Based on the outcome of computational docking to the active site of cytochrome P450 14a-demethylase (CYP51), diverse 3,4-disubstituted 5-mercapto-1,2,4-triazoles were prepared and screened for antioxidant and antifungal activities. The docking study of synthesized compounds showed promising binding affinity towards docked enzyme, sterol 14a-demethylase(CYP51) from trypanosome cruzi obtained from a RCSB protein data bank (PDB ID: 3KHM). The synthesized compounds were characterized by IR, 1H NMR and Mass spectral data. Among the novel synthesized compounds IV-6, IV-1 and IV-2 showed maximum antifungal activity against A. niger and C. albicans organism when compared the standard fluconazole. For antioxidant activity, all the compounds showed moderate activity but compound IV-6 and IV-7 showed significant activity when compared to standard ascorbic acid.
根据与细胞色素 P450 14a-demethylase (CYP51)活性位点的计算对接结果,制备了多种 3,4-二取代 5-巯基-1,2,4-三唑,并对其进行了抗氧化和抗真菌活性筛选。对合成化合物进行的对接研究表明,它们与对接酶--从 RCSB 蛋白数据库(PDB ID:3KHM)中获得的克鲁斯锥虫甾醇 14a-demethylase(CYP51) 具有良好的结合亲和力。合成的化合物通过红外光谱、1H NMR 和质谱数据进行了表征。与标准氟康唑相比,新合成的化合物 IV-6、IV-1 和 IV-2 对黑曲霉和白曲霉具有最强的抗真菌活性。在抗氧化活性方面,所有化合物都显示出中等活性,但与标准抗坏血酸相比,化合物 IV-6 和 IV-7 显示出显著活性。
