antifungals in C. albicans poses a threat to public health. Two series of novel azole derivatives, short and extended derivatives, have been designed, synthesised and investigated for CYP51 inhibitory activity, binding affinity and minimum inhibitory concentration (MIC) against C. albicans strains. The short derivatives were more potent against the C. albicans strains (e. g., MIC 2‐(4‐chlorophenyl)‐N‐(2
真菌感染是一个全球性问题,每年影响全世界1.5亿人,其中75万是侵袭性念珠菌感染引起的。唑类药物是抵抗真菌感染的一线治疗方法。但是,目前对白色念珠菌中的唑类抗真菌药的耐药性对公共健康构成了威胁。设计,合成和研究了两个系列的新型唑衍生物,即短衍生物和扩展衍生物,其对白色念珠菌菌株的CYP51抑制活性,结合亲和力和最小抑制浓度(MIC)。短衍生物对白色念珠菌菌株更具效力(例如MIC 2–(4-氯苯基)‐N‐(2,4-二氯苄基)‐3‐(1 H-咪唑-1-基)丙酰胺(5 f)<0.03μg/ mL,N-(4-((4-氯苯基)磺酰胺基)苄基)-2-苯基-3-(1 H - 1,2,4-三唑-1-基丙酰胺(12 c),1μg/ mL,氟康唑0.125μg/ mL),但两者均显示出可比的酶结合和抑制作用(5 f K d 62±17 nM,IC 50 0.46μM; 12 c K d 43±18 nM,IC
