Application

Nepicastat hydrochloride has been used as an inhibitor of dopamine β-hydroxylase (DBH) in zinc finger protein 521 (ZFP521) deficient mice.

Biochem/physiol Actions

By inhibiting dopamine β-hydroxylase (DβH), nepicastat enhances dopamine levels and norepinephrine levels in brain.
Nepicastat is a potent and selective dopamine β-hydroxylase inhibitor with an IC50 of 9 nM and negligible affinity (>10 μM) for twelve other enzymes and thirteen neurotransmitter receptors tested. Nepicastat has been shown to attenuate multiple aspects of cocaine-seeking behavior and suppress cocaine-primed reinstatement of cocaine seeking in rats, and has been in clinical trials for cocaine dependence. Nepicastat also suppressed chocolate self-administration and reinstatement of chocolate seeking in rats.

Previously, we reported that mice deficient in most of the Zfp521 coding region (Zfp521Δ/Δ mice) displayed abnormal behaviors, including hyperlocomotion and lower anxiety. In this study, we aimed to elucidate the involvement and mechanisms of monoamine variation. First, we compared

In the present study, we tested the hypothesis that the potent and selective dopamine-β-hydroxylase (DβH) inhibitor nepicastat would have minimal effects on cardiovascular and pharmacokinetic parameters associated with cocaine administration and would reduce the positive subjective effects produced by cocaine.
