Nepicastat Hcl(SYN117 Hcl; RS-25560-197 Hcl) is a dopamine beta-hydroxylase inhibitor with IC50 of 8.5 ± 0.8 and 9.0 ± 0.8 nM for bovine and human, respectively. IC50 value: 8.5/9.0 nM(bovine/human dopamine beta-hydroxylase)Dopamine beta-hydroxylase is an enzyme that catalyzes the conversion of dopamine to norepinephrine. Nepicastat (SYN117; RS-25560-197) has been studied as a possible treatment for congestive heart failure, and appears to be well tolerated as such.
