Phosphodiesterase 5 (PDE5) inhibitors have been used as clinical agents to treat erectile dysfunction and pulmonary arterial hypertension (PAH). Herein, we detail the discovery of a novel series of chromeno[2,3-c]pyrrol-9(2H)-one derivatives as selective and orally bioavailable inhibitors against phosphodiesterase 5. Medicinal chemistry optimization resulted in 2, which exhibits a desirable inhibitory
磷酸二酯酶5(PDE5)抑制剂已用作治疗勃起功能障碍和肺动脉高压(PAH)的临床药物。在本文中,我们详细介绍一系列新的色烯的发现[2,3- c ^ ]吡咯9(2 ħ) -酮衍生物作为选择性和口服生物可利用的抑制剂对磷酸二酯酶5药物化学优化导致了2,其表现出理想的抑制力为5.6 nM,具有显着的选择性以及出色的药代动力学特性和63.4%的口服生物利用度。另外,口服2与10.0 mg / kg的柠檬酸西地那非相比,以5.0 mg / kg的剂量对mPAP(平均肺动脉压)和RVHI(右心室肥大指数)的药效学效果更好。这些活性及其合理的类药物特性,例如人肝微粒体稳定性,细胞色素抑制作用,hERG抑制作用和药理安全性,表明2是治疗PAH的潜在候选者。
