The screening of hair follicles, dermal papilla cells, and keratinocytes through , , and histology has previously been reported to combat alopecia. has been used conventionally to cure skin and hair disorders, although its effect on 5-reductase II is still unknown. Currently, we aim to analyze the phytotherapeutic impact of F. benghalensis leaf extracts (FBLEs) for promoting hair growth in rabbits along with inhibition of the steroid isozyme 5-reductase II. The inhibition of 5-reductase II by FBLEs was assessed by RP-HPLC, using the NADPH cofactor as the reaction initiator and Minoxin (5%) as a positive control. studies were performed using AutoDock Vina to visualize the interaction between 5-reductase II and the reported phytoconstituents present in FBLEs. Hair growth in female albino rabbits was investigated by applying an oral dose of the FBLE formulation and control drug to the skin once a day. The skin tissues were examined by histology to see hair follicles. Further, FAAS, FTIR, and antioxidants were performed to check the trace elements and secondary metabolites in the FBLEs. The results of RP-HPLC and the binding energies showed that FBLEs reduced the catalytic activity of 5-reductase II and improved cell proliferation in rabbits. The statistical analysis ( < 0.05 or 0.01) and percentage inhibition (>70%) suggested that hydroalcoholic FBLE has more potential in increasing hair growth by elongating hair follicle's anagen phase. FAAS, FTIR, and antioxidant experiments revealed sufficient concentrations of Zn, Cu, K, and Fe, together with the presence of polyphenols and scavenging activity in FBLE. Overall, we found that FBLEs are potent in stimulating hair follicle maturation by reducing the 5-reductase II action, so they may serve as a principal choice in drug designing to treat hair loss.
此前已有报道称,通过[具体方法1]、[具体方法2]和组织学对毛囊、真皮乳头细胞和角质形成细胞进行筛选可对抗脱发。[药物名称]传统上用于治疗皮肤和毛发疾病,尽管其对5 - 还原酶II的作用尚不清楚。目前,我们旨在分析孟加拉榕树叶提取物(FBLEs)对促进家兔头发生长以及抑制类固醇同工酶5 - 还原酶II的植物治疗作用。采用反相高效液相色谱法(RP - HPLC),以烟酰胺腺嘌呤二核苷酸磷酸(NADPH)辅因子作为反应引发剂,米诺地尔(5%)作为阳性对照,评估FBLEs对5 - 还原酶II的抑制作用。使用自动对接软件AutoDock Vina进行[相关研究名称]研究,以可视化5 - 还原酶II与FBLEs中报道的植物成分之间的相互作用。通过每天一次将口服剂量的FBLE制剂和对照药物涂抹于雌性白化家兔皮肤来研究其毛发生长情况。通过组织学检查皮肤组织以观察毛囊。此外,还进行了火焰原子吸收光谱法(FAAS)、傅里叶变换红外光谱法(FTIR)和抗氧化剂检测,以检查FBLEs中的微量元素和次生代谢产物。RP - HPLC结果和结合能表明,FBLEs降低了5 - 还原酶II的催化活性,并促进了家兔细胞增殖。统计分析(P < 0.05或0.01)和抑制率(>70%)表明,水醇提取物FBLE在延长毛囊生长期以增加毛发生长方面具有更大潜力。FAAS、FTIR和抗氧化剂实验揭示了FBLE中锌、铜、钾和铁的充足浓度,以及多酚的存在和清除活性。总体而言,我们发现FBLEs通过降低5 - 还原酶II的作用,在刺激毛囊成熟方面具有效力,因此它们可能成为治疗脱发药物设计中的主要选择。
