potent and selectivePDE5inhibitors. Compound 6 has been identified as a more potent and selectivePDE5inhibitor 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 erectiledysfunctiontreatment.
