Recently, we reported on the development of potent and selective inhibitors of aldosterone synthase (CYP11B2) for the treatment of congestive heart failure and myocardial fibrosis. A major drawback of these nonsteroidal compounds was a strong inhibition of the hepatic drug-metabolizing enzyme CYP1A2. In the present study, we examined the influence of substituents in the heterocycle of lead structures with a naphthalene molecular scaffold to overcome this unwanted side effect. With respect to CYP11B2 inhibition, some substituents induced a dramatic increase in inhibitory potency. The methoxyalkyl derivatives 22 and 26 are the most potent CYP11B2 inhibitors up to now (IC50 = 0.2 nM). Most compounds also clearly discriminated between CYP11B2 and CYP11B1, and the CYP1A2 potency significantly decreased in some cases (e.g., isoquinoline derivative 30 displayed only 6% CYP1A2 inhibition at 2 mu M concentration). Furthermore, isoquinoline derivative 28 proved to be capable of passing the gastrointestinal tract and reached the general circulation after peroral administration to male Wistar rats.
