Pricing Availability Delivery Time Qty
Cat.No. 2095 - PNU 37883 hydrochloride | C21H35N3O.HCl | CAS No. 57568-80-6
Description: Vascular Kir6 (KATP) channel blocker
Chemical Name: N-Cyclohexyl-N'-tricyclo[,7]dec-1-yl-4-morpholinecarboximidamide hydrochloride
Purity: ≥99% (HPLC)

Biological Activity

Novel antagonist selective for the vascular form of Kir6 (KATP) channel; inhibits Kir6 currents in isolated mesenteric artery smooth muscle cells (Kd = 65 nM) but not in cardiac or skeletal myocytes. Inhibits blood vessel relaxation and hypotension induced by pinacidil in vivo. Displays weak diuretic effects.
