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.
本发明涉及取代了苯并二氧杂环环上氧原子之间的亚甲基碳原子的他达拉非衍生物,且可选择在通常丰富的氢原子位置上进一步取代氘原子和13C代替通常丰富的12C。这些化合物是选择性PDE5抑制剂,具有有利的生物制药和药代动力学特性。本发明还提供了包含这些化合物的组合物和用于治疗对PDE5抑制有反应的疾病和病症的方法,单独或与其他药物组合使用。
