Ordering Information

Biological Activity

(R)-Nepicastat HCl is a potent and selective dopamine-β-hydroxylase inhibitor, demonstrating inhibitory activity against bovine dopamine-β-hydroxylase (IC50 25.1 nM) and human dopamine-β-hydroxylase (IC50 18.3 nM). By inhibiting dopamine-β-hydroxylase, the enzyme responsible for converting dopamine to norepinephrine, the compound disrupts catecholamine biosynthesis. This inhibition decreases tissue norepinephrine levels while elevating dopamine concentrations, thereby attenuating sympathetic neurotransmission and modulating downstream cardiovascular and neurochemical signaling pathways.

FAQ
Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
  • Preheat media/saline to 37°C.
  • Mix rapidly (pipette/vortex) upon addition.
  • For complex mixes, always add the aqueous phase last.
  • Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
