KRN 4884 is an opener of the K+ channel. KRN 4884 (0.1-3 μM) activates KATP channels in a concentration-dependent manner (EC50=0.55 μM), in the presence of intracellular ATP (1 mM).
Tifenazoxide is an effective and SUR1/Kir6.2 selective KATP channels opener. Tifenazoxide has an anti-diabetic effect, can inhibit glucose-stimulated insulin release in vitro and in vivo.
AMP-PNP tetralithium(Adenylyl-imidodiphosphate tetralithium)是一种不可水解的 ATP 类似物,可完全占据 ATP 结合位点而不发生酶促水解,从而为解析 ATP 依赖性生物过程提供稳定且可控的实验条件。AMP-PNP 广泛用于研究酶活性、激酶调控、DNA 和 RNA 代谢、离子通道功能以及蛋白复合体组装等生化和结构生物学研究。
