polymeric substance (EPS) matrix, which confers resistance to host immune defenses and antimicrobial agents. Accumulating evidence demonstrates that plant-derived secondary metabolites—including flavonoids, phenolic acids, tannins, terpenoids, and alkaloids—exert potent antibacterial and antibiofilm activities through diverse mechanisms of action. These natural compounds inhibit biofilm formation by disrupting bacterial adhesion, suppressing quorum sensing, degrading the EPS matrix, and impairing bacterial motility. Beyond independent bioactivity, phytochemicals demonstrate significant synergistic potential when combined with conventional antibiotics, revitalizing antimicrobial efficacy against drug-resistant pathogens. Nanoformulation and biogenic carrier technologies further enhance the bioavailability and therapeutic potency of these compounds. Despite these advances, critical challenges persist, including poor bioavailability, physicochemical instability, dose-dependent toxicity, and the risk of resistance development. This review presents a critical and integrative analysis of the pharmacological mechanisms of plant secondary metabolites, with particular emphasis on their role in combating biofilm-associated infections and antibiotic resistance, and discusses translational opportunities including structure–activity relationship (SAR)-guided optimization, high-throughput screening platforms, and advanced drug delivery systems. Collectively, plant secondary metabolites represent a scientifically compelling and clinically relevant pipeline for the development of next-generation antimicrobial and antibiofilm therapeutics.
Background/Objectives: Curcumin derivatives have attracted interest due to their redox-modulating properties and potential applications in aquatic organisms, yet their molecular interactions and environmental safety remain insufficiently characterized. This study aimed to evaluate the redox-related molecular behavior and ecotoxicological profile of curcumin derivatives, with emphasis on their interaction with glutathione S-transferase from L. vannamei. Methods: Molecular docking and molecular dynamics simulations were performed to assess binding stability and interaction patterns between the derivatives and LvGSTmu. In parallel, computational predictions were used to estimate environmental persistence, bioaccumulation (BCF/BAF), and acute and chronic aquatic toxicity across multiple trophic levels. Results: Docking and dynamics analyses indicated stable ligand–protein interactions, particularly for CURNO, which showed favorable binding behavior without destabilizing the protein structure. Ecotoxicological predictions suggested low bioaccumulation potential and limited persistence for most derivatives, with CURH and CURNO showing higher sediment persistence. Toxicity responses varied by organism and exposure time but did not differ significantly among derivatives relative to curcumin. Conclusions: The derivatives retained redox-related molecular features while presenting an overall acceptable predicted environmental profile. CURNO emerged as a promising candidate, although its environmental behavior supports the need for further monitoring and experimental validation.
Background: Diabetes mellitus is a metabolic disturbance characterized by chronic hyperglycemia, which stems from defective secretion and/or action of insulin. D-Limonene has been studied for the confirmation of its antidiabetic and antioxidant effects. This paper aims to investigate the antidiabetic and antioxidants effects of D-Limonene in an experimental model of DM1. Methods: Female Wistar rats (180–250g) received streptozotocin (STZ, 45 mg/kg) intraperitoneally. Animals with capillary glycemia ≥ 250 mg/dL were considered diabetic. D-Limonene at oral doses of 12.5 mg/kg, 25 mg/kg and 50 mg/kg was administered during 28-day treatment. Water and food intake, weight gain and capillary glycemia were evaluated. At the end of the treatment, the following biochemical parameters were assessed: serum glucose, HbA1c, urea, creatinine, AST, ALT, GGT, ALP and albumin. The oxidative stress markers were determined in plasma, erythrocytes, and aortic homogenates: malondialdehyde, nitrite, myeloperoxidase, superoxide dismutase and catalase. Results: D-Limonene (25 and 50 mg/kg) significantly reduced serum glucose, HbA1c, AST, ALT, GGT and ALP when compared to DC, as well as plasma MDA and nitrite concentrations. Interestingly, D-Limonene (25 and 50 mg/kg) decreased both plasma and aortic myeloperoxidase activities, as well as increased both erythrocytic and aortic catalase activities. Conclusions: These findings, besides a marked D-Limonene-induced hypoglycemic effect, pave the way for further studies comprising a multi-target treatment by providing benefits on hepatic and vascular complications related to the diabetic condition.
