Submit ReviewPNU 37883 hydrochloride is a 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.
PNU 37883 hydrochloride is also offered as part of the Tocriscreen 2.0 Max. 了解 Tocris 化合物库的更多信息。

PNU 37883 was used to understand whether it shows BK channel blocking effect. The product worked ideally although inhibition data obtained from the product shows variation.
I suggest using an alternate channel blocker to measure blocking action to identify the variation with PNU 37883.
