Abstract A series of 21 novel compounds containing a thiosemicarbazone moiety were designed and synthesised based on hit compound 1 from our in-house compound library screening. Most compounds showed potent antifungal activity in vitro against seven common pathogenic fungi. Notably, all compounds showed high potency against Candida glabrata 537 (MIC = ≤0.0156-2 µg/mL). Of note, compounds 5j and 5r
摘要 基于我们内部化合物库筛选的命中化合物1 ,设计并合成了一系列包含缩氨基硫脲部分的 21 种新型化合物。大多数化合物在体外对七种常见病原真菌显示出有效的抗真菌活性。值得注意的是,所有化合物都显示出对光滑念珠菌537的高效力(MIC = ≤0.0156-2 µg/mL)。值得注意的是,化合物5j和5r对Candida krusei 4946 和Candida auris 922 表现出优异的抗真菌活性。此外,化合物5j和5r还对 15 C. glabrata表现出高效力分离物的 MIC 值范围为 0.0625 µg/mL 至 4 µg/mL,化合物5r略优于5j。此外,化合物5r对C. glabrata的生物膜形成有一定的抑制作用。此外,化合物5r对 HUVEC 的细胞毒性最小,IC 50值为 15.89 µg/mL,在 64 µg/mL 时无溶血作用。总之,这些结果表明有前途的先导化合物5r值得进一步研究。
