  Design and synthesis of furyl/thineyl pyrroloquinolones based on natural alkaloid perlolyrine, lead to the discovery of potent and selective PDE5 inhibitors

  摘要：

  Based on perlolyrine (1), a natural alkaloid with weak PDE5 potency from the traditional Chinese aphrodisiac plant Tribulus terrestris L., a series alpha-substituted tetrahydro-beta-carboline (TH beta C) derivatives were synthesized via T(+)BF4(-)-mediated oxidative C-H functionalization of N-aryl TH beta Cs with diverse potassium trifluoroborates. Following Winterfeldt oxidation afforded the corresponding furyl/thienyl pyrroloquinolones, of which 5-ethylthiophene/ethylfuran derivatives 20a-b were identified as the most potent and selective PDE5 inhibitors. Among the enantiomers, (S)-20a and (S)-20b (IC50 = 0.52 and 0.39 nM) were found to be more effective than their (R)-antipode, display favorable pharmacokinetic profiles, exert in vitro vasorelaxant effects on the isolated thoracic aorta, and exhibit in vivo efficacy in the anesthetized rabbit erectile model.
