Dexfadrostat (FAD-286) is a highly selective and potent non-steroidal inhibitor of aldosterone synthase (CYP11B2), with significant suppression of aldosterone production demonstrated in both in vitro and in vivo studies. It exhibits an IC₅₀ of approximately 4.2 nM for human CYP11B2, showing over 100-fold selectivity over 11β-hydroxylase (CYP11B1), which is critical for avoiding cortisol suppression. In rodent and primate models, FAD-286 effectively reduced plasma aldosterone levels without markedly affecting cortisol or corticosterone, confirming its potential utility in treating conditions such as primary aldosteronism, hypertension, and heart failure driven by aldosterone excess.
