A series of 3-substituted-thiochroman-4-one semicarbazone derivatives were designed based on the
bioisosterism and combination principle in drug design. The target compounds were prepared from 3-substitutedthiochroman-
4-one (1) and 4-substituted-semicarbazides( 2), their structures were confirmed by MS and 1H NMR. The
antifungal assay was carried out in vitro by twofold dilution. The result shows that all the compounds are of antifungal
activities against the tested fungi at different levels.
根据药物设计中的生物异构和组合原理,设计了一系列 3-取代-硫杂苯并吡喃-4-酮半咔唑酮衍生物。目标化合物由 3-取代的二氢苯并二氢吡喃-4-酮(1)和 4-取代的半咔唑(2)制备而成,并通过 MS 和 1H NMR 确认了它们的结构。通过两倍稀释法在体外进行了抗真菌试验。结果表明,所有化合物都对受试真菌具有不同程度的抗真菌活性。
