Exploring the thiazole scaffold for the identification of new agents for the treatment of fluconazole resistant Candida
摘要:
Cyclohexyliden- and 2-methylcyclohexyliden-hydrazo-4-arylthiazoles were synthesized and tested as antifungal agents. All compounds exhibited minimal inhibitory concentration (MIC) values comparable with those of fluconazole (FLC). Moreover, some compounds showed fungicidal activity at low concentration. Worth noting five out of nine compounds were active towards Candida albicans 25 FLC resistant isolated from clinical specimens. The cellular toxicity was evaluated and none of the compounds is toxic at the MIC. On the basis of our data we can conclude that these derivatives are promising agents for the treatment of resistant C. albicans.

antimicrobial activities. The structures of synthesized compounds were established by spectroscopic (FT-IR, 1H NMR, 13C NMR, Mass) and elemental analyses. Both the anti-bacterial and anti-fungalactivities with MIC values of compounds were evaluated. The results of anti-bacterial screening reveal that among all the compounds screened eight compounds showed moderate to good anti-bacterial activity while ten
一系列的亚芳基-2-(4-(4-(4-甲氧基/溴苯基)噻唑-2-基)肼(4a – z)和1-(4-(4-甲氧基/溴苯基)噻唑-2-基)-2合成了-cyclohexydenne / cyclopentylidene肼(5a – b / 6a – b),并对其抗菌性能进行了表征和筛选。通过光谱(FT-IR,1 H NMR,1313 C NMR,质量)和元素分析。用化合物的MIC值评估了抗菌和抗真菌活性。抗菌筛选结果表明,在筛选出的所有化合物中,有八种化合物表现出中等至良好的抗菌活性,而新合成的化合物中有十种表现出良好至优异的抗真菌活性。在测试的化合物中,MIC值在6.25–25μg/ ml范围内的最有效化合物是针对三种真菌菌株viz的4a,4n,4z,5a,5b,6a和6b。白色念珠菌,新型隐球菌和黄曲霉。
