To investigate icariin’s regulation of marrow fatty acid metabolism and stearoyl-CoA desaturase (SCD) indices in preventing ovariectomy-induced osteoporosis. Thirty-six female Sprague-Dawley rats underwent sham surgery or ovariectomy and were treated with either icariin (125 mg/kg/day) or vehicle via oral gavage for 12 weeks, 6 days per week. Bone marrow was collected from tibias for fatty acid profiling via gas chromatography–mass spectrometry. Serum levels of bone-specific alkaline phosphatase (BALP) and tartrate-resistant acid phosphatase 5b (TRACP-5b) were measured using Enzyme-Linked Immunosorbent Assay. Tibial trabecular microstructure was assessed by micro-CT. Ovariectomy significantly altered marrow fatty acid composition, marked by increased palmitic acid (C16:00) and palmitoleic acid (C16:1 n-7), decreased stearic acid (C18:00) and arachidonic acid (C20:4 n-6), and elevated SCD indices. These changes were associated with deteriorated bone microarchitecture and impaired bone turnover. Icariin treatment effectively normalized marrow fatty acid levels, suppressed SCD indices, and consequently attenuated bone loss by improving bone volume fraction, trabecular number, and thickness, while reducing trabecular separation. Additionally, icariin restored the balance of bone turnover markers, increasing BALP and decreasing TRACP-5b. Significant correlations were identified between specific fatty acids and both bone structural parameters and remodeling markers. Icariin attenuates osteoporotic bone loss by preventing ovariectomy-induced disturbances in marrow fatty acid metabolism, particularly through the suppression of SCD indices and normalization of C16:00, C16:1 n-7, and C18:00 levels. This study highlights the critical role of lipid homeostasis in bone integrity and identifies icariin as a promising lipid-modulating candidate for postmenopausal osteoporosis.
Stellera chamaejasme L., a traditional Chinese medicinal herb used for treating skin disorders such as psoriasis, was investigated to identify its bioactive antipsoriatic components and elucidate its underlying mechanisms of action. In an imiquimod (IMQ)-induced psoriasis-like skin lesion mouse model, the ethyl acetate (Et) fraction exhibited the most significant therapeutic effect among various solvent-partitioned extracts, as demonstrated by hematoxylin-eosin (H&E), immunohistochemistry (IHC), and immunofluorescence (IF) analyses. The bioassay-guided fractionation of the Et extract led to the isolation of eleven compounds (1-11), whose structures were characterized using nuclear magnetic resonance (NMR) spectroscopy and X-ray crystallography. Among them, wikstroelide J (WJ, compound 11) exhibited the most potent activity, inhibiting M5-induced hyperproliferation of HaCaT keratinocytes (IC₅₀ = 9.4 μM) and alleviating psoriasis-like skin lesions in vivo. Mechanistically, WJ modulated T-cell subsets and downregulated the JAK2/PI3K/AKT signaling pathway, with pathway involvement further supported by the use of the JAK2 inhibitor AG490. These findings highlight WJ as a promising antipsoriatic agent that targets the JAK2/PI3K/AKT pathway. Future studies will aim to improve its pharmacological properties and assess its efficacy in clinical settings, although current limitations, such as a lack of pharmacokinetic and clinical data, remain to be addressed.
BACKGROUND:Skin disorders are a collection of prevalent and frequent illnesses that have significant impacts on daily life. Currently, a limited number of effective therapeutic drugs are available that fall far short of the clinical needs; most medications usually offer chronic alleviation instead of treatment. Diterpenoids are the main components of many plant essential oils, such as lemon oil, turpentine, peppermint oil and camphor oil. Most of these compounds are water insoluble, volatile, aromatic, and oily substances. PURPOSE:This paper systematically introduces major skin illnesses in regular life, lists related diterpenoids and their clinical applications, and summarizes the current status of clinical research on related diterpenoids and their structural formulas. This review may increase the research focus on dermatological illnesses by providing helpful knowledge for individuals involved in drug research on this subject. METHODS:A thorough review of the literature was conducted using the search parameters "diterpenoid," "skin diseases," "structure" and "pharmacological activity" to retrieve articles from the PubMed, Web of Science, ACS, Elsevier Science and Scopus databases.
Patients with inflammatory bowel disease (IBD) frequently experience osteoporosis (OP) due to factors such as chronic inflammation, malnutrition, and corticosteroid use. However, there is currently a lack of effective pharmacological interventions for the prevention and treatment of IBD-associated OP. Xanthohumol (XAN), a natural flavonoid compound isolated from hops, has shown beneficial effects on both inflammation and osteoporosis. This study aimed to explore the therapeutic effects and potential mechanisms of XAN from hops on IBD-associated OP based on gut microbiota. The IBD-associated OP model was constructed by free drinking of dextran sulfate sodium (DSS). Therapeutic effects of XAN were investigated through disease activity index (DAI) scoring, colon pathology, mucosal barrier function, inflammatory factors, bone metabolism indicators, and femoral Micro-CT. Mechanisms of XAN regulating gut microbiota were preliminarily elucidated by 16S rDNA sequencing and non-targeted metabolomics. XAN could effectively alleviate colonic tissue inflammation and protect the intestinal mucosal barrier, further improve colonic pathological damage, and reduce the DAI scoring in DSS mice. It also exerted anti-IBD-associated OP effects by reducing serum inflammatory factors IL-6, IL-17A, and TNF-α, inhibiting serum CTX-I expression, promoting serum OPG expression, regulating calcium-phosphorus balance, and improving bone density and morphology. More importantly, 16S rDNA sequencing and untargeted metabolomics showed that XAN increased the abundance and diversity of the gut microbiota in DSS mice. By altering the abundance of specific bacterial taxa such as Turicibacter, norank_f__norank_o__Clostridia_UCG-014, norank_f__Muribaculaceae, and Faecalibaculum, XAN changed the metabolites of gut microbiota, thereby regulating the tryptophan (Trp) metabolism pathway, as well as improving the intestinal mucosal barrier and bone metabolism. XAN can improve the pathological injury of the colon and bone loss caused by IBD. The mechanism is to regulate Trp metabolism by intervening in gut microbiota, thereby protecting intestinal mucosal barrier function and promoting bone formation.
