Biological Activity: Vinpocetine is selective for PDE1: IC50 = 21 µM, vs. PDE3: IC50 = 300 µM (bovine heart). Vinpocetine inhibits differently the various subtypes of PDE1 (IC50 from 8 to 50 µm). It is also reported to inhibit PDE7B with an IC50 of 60 µM, and it can have effects on Heat Shock Factor 1 (EC5050 = 195 µM) and ADH-induced lipid peroxidation ( IC50 = 137 µM in rat brain microsome).
CAS Number: 42971-09-5
Description: Vinpocetine, also known as Cavinton or ethyl apovincaminate, is a specific inhibitor of basal and calmodulin-activated PDE1. Also blocks voltage-gated Na+ channels.
