A method of identifying an antifungal agent which targets a DHODH protein (alias PyrE, dihydroorotate dehydrogenase, EC: 1.3.99.11) of a fungus comprising contacting a candidate substance with a fungal DHODH protein and determining whether the candidate substance binds or modulates the DHODH protein, wherein binding or modulation indicates that the candidate substance is an antifungal agent. Specific examples concern Aspergillus fumigatus and Candida albicans DHODH proteins. DHODH inhibitors with a Quinazolinone core are also disclosed.
一种鉴定靶向真菌DHODH蛋白(别名PyrE,二氢乳酸酸脱氢酶,EC:1.3.99.11)的抗真菌剂的方法,包括将候选物质与真菌DHODH蛋白接触,并确定候选物质是否与DHODH蛋白结合或调节,其中结合或调节表明候选物质是一种抗真菌剂。具体例子涉及Aspergillus fumigatus和Candida albicans DHODH蛋白。还公开了一种具有喹唑啉酮核心的DHODH抑制剂。