Background/Objectives: Course-based Undergraduate Research Experiences (CUREs) represent a form of student crowdsourcing in which individuals perform authentic discovery-based research in a class setting with interest to outside stakeholders. Here, the renowned Tiny Earth (TE) CURE is being utilized to teach microbiology and perform natural product discovery research by students in the course. Methods: In our TE CURE, students collect soil samples from their hometown and characterize bacteria that can inhibit plant and animal pathogens. This unique growing collection of isolates from across Ohio has provided opportunities to facilitate drug discovery and establish biotechnology collaborations. Results: In this study, we describe two outcomes using our environmental strain collection that initiated biotechnology collaborations and identified bacterial candidates for drug discovery. Results from one project led to a partnership with an aquaculture company. A novel biosynthetic gene cluster involved in antagonistic activity was identified, whose product inhibits Aeromonas pathogens, which cause disease in freshwater fish. The other project involves a collaboration with a global commercial cleaning and equipment company to identify lipase activity among Bacillus strains for its potential use in bioremediation. Conclusions: The unique strain collection generated by students in the CURE led to collaboration with biotechnology companies, which contributed to natural product discovery of an antimicrobial product and active enzymatic activity, all of which benefit education and scientific discovery.
Obesity is a growing public health concern linked to poor dietary habits, physical inactivity, and metabolic disturbances, which can be evaluated using complementary laboratory tests. Among pharmacological interventions, semaglutide, a GLP-1 receptor agonist, has shown promise by acting on the central nervous system to reduce appetite and stimulate insulin secretion, thereby improving the lipid profile and reducing inflammation biomarkers. This review focused on changes in lipid parameters and C-reactive protein (CRP) levels in overweight or obese individuals treated with semaglutide, based on phase 3 studies from the STEP program (“Semaglutide Treatment Effect in People with Obesity”). The STEP clinical trial program was conducted across 36 countries, reflecting a broad and diverse geographic representation. Key findings include significant reductions between placebo vs. semaglutide in body weight (−1.3 vs. −13.0 Kg), body mass index (−0.69 vs. −4.72 kg/m2), and waist circumference (−2.79 × −11.81 cm). Additionally, there were notable decreases in triglycerides (−0.67 vs. −20.89%), VLDL-C (−0.99 vs. 20.82%), and CRP levels (−15.45 vs. −55.55%). These changes reflect improvements in both inflammatory and metabolic markers. The observed benefits suggest that semaglutide may contribute to reducing comorbidities associated with metabolic syndrome and to the prevention of cardiovascular disease. Current evidence also supports its potential role in individualized treatment strategies based on patients’ clinical and biochemical profiles. However, despite these promising findings, further long-term studies are required to confirm the efficacy and safety of semaglutide across diverse populations.
Background/Objectives: Vasomotor symptoms (hot flashes) affect 70–80% of menopausal women, significantly impairing quality of life. Current treatments include hormone therapy, which is contraindicated for many patients, and non-hormonal alternatives with limited efficacy or adverse effects. Cannabidiol (CBD), a non-psychoactive phytocannabinoid, has emerged as a potential therapeutic candidate due to its interaction with the endocannabinoid system. This study aimed to investigate whether a standardized Cannabis sativa extract containing isolated CBD attenuates heat dissipation in ovariectomized rats, a preclinical model of estrogen deficiency. Methods: Female Wistar rats were randomly assigned to sham-operated vehicle-treated (SHAM-V), ovariectomized vehicle-treated (OVX-V), or ovariectomized CBD-treated (OVX-CBD; 10 mg/kg/day, oral gavage) groups. Treatment began on postoperative day 2 and continued for 21 days. Tail-skin temperature, a surrogate marker of heat dissipation, was assessed by infrared thermography on day 14. Energy metabolism was evaluated by indirect calorimetry on day 21. Uterine weight was measured as a biomarker of estrogen depletion. Results: Ovariectomy significantly increased tail temperature compared to SHAM-V. CBD treatment completely prevented this effect, with OVX-CBD animals exhibiting thermographic profiles similar to SHAM-V. Uterine atrophy was not reversed by CBD. No differences in the calorimetry parameter were observed among groups. Conclusions: This study provides novel preclinical evidence that cannabidiol attenuates ovariectomy-induced heat dissipation in rats, without detectable effects on uterine weight or metabolic parameters. These findings suggest that CBD may represent a potential non-hormonal approach for the management of menopausal vasomotor symptoms; however, further studies are required to elucidate the underlying mechanisms and to determine its translational and clinical relevance.
