potent and selective PDE5 inhibitors. Compound 6 has been identified as a more potent and selective PDE5 inhibitor than sildenafil (1). It is as efficacious as sildenafil in in vitro and in vivo PDE5 inhibition models, and it is orally bioavailable in rats and dogs. The superior isozyme selectivity of 6 is expected to exert less adverse effects in humans when used for erectile dysfunction treatment.
已经制备了新型的吡唑并吡咯并哒嗪衍生物作为有效的和选择性的PDE5抑制剂。与西地那非(1)相比,化合物6被确定为更有效和更具选择性的PDE5抑制剂。在体外和体内PDE5抑制模型中,它的作用与西地那非一样,并且在大鼠和狗中都具有口服生物利用度。当用于勃起功能障碍治疗时,优越的6同工酶选择性有望对人类产生较少的不良影响。
