Optimization of Chromeno[2,3-<i>c</i>]pyrrol-9(2<i>H</i>)-ones as Highly Potent, Selective, and Orally Bioavailable PDE5 Inhibitors: Structure–Activity Relationship, X-ray Crystal Structure, and Pharmacodynamic Effect on Pulmonary Arterial Hypertension
To further explore the structure–activityrelationship around the chromeno[2,3-c]pyrrol-9(2H)-one scaffold, 19 derivatives as inhibitors against PDE5 were discovered. The most potent inhibitor 3 has an IC50 of 0.32 nM with remarkable selectivity and druglike profile. Oral administration of 3 (1.25 mg/kg) caused comparable therapeutic effects to sildenafil (10.0 mg/kg) against pulmonary arterial hypertension
