根据真菌羊毛甾醇14α-去甲基化酶的三维结构模型设计、合成了48个新型四氢萘类化合物,所有化合物的结构经过IR,1H NMR和MS确证.体外抗真菌活性研究表明所有化合物对7种临床致病真菌都有抗真菌活性,特别是化合物18,21,22,24的抗真菌活性最强.对接研究显示设计的先导化合物与靶酶活性腔中氨基酸功能残基结合,作用模式不同于氮唑类化合物.结果表明新型四氢萘类化合物是一类全新结构类型的抗真菌化合物.
According to the three-dimensional structure model design of fungal lanosterol 14α-demethylase, 48 novel tetrahydronaphthalene compounds were synthesized and the structures of all the compounds were confirmed by IR, 1H NMR and MS.The in vitro antifungal activity showed that all compounds Seven kinds of clinical pathogenic fungi have antifungal activity, especially the antifungal activity of compounds 18,21,22,24 the strongest docking study showed that the design of lead compounds and target enzyme activity of amino acid residues in the cavity binding mode of action Different from the azole compounds.The results show that the new tetralin compounds are a new class of structural antifungal compounds.
