Continuing research with our earlier finding of sildenafil based analogs in the search of new inhibitors of PDE5 for erectile dysfunction suggested that there is a scope of modifications at N-methylpiperazine ring with hydrophobic region followed by hydrogen bond donor or acceptor region. However, the leads identified earlier had some limitations like poor pharmacokinetic (PK) profile, low aqueous
继续研究我们早期发现的基于西地那非的类似物,寻找治疗勃起功能障碍的新 PDE5 抑制剂,表明 N-甲基哌嗪环上存在一定范围的修饰,疏水区后面是氢键供体或受体区域。然而,早期发现的先导化合物存在一些局限性,例如药代动力学 (PK) 特征较差、水溶性较低和生物利用度较差。在这个方向上,设计、合成了一系列新的基于西地那非的类似物,并筛选了它们的 PDE5 抑制活性。在该系列中,化合物18被发现具有优异的体外活性,对PDE5同工酶具有选择性,体内活性和药代动力学特征也优异。化合物18的cyp抑制和CaCO 2渗透性也优异。
