The wound-healing process is accelerated by inhibiting proteins that decelerate the wound-healing pathway. One of the active proteins involved in enhancing healing at the nuclear level and in gene expression is catenin. Inhibition of Glycogen Synthase Kinase 3β (GSK3 β) phosphorylates and degrades catenin via the downstream Wnt signalling pathway, thereby stabilizing catenin. A medicated wound dressing transdermal patch designed with fusion of bio wastes, viz. physiologically clotted fibrin, fish scale collagen, and the ethanolic extract of (L.) and spider web, was analysed against GSK3β to enhance healing. In our earlier studies, the compounds present in the transdermal patch were identified using GC-MS analysis; 12 compounds exhibiting the wound healing mechanism were analyzed using PASS software and filtered out. From these 12 compounds, 6 compounds that possessed drug-likeness were screened by SwissADME and vNN-ADMET to dock against GSK3β in the present work. The PyRx results confirmed the binding of the six ligands to the active site of the target protein. Though the remaining filtered ligands also exhibited inhibitory activity, Molecular dynamics simulation studies were carried out with 100 ns on a complex of 10,12 Tricosadiyonic acid, Nopyl acetate and 2 Methyl 4 Heptanol as they showed binding affinity of -6.2Kcal/mol, -5.7Kcal/mol and -5.1Kcal/mol respectively. The stability of the complex was validated using MD simulation parameters RMSD, RMSF, Rg, and Number of Hydrogen bonds. These results implied that the transdermal patch would be efficient in accelerating the wound healing process through the inactivation of GSK3β.Communicated by Ramaswamy H. Sarma.
伤口愈合过程通过抑制减缓伤口愈合途径的蛋白质来加速。参与增强核水平和基因表达愈合的活性蛋白之一是连环蛋白。通过下游 Wnt 信号通路,糖原合酶激酶 3β(GSK3β)的抑制使连环蛋白磷酸化和降解,从而稳定连环蛋白。一种设计用于融合生物废物(即生理凝结的纤维蛋白、鱼鳞胶原蛋白和乙醇提取物)的药用伤口愈合贴剂,旨在抑制 GSK3β 以促进愈合。在我们之前的研究中,使用 GC-MS 分析对透皮贴剂中的化合物进行了分析;使用 PASS 软件分析了 12 种具有伤口愈合机制的化合物,并进行了过滤。从这 12 种化合物中,通过 SwissADME 和 vNN-ADMET 筛选出具有药物相似性的 6 种化合物,并在本工作中对接 GSK3β。PyRx 结果证实了这 6 种配体与靶蛋白活性位点的结合。尽管其余筛选出的配体也表现出抑制活性,但我们对 100ns 的 10,12 二十三烷二酸、正辛酯和 2-甲基-4-庚醇的复合物进行了分子动力学模拟研究,因为它们表现出-6.2Kcal/mol、-5.7Kcal/mol 和-5.1Kcal/mol 的结合亲和力。使用 MD 模拟参数 RMSD、RMSF、Rg 和氢键数量验证了复合物的稳定性。这些结果表明,透皮贴剂通过使 GSK3β 失活将有效加速伤口愈合过程。
