  trisubstituted pyrazoline scaffold derived from the COX2 inhibitor, celecoxib, was used to develop novel PDE5 inhibitors. Novel pyrazolines were identified with potent PDE5 inhibitory activity lacking COX2 inhibitory activity. Compound d12 was the most potent with an IC50 of 1 nM, which was three times more potent than sildenafil and more selective with a selectivity index of >10,000-fold against all other PDE

  一种基于配体的方法涉及对源自 COX2 抑制剂塞来昔布的三取代吡唑啉支架进行系统修饰，用于开发新型 PDE5 抑制剂。新型吡唑啉被鉴定为具有有效的 PDE5 抑制活性，但缺乏 COX2 抑制活性。化合物d12是最有效的，其 IC 50为 1 nM，其效力是西地那非的三倍并且更具选择性，选择性指数相对于所有其他 PDE 同工酶 > 10,000 倍。西地那非抑制 PDE5 的全长和催化片段，而化合物d12仅抑制全长酶，表明酶抑制机制不同于西地那非。化合物d12的PDE5抑制活性使用 cGMP 生物传感器测定法在细胞中得到证实。化合物d12的口服给药达到比IC 50值高> 1000 倍的血浆水平，并且在重复给药后没有表现出可辨别的毒性。这些结果揭示了一种以前所未有的效力和同工酶选择性抑制 PDE5 的新策略。