Backgrounds: Astragalus membranaceus (AM), a traditional Chinese medicinal herb, has garnered interest for its potential in anticancer therapy. Preclinical evidence suggests that AM inhibits tumor growth and could mitigate the adverse effects associated with conventional treatments. However, a comprehensive review of its efficacy across various cancer types is lacking. Objectives: This systematic review evaluates the preclinical evidence for the antitumor efficacy of AM and its active components to inform future clinical translation. Methods: A systematic literature search was conducted in PubMed, EMBASE, and Web of Science from their earliest records to February 2026 to identify relevant studies. Studies reporting on the antitumor effects of AM or its constituents in murine models were included. Results: Seventy-six studies met the inclusion criteria. The most frequently investigated compounds were formononetin (21 studies), Astragaloside IV (20 studies), and Astragalus polysaccharide (16 studies). The evidence indicates that these compounds, both as monotherapies and in combination with standard chemotherapy, can inhibit tumor growth and potentiate antitumor efficacy. Conclusions: AM and its bioactive constituents exhibit promising anticancer effects against solid tumors, including breast, lung, hepatocellular, and colorectal carcinomas in preclinical models. Clinical investigation is warranted to confirm the utility of AM for cancer therapy.
Background: Geraniol is an acyclic monoterpene widely distributed in the essential oils of aromatic species such as Cymbopogon citratus, Pelargonium graveolens, and Rosa damascena, It is known for its antioxidant, anti-inflammatory, neuroprotective, and antitumor activities. Methods: This study aimed to investigate, through network pharmacology and computational ADMET modeling, the molecular mechanisms and pharmacological potential of geraniol, integrating drug-likeness parameters, toxicity prediction, and multitarget interactions. Results: A total of 25 core targets were identified, mainly involved in inflammation, oxidative stress, apoptosis, and transcriptional regulation. Geraniol exhibited a favorable drug-likeness profile, high predicted intestinal absorption, and low systemic toxicity, supporting its pharmaceutical applicability. Mechanistically, it modulates the Nrf2/HO-1 ↔ NF-κB axis, reducing reactive oxygen species, pro-inflammatory cytokines (TNF-α, IL-1β, IL-6), and apoptotic markers (caspases, Bax), while enhancing antioxidant enzymes (SOD, CAT, GPx) and antiapoptotic proteins (Bcl-2). Conclusions: These findings confirm its multitarget and pleiotropic nature, highlighting its potential as a therapeutic candidate for inflammatory, metabolic, and neurodegenerative disorders. Furthermore, this study provides a robust mechanistic rationale for future in vitro and in vivo validation, as well as for the design of nanostructured formulations to improve geraniol’s bioavailability and therapeutic safety.
Background/Objectives: Periodontal disease is a condition marked by the destruction of tooth-supporting tissues, driven by an exaggerated immune response to an unbalanced dental biofilm. Conventional treatments struggle due to antimicrobial resistance and the biofilm’s protective extracellular matrix. This study evaluates the potential of bacteriophages as an innovative strategy for managing periodontal disease. Methods: This research employed a qualitative approach using Discursive Textual Analysis, with IRAMUTEQ version 0.8 alpha 7 (Interface de R pour les Analyses Multidimensionnelles de Textes et de Questionnaires) software. The search was conducted in the Orbit Intelligence and PubMed databases, for patents and scholarly articles, respectively. The textual data underwent Descending Hierarchical Classification, Correspondence Factor Analysis, and Similarity Analysis to identify core themes and relationships between words. Results: The analysis revealed an increase in research and patent filings concerning phage therapy for periodontal disease since 2017, emphasizing its market potential. The primary centers for intellectual property activity were identified as China and the United States. The study identified five focus areas: Genomic/Structural Characterization, Patent Formulations, Etiology, Therapeutic Efficacy, and Ecology/Phage Interactions. Lytic phages were shown to be effective against prominent pathogens such as Fusobacterium nucleatum and Enterococcus faecalis. Conversely, the lysogenic phages poses a potential risk, as they may transfer resistance and virulence factors, enhancing pathogenicity. Conclusions: Phage therapy is a promising approach to address antimicrobial resistance and biofilm challenges in periodontitis management. Key challenges include the need for the clinical validation of formulations and stable delivery systems for the subgingival area. Future strategies, such as phage genetic engineering and data-driven cocktail design, are crucial for enhancing efficacy and overcoming regulatory hurdles.
