Synthesis, characterization and investigation of antibacterial and antifungal activities of twelve camphor based
2,4-disubstituted 1,3-thiazoles is presented. Their structures were determined using NMR, IR, FAB MS and HRMS analyses.
Among the derivatives, 3i and 5 were found to exhibit antifungal and antibacterial activities comparable to that of fluconazole
and ciprofloxacin against yeast belonging to Candida spp., MIC 0.12-0.98 μg/ml and Gram-positive bacteria including
both pathogenic S. aureus and opportunistic S. epidermidis, MIC 0.98-7.81 μg/ml, B. subtilis and B. cereus, MIC
3.91-31.25 μg/ml, and M. luteus, MIC 0.98 μg/ml species, respectively. Molecular docking studies of all compounds into
the active sites of microbial enzymes indicated a possible targets SAP and NMT, thiazoles 3a-j, 4, 5 showed more favourable
affinity than the native ligand.
本文介绍了十二种樟脑基2,4-二取代1,3-噻唑的合成、表征及其抗菌和抗真菌活性研究。它们的结构通过NMR、IR、FAB MS和HRMS分析确定。在这些衍生物中,3i和5表现出与氟康唑和环丙沙星相当的抗真菌和抗菌活性,对属于念珠菌属的酵母菌(MIC 0.12-0.98 μg/ml)、包括致病性金黄色葡萄球菌和机会性表皮葡萄球菌在内的革兰氏阳性细菌(MIC 0.98-7.81 μg/ml)、枯草芽孢杆菌和蜡样芽孢杆菌(MIC 3.91-31.25 μg/ml)以及藤黄微球菌(MIC 0.98 μg/ml)具有活性。所有化合物的分子对接研究显示,它们与微生物酶的活性位点结合,可能的目标是SAP和NMT,噻唑3a-j、4、5显示出比原生配体更有利的亲和性。
