CYP51 inhibitor, scaffold hopping was used to design structurally diverse new compounds and expand the structure–activity relationships of the lead structure. Five kinds of scaffolds, namely benzimidazole, benzoxazole, benzothiazole, quinazolin-4-one and carboline, were chosen for synthesis. In vitro antifungal activity data and results from molecular docking revealed that the scaffold was important for
侵袭性真菌感染的发生率和相关死亡率急剧增加。尽管唑类是一线抗真菌剂,但交叉耐药性和肝毒性是它们的两个主要限制。新型非唑类铅化合物的发现将有助于克服这些问题。根据我们先前报道的苯并吡喃非唑CYP51抑制剂,使用脚手架跳跃来设计结构多样的新化合物并扩展前导结构的构效关系。选择了五种支架,即苯并咪唑,苯并恶唑,苯并噻唑,喹唑啉-4-酮和咔啉。体外抗真菌活性数据和分子对接的结果表明,支架对抗真菌活性很重要。