Background: The growing recognition of shared molecular pathways and molecular signatures between cardiovascular diseases and cancer has motivated interest in exploring antihypertensive-associated chemical space for oncological applications. Concurrently, artificial intelligence (AI)-driven molecular generation has enabled the rapid creation of virtual lead candidates for specific therapeutic indications, although their broader biological interaction profiles often remain unexplored. Methods: In this paper, we explore the computational screening of a library of AI-generated antihypertensive virtual lead compounds to evaluate their polypharmacological anticancer potential. The compounds were originally designed and prioritized for modulating β-adrenergic receptors but are here re-evaluated in a cancer-focused context using a multi-stage in silico approach. We chose five (5) known cancer target proteins and performed compound profiling for drug-likeness, pharmacokinetic suitability, and safety. Docking simulations, binding free energy estimates, molecular interaction mapping, and pharmacophore modeling were used to evaluate the molecules’ interactions with the cancer-linked protein targets. We employed the binding free energy estimates of the ligand–protein complexes to determine compounds with polypharmacological anticancer potential. In addition, molecular dynamics simulations of some of the compounds with polypharmacological anticancer potential were employed to evaluate binding stability and dynamic behavior of selected ligand–target complexes. Results: Several compounds showed good docking scores, physicochemical characteristics, and pharmacokinetic profiles. Also, the results reveal that several AI-generated antihypertensive virtual leads exhibit favorable multi-target binding profiles, with consistent docking affinities and stable interaction networks across multiple cancer-related targets. Conclusions: Our findings suggest that several of the hypothetically evaluated compounds exhibit favorable physicochemical properties, acceptable predicted pharmacokinetic and safety profiles, and consistent predicted binding affinities across multiple cancer-relevant targets.
The landscape of oncologic therapies has undergone large changes since the introduction of monoclonal antibody (mAb) based immunotherapies in the late 1990s and early 2000s. MAb-based therapeutics, also called biologics or large molecules, have distinct pharmacological characteristics compared to chemotherapeutics and small molecules. Development of biologics requires thorough assessment of pharmacokinetic (PK) and pharmacodynamic (PD) characteristics to ensure safety and demonstration of efficacy. This review provides an overview of the clinical pharmacology packages of biologics for the treatment of oncologic malignancies approved by the U.S. Food and Drug Administration (FDA) over the past decade (January 2015 and August 2025). The conduct of population PK (PopPK) and exposure-eesponse (E-R) analyses, as well as assessments for drug–drug interactions (DDIs), immunogenicity, and QT prolongation risk are discussed. The aim of this review is to provide insight into the clinical pharmacology assessments for approval of antibody-based therapies in oncology as well as provide a longitudinal view of clinical pharmacology packages in this space.
Oxidative stress, caused by an imbalance between the production of reactive oxygen species and endogenous antioxidant capacity, is a key etiological factor in numerous pathologies, including neurodegenerative and cardiovascular diseases. The limited clinical efficacy of conventional antioxidants is primarily due to their insufficient accumulation within the mitochondria, the main site of intracellular ROS generation. This article reviews the design and application of Mitochondria-Targeted Antioxidants, which represent a major advance in precision medicine. The design of these compounds involves linking an antioxidant “payload” to a lipophilic cation, such as the triphenylphosphonium group. This positive charge leverages the negative electrochemical gradient across the inner mitochondrial membrane to drive the antioxidant into the organelle. This mechanism allows the drug to reach concentrations over 100 times higher than non-targeted alternatives. The discussion encompasses the structure-activity analysis of the carrier, the payload (e.g., quinone derivatives), and the linker, which determine optimal subcellular partitioning and scavenging efficiency. Preclinical data highlight the therapeutic potential of this approach, showing strong neuroprotection in models of Parkinson’s and Alzheimer’s diseases, as well as improved outcomes in cardiovascular and ocular health. By restoring redox balance specifically within the mitochondria, these targeted therapies offer a more effective way to treat chronic oxidative damage.
