Novel cycloalkene‐fused thienopyrimidine analogues with enhanced phosphodiesterase 5 (PDE5) inhibitory properties are presented. The structure of the reported scaffold was modulated through variation of the terminal cycloalkene ring size, as well as by varying the substituents at position 4 through the attachment of different groups including aniline, benzylamine, cyclohexylethylamine, methyl/acetyl/aryl
提出了具有增强的磷酸二酯酶 5 (PDE5) 抑制特性的新型环烯烃稠合噻吩并嘧啶类似物。报道的支架的结构通过改变末端环烯烃环大小以及通过连接不同基团(包括苯胺、苄胺、环己基乙胺、甲基/乙酰基/芳基哌嗪和芳基腙)来改变第 4 位的取代基进行调节. 具有苄胺取代基和环庚烯作为末端环的化合物15Y显示出最高的PDE5抑制活性,IC50值低至190 nM,并且对PDE7和PDE9具有良好的选择性。
