A new series of thiazole-containing triazole antifungals was synthesized and evaluated for antifungal activity against a variety of clinically isolated pathogenic fungi in vitro and against systemic candidosis in vivo. Among these compounds, (±)-1-(2, 4-difluorophenyl)-1-[4-(2, 4-difluorophenyl)thiazol-2-yl]-2-(1H-1, 2, 4-triazol-1-yl)ethanol (ER-24161) showed the most potent and well-balanced in vitro activities and excellent in vivo efficacy. We also achieved an enantioselective synthesis of the more potent enantiomer of ER-24161.
合成了一系列含有噻唑结构的三唑类抗真菌药物,并评估了它们对多种临床分离的致病真菌的体外抗真菌活性和对系统性念珠菌病的体内疗效。在这些化合物中,(±)-1-(2,4-二氟苯基)-1-【4-(2,4-二氟苯基)噻唑-2-基】-2-(1H-1,2,4-三唑-1-基)乙醇(ER-24161)表现出最强的体外活性平衡和优异的体内疗效。我们还成功实现了ER-24161更具活性的对映体的对映选择性合成。
