产品描述

2-APB is an antagonist of Ins(1,4,5) P3-induced Ca2+ release with IC50 value of 42 μM [1].

Myo-Ins(1,4,5) P3 receptors (IP3R) mediates the mobilization of internal Ca2+. IP3R is involved in Ca2+ waves and Ca2+ oscillations.

2-APB is an antagonist of Ins(1,4,5) P3-induced Ca2+ release. 2APB inhibited Ins(1,4,5)-P3-induced Ca2+ release from rat cerebellar microsomal with IC50 value of 42 μM. Addition of 2APB to the extracellular inhibited the cytosolic Ca2+ rise in human platelets and neutrophils stimulated by thrombin. Also, 2APB inhibited the contraction of thoracic aorta induced by angiotensin II (AII) [1]. In HEK-293 cells, 2-APB in the extracellular blocked human TRPC5 channels with IC50 value of 20 μM. Also, 2-APB blocked TRPC6 and TRPM3. In cells overexpressing TRPC5, 2-APB inhibited cell proliferation [2]. In the mouse pancreatic acinar cell, 2-APB significantly inhibited store-operated Ca2+ (SOC)-mediated Ca2+ entry at low concentrations. In permeabilized acinar cell, 2-APB inhibited direct stimulation of Ca2+ release and InsP3-induced Ca2+ release at high concentrations [3].

In rats with I/R-induced testicular injury, 2-APB significantly increased superoxide dismutase (SOD), total antioxidant capacity (TAC) and glutathione (GSH) and reduced malondialdehyde (MDA) and DNA fragmentation, which suggested the antiapoptotic and antioxidative effects of 2-APB [4].
