摘要:Pyridine Substituted 3,4-Dihydro-1H-Quinolin-2-Ones (E.G.,1-3) Constitute A Class Of Highly Potent And Selective Inhibitors Of Aldosterone Synthase (Cyp11B2),A Promising Target For The Treatment Of Hyperaldosteronism,Congestive Heart Failure,And Myocardial Fibrosis. Among These,Ethyl-Substituted 3 Possesses High Selectivity Against Cyp1A2. Rigidification Of 3 By Incorporation Of The Ethyl Group Into A 5-Or 6-Membered Ring Affords Compounds With A Pyrroloquinolinone Or Pyridoquinolinone Molecular Scaffold (E.G.,4 And 5). It Was Found That These Molecules Are Even More Potent And Selective Cyp11B2 Inhibitors Than Their Corresponding Open-Chain Analogues. Moreover,Pyrroloquinolinone 4 Exhibits No Inhibition Of The Six Most Important Hepatic Cyp Enzymes As Well As A Bioavailability In The Range Of The Marketed Drug Fadrozole. The Sar Studies Disclose That Subtle Changes In The Heterocyclic Moiety Are Responsible For Either A Strong Or A Weak Inhibition Of The Highly Homologous 11 Beta-Hydroxylase (Cyp11B1). These Results Are Not Only Important For Fine-Tuning The Selectivity Of Cyp11B2 Inhibitors But Also For The Development Of Selective Cyp11B1 Inhibitors That Are Of Interest For The Treatment Of Cushing'S Syndrome And Metabolic Syndrome.
