  Novel Selective Hindlimb Vasodilators:  Synthesis and Biological Activity of 1-Acyl-4-aminopiperidine Derivatives

  摘要：

  A series of 6-(4-amino-1-piperidinyl)carbonyl-2(1H)-quinolinones, and their open form derivatives, were synthesized and evaluated for their ability to stimulate femoral artery blood flow (FBF) in the canine hindlimb. All members of this series stimulated FBF, and subsequent experiments revealed that selected members of this series produced minimal changes in coronary blood flow or systemic blood pressure. Compound 25 was the most promising agent in this respect, and clinical trials are now ongoing to evaluate the effectiveness of this drug as a novel treatment for intermittent claudication and Raynaud's phenomenon.