BACKGROUND AND PURPOSE:Psoriasis is a multisystem inflammatory disease with a significant impact on quality of life. Stellera chamaejasme, a medicinal plant used in traditional Chinese medicine, shows promise for the treatment of psoriasis. We identified diterpenoids in S. chamaejasme, including a new compound, stellchamain A (SA, 1), with notable antipsoriasis properties. This study explored the effects of SA on psoriasis to determine the mechanisms underlying the therapeutic efficacy of S. chamaejasme. EXPERIMENTAL APPROACH:Compounds isolated by column chromatography were structurally identified using NMR spectroscopy. The effects of SA on IL-17A-treated HaCaT cell viability and apoptosis were assessed using CCK-8 and TUNEL assays. In vivo anti-psoriasis activity of SA was evaluated in a mouse model of imiquimod (IMQ)-induced psoriasis. Network pharmacology, surface plasmon resonance (SPR), drug affinity responsive target stability (DARTS), and cellular thermal shift assays (CETSA) were elucidated the interactions between SA and the targets. KEY RESULTS:SA was isolated from S. chamaejasme along with nine known analogues (2-10). In vivo, SA reduced IMQ-induced epidermal thickness, hyperkeratosis, and perivascular inflammatory cell infiltration. Network pharmacology indicated that SA may function via the interleukin IL-17A/STAT1/S100A9 pathway. The results of SPR assays and molecular docking showed that SA binds to STAT1 with a KD value of 9.24 nM. DARTS and CETSA analyses confirmed a direct and relevant interaction between SA and STAT1. CONCLUSION AND IMPLICATIONS:SA modulates the immunological microenvironment to treat psoriasis by targeting the IL-17A/STAT1/S100A9 axis, representing a potential new treatment for psoriasis and other IL-17A-mediated skin disorders.
To investigate the protective effects and underlying mechanisms of Qin-Zhu-Liang-Xue decoction (QZLX) in atopic dermatitis (AD) and glucocorticoid resistance, we conducted a single-blinded, randomized controlled clinical trial to evaluate the efficacy and safety of this concoction. Network pharmacology analysis was performed and validated through clinical studies. The efficacy, safety, and mechanism of action of QZLX and glucocorticoid receptor (GR) α recombinant protein were assessed in AD mice induced by 2,4-dinitrofluorobenzene (DNFB). Correlation analysis was performed to determine the clinical relevance of GRα. The trial demonstrated that patients who received QZLX showed considerable improvements in their Scoring Atopic Dermatitis (SCORAD) and Dermatology Life Quality Index (DLQI) scores compared with those who received mizolastine at week 4. Network pharmacological analysis identified GRα as a key target for QZLX in AD treatment. QZLX administration increased the serum GRα expression in AD patients, alleviated AD symptoms in mice, decreased inflammatory cytokine expression, and increased GRα expression without affecting liver or kidney function. In addition, GRα recombinant protein improved AD-like skin lesions in DNFB-induced mice. A negative correlation was observed between GRα expression and clinical parameters, including SCORAD, DLQI, and serum IgE levels. QZLX alleviates AD symptoms through the upregulation of GRα and thus presents a novel therapeutic strategy for the prevention of glucocorticoid resistance in AD management.

BACKGROUND:Diabetic ulcer is a common complication of diabetes. It is characterized by a long-term disease course and high recurrence rate. Shengji Huayu Formula (SHF) is an effective formula for treating diabetic ulcers. However, the specific effective parts of SHF remain unclear. Clarifying the active polar site of SHF would be helpful to refine research on the components in SHF that promote wound healing. This research aims to focus on evaluating the activity of polar fractions.METHODS:A diabetic rat model was established by intraperitoneally injecting streptozotocin (STZ) and was adopted to confirm the therapeutic effect of SHF. Four different polarity parts were extracted from SHF and prepared into a cream to evaluate the activity. High-performance liquid chromatography (HPLC) was used to detect chemical constituents in chloroform extracts.RESULTS:It was discovered that dracorhodin, aloe-emodin, rhein, imperatorin, emodin, isoimperatorin, chrysophanol, physcion, and tanshinone IIA were the main components of the chloroform extract from SHF. The results revealed that chloroform extract could effectively accelerate diabetic wound healing by promoting collagen regeneration and epidermal repair. Chloroform extract of SHF could stimulate the generation of vascular endothelial growth factor (VEGF). The results are also indicated that the effective active fraction was the chloroform part, and the method of detecting the main chemical constituents in the active part was successfully established.CONCLUSION:SHF could improve diabetic ulcers by promoting granulation tissue synthesis. In this study, four polar parts (petroleum ether, chloroform, ethylacetate, n-butanol) were extracted from a 95% ethanol extract. In contrast, chloroform polar parts showed a higher wound closure rate, stimulated more collagen regeneration and promoted more production of vascular endothelial cells. In conclusion, the chloroform extract of SHF was the effective polar part in ameliorating diabetic wound healing.
