The present invention relates to derivatives of tadalafil, substituted with fluorine on the methylene carbon atom situated between the oxygens of the benzodioxol ring, and optionally further substituted with deuterium atoms in place of normally abundant hydrogen, and
13
C in place of normally abundant
12
C. These compounds are selective PDE5 inhibitors and possess advantageous biopharmaceutical and pharmacokinetic properties. The invention further provides compositions comprising these compounds and methods of treating diseases and conditions that are responsive to PDE5 inhibition, alone and in combination with additional agents.
本发明涉及替代他达拉非的衍生物,在苯并二氧杂环戊二烷环的氧原子之间的亚甲基碳原子上取代氟,并且可选地进一步用氘原子取代正常丰富的氢,以及用13C取代正常丰富的12C。这些化合物是选择性的PDE5抑制剂,并具有有利的生物制药和药代动力学性质。该发明还提供了包含这些化合物的组合物和治疗对PDE5抑制有响应的疾病和症状的方法,单独或与其他药物联合使用。
