extinctions due to fungal drug resistance. Aimed to alleviate the situation, new effort was made to develop novel purinylthiazolylethanone derivatives, which were expected to combat the fungal drug resistance. Some prepared purinylthiazolylethanone derivatives possessed satisfactory inhibitory action towards the tested fungi, among which compound 8c gave a MIC value of 1 μg/mL against C. albicans.
由于真菌耐药性,最近出现了前所未有的真菌和真菌样感染,导致了一些最严重的死亡和灭绝。为了缓解这种情况,人们做出了新的努力来开发新型嘌呤基噻唑基乙酮衍生物,有望对抗真菌耐药性。一些制备的嘌呤基噻唑基乙酮衍生物对受试真菌具有令人满意的抑制作用,其中化合物8c对白色念珠菌的MIC值为1 μg/mL 。活性分子8c能够以不可检测的抗性以及低血液毒性和细胞毒性杀死白色念珠菌。此外,它可能会阻碍白色念珠菌的生长生物膜,从而避免耐药性的发生。机制研究表明,嘌呤基噻唑基乙酮衍生物8c导致细胞壁损伤和细胞膜破裂,观察到蛋白质渗漏和细胞质膜去极化。因此,真菌乳酸脱氢酶活性降低,代谢受阻。同时,活性氧(ROS)和活性氮(RNS)水平的增加扰乱了氧化还原平衡,导致对真菌细胞的氧化损伤和杀菌作用。
