General description
A cell-permeable modulator of Ins(1,4,5)P3-induced Ca2+ release. Inhibits Ins(1,4,5)P3-induced Ca2+ release from rat cerebellar microsomal preparations (IC50 = 42 µM) without affecting [3H]-Ins(1,4,5)P3 binding to its receptor. Does not affect Ca2+ release from the ryanodine-sensitive Ca2+ store in rat leg skeletal muscle and heart. Inhibits spontaneous as well as the phasic contractions induced by uterotonic agents. Also reported to inhibit angiotensin II-induced contractions in aortic muscles.
A cell-permeable modulator of Ins(1,4,5)P3-induced Ca2+ release. Inhibits Ins(1,4,5)P3-induced Ca2+ release from rat cerebellar microsomal preparations (IC50 = 42 µM) without affecting [3H]-Ins(1,4,5)P3 binding to its receptor. In liver cells, 2-APB inhibits store-operated Ca2+ channels through a mechanism which may involve its binding to either the channel protein or an associated regulatory protein. Has no effect on the Ca2+ release from the ryanodine-sensitive Ca2+ store prepared from rat leg skeletal muscle and heart.
