Development of Highly Selective Aldosterone Synthase Inhibitors

Recent clinical studies have heralded aldosterone synthase inhibitors (ASIs) as a promising therapeutic option for managing resistant hypertension. The efficacy of these compounds is believed to stem from their ability to mitigate aldosterone production. Consequently, we delved into the potential of aldosterone synthase inhibition as a therapeutic strategy for patients with refractory hypertension. Our focus is on the synthesis and optimization of innovative heterocyclic compounds that exhibit aldosterone synthase inhibitory activity. The CYP11B2 inhibitor we have developed exhibits an encouraging pharmacokinetic (PK) profile, along with a robust pharmacokinetic-pharmacodynamic (PK-PD) relationship. This has enabled us to meticulously evaluate the trends in aldosterone inhibition and assess the compound's efficacy in vivo using nonhuman primate models.
