In vitro propagation using shoot apical meristem culture provides a reliable method for producing uniform, disease-free sugarcane planting material. This study aimed to optimize hormone regimes for two French genotypes, FG03-418 and FG04-754, and highlighted their genotype-specific responses that improved shoot initiation, multiplication, rooting, and acclimatization efficiency. This study optimized in vitro propagation of two French sugarcane genotypes (FG03-418 and FG04-754) using shoot apical meristems under a randomized design, revealing genotype-specific responses to plant growth regulators. FG03-418 showed optimal initiation on MS medium with 0.75 mg/L 6-Benzylaminopurine (BAP), while FG04-754 responded best at 1.25 mg/L BAP. During multiplication, FG03-418 produced the highest shoot number (11.56 ± 0.68) at 1.5 mg/L BAP + 0.5 mg/L 1-Naphthaleneacetic acid (NAA) and achieved maximum shoot length and leaf number (5.47 ± 0.31) at 2.0 mg/L BAP + 0.5 mg/L NAA, whereas FG04-754 exhibited optimal shoot growth at 2.0 mg/L BAP + 0.5 mg/L NAA. Root induction was most effective on half-strength MS medium supplemented with NAA, at 5.0 mg/L for FG03-418 and 4.0 mg/L for FG04-754, producing mean root lengths of 7.05 ± 0.13 cm and 5.27 ± 0.14 cm, respectively. Acclimatization in a greenhouse substrate of sand, soil, and compost (1:2:1) resulted in survival rates above 95
This study explores the potential of synthesized and crystallized 4 '-bromo-5-(furan-2-yl)-1,6-dihydro-[1,1 '-biphenyl]-3(2H)-one (BFDhB) against Ebola virus disease (EVD). We performed computational optimization using B3LYP-GD3 at the aug-cc-pVDZ level of the theory. Hirshfeld plots reveal that the predominant interactions in these molecules are H & ctdot;H (34.2%), O & ctdot;H (19.6%), C & ctdot;H (22.4%), H & ctdot;Br (16.3%), C & ctdot;Br (3.7%), C & ctdot;C (1.9%), C & ctdot;O (1.3%) and O & ctdot;Br (0.6%). The compounds showed significant biological potential, forming insightful bonding interactions with Ebola virus proteins, resulting in a binding affinity of -7.3 kcal/mol with protein 5HJ3 and -6.0 kcal/mol with protein 5T3T. The compound also formed three hydrogen bonds with 5HJ3 and two hydrogen bonds with the protein 5T3T. In silico drug likeness predicted a high gastrointestinal absorption rate, BBB permeance and positive lead likeness. The study presents BFDhB as a lead compound for consideration as a therapeutic option for Ebola, pending further experimental findings.
In the current study, new Schiff base compounds 1-4 were synthesized by the combination of various aldehydes such as propionaldehyde, cinnamaldehyde, furan-2-carbaldehyde and thiophen-2-carbaldehyde with pyrazolefunctionalized amines using a magnetic stirrer. Characterization (color, appearance, melting point, IR, mass, 1H and 13CNMR, and single-crystal XRD analysis), antioxidant characteristics, and molecular docking investigations of the synthesized compounds were explored in this work. The crystal data of the heteroatom isomers (i.e., compounds 3 and 4) are discussed in detail, where the pyran and thiopyran are in the planar conformation and molecule 3 is stabilized with a range of hydrogen bonds, although both 3 and 4 are stabilized with inter- and intra H-bonds, and pi...pi interactions. The antioxidant properties of compounds 1-4 were assessed using an in vitro DPPH assay. In comparison to the ascorbic acid standard (98.95 %), compound 1 (96.10 %) expressed parallel antioxidant potential at a concentration of 0.4 mg/mL. Molecular docking simulations were performed to identify the binding interactions between these compounds and target biomolecules. Compound 2 ensured the greatest binding (Glide score -7.98) to the epidermal growth factor receptor (EGFR) protein.
A series of new pyrazole (1,2-azole) Schiff bases 1-4 were synthesized by combining benzaldehyde or substituted benzaldehydes with functionalized amines under mild conditions. The synthesized Schiff bases were characterized by their physical properties, spectral characterization (IR, mass, 1H NMR, D2O exchange, and 13C NMR), and single-crystal X-ray crystallography. Since pyrazole is an important class of pharmacophore with diverse pharmacological activities, the present study aimed to investigate its radical scavenging ability by the DPPH method. Compounds 3 and 4 exhibited notable antioxidant activity even at concentrations below 1.0 mu g/mL. Furthermore, to explore the anticancer efficacy, molecular docking was conducted for all compounds. Among them, compound 3 exhibited a higher binding affinity toward EGFR kinase than both the co-crystallized compound (AQ4) and the other newly synthesized compounds, indicating its potential as an EGFR kinase inhibitor. Consequently, compound 3 was tested for cytotoxicity against MCF-7 cell lines at various concentrations using the MTT assay.
Cancer is one of the leading causes of mortality worldwide and is recognized as a complex, multifactorial disease with no clearly defined etiology for its onset and progression. Long non-coding RNAs (lncRNAs) are widely distributed across the human body and play varied roles in regulating cellular processes. In recent years, they have gained the attention of the scientific community as key regulators of cancer due to their diverse functional roles and complex regulatory mechanisms. Aberrant expression of lncRNAs contributes to tumor progression, functioning as oncogenes that modulate various pathways through different mechanisms. Early technologies could not study lncRNAs effectively and considered it as “junk” RNA. Studies using gene-expression analyses, functional experiments, and animal-based models have shown that dysregulated lncRNAs are implicated in the maintenance of cancer stem cells (CSCs) and in driving therapeutic resistance. Additionally, lncRNAs have shown promise as valuable biomarkers for cancer diagnosis, prognosis, predicting patient outcomes, and guiding treatment strategies. Moreover, therapeutic strategies targeting lncRNAs, such as antisense oligonucleotides (ASOs), RNA interference (RNAi), exosome-based delivery systems, nanomedicine, virus-mediated therapy, and CRISPR-Cas technologies, have opened new avenues for cancer treatment. This review highlights the diverse roles of lncRNAs in therapeutic resistance and emphasizes their clinical potential as diagnostic and prognostic tools and emerging therapeutic strategies.
