Several different heterocyclic systems were compared as PDE5 inhibitor scaffolds. In addition to the known 3H-imidazo[5,1-f][1,2,4]triazin-4-ones and pyrazolopyrimidinones, isomeric imidazo[1,5-a][1,3,5]triazin-4(3H)-ones were also shown to be potent and selective PDE inhibitor scaffolds with in vivo activity. SAR trends were elucidated for sulfonamide derivatives with generality across different scaffolds
比较了几种不同的杂环系统作为PDE5抑制剂支架。除了已知的3H-咪唑并[5,1-f] [1,2,4]三嗪-4-酮和吡唑并吡喃二酮外,咪唑并[1,5-a] [1,3,5]三嗪-4( 3H)-一也被证明是具有体内活性的有效的和选择性的PDE抑制剂支架。阐明了在不同支架上具有普遍性的磺酰胺衍生物的SAR趋势。
