PNU 37883 hydrochloride
Based on 1 Customer Validation
PNU 37883 hydrochloride (PNU 37883A) is a selective vascular ATP-sensitive potassium (Kir6, KATP) channels blocker. PNU 37883 hydrochloride has diuretic effects with specific binding in kidney and vascular smooth muscle rather than in brain or pancreatic beta cells.

Biological Activity
In HEK-293 cells stably expressing Kir6.2/SUR1, Kir6.2/SUR2A, Kir6.2/SUR2B or Kir6.1/SUR2B, PNU-37883A inhibits four types of KATP channels, but to different extents. Inhibition of the putative smooth muscle KATP channel types, Kir6.2/SUR2B (IC50 of 15 μM) and Kir6.1/SUR2B (IC50 of 6 μM). PNU-37883A significantly inhibits currents generated by expressing Kir6.2Δ26 alone, with an IC50 of 5 μM, which was significantly increased to 38 μM when Kir6.2Δ26 is expressed with SUR2B[1].
PNU 37883 (0.1-10 nM) hydrochloride produces a concentration-dependent attenuation of the relaxation of agmatine (100 μM) in phenylephrine- or KCl- precontracted aortic rings. However, treatment with PNU 37883 (10 nM) hydrochloride alone does not modify the vascular tone[3].
