The synthesis and phosphodiesterase (PDE) inhibitory profile of a series of imidazopyridines, including sulmazole and isomazole, on separated PDE isoenzymes are described. The results show that both sulmazole and isomazole are weak inhibitors of PDE III, and their inotropic activity is unlikely to be due to PDE III inhibition alone. Surprisingly, both compounds were found to be significant inhibitors
描述了一系列咪唑并吡啶(包括舒马唑和异唑)对分离的PDE同工酶的合成和磷酸二酯酶(PDE)抑制谱。结果表明,舒马唑和异咪唑都是PDE III的弱抑制剂,它们的正性活性不太可能仅由于PDE III的抑制而引起。出乎意料的是,发现这两种化合物都是cGMP特异性同工酶PDE V的重要抑制剂,并且已经制备了一系列简单的2-取代的苯基咪唑并[4,5-b]吡啶用于研究PDE活性的SAR。已显示这对链长,极性和杂原子连接基团的性质敏感。已经确定了有效的PDE V抑制剂,其中许多也是PDE IV的重要抑制剂。
