2-APB is a transient receptor potential (TRP) activator. The compound also directly blocks the mitochondrial permeability transition pore, sarco/endoplasmic reticulum Ca2+-ATPase pumps, and native store operated channels, as well as other ion channels. 2-APB does not activate the subfamily transient receptor potential vanilloids (TRPVs) TRPV4, TRPV5, and TRPV6, but can activate VR1 (TRPV1), VRL-1 (TRPV2), and TRPV3. 2-ABP was first used as an inhibitor of IP3R (inositol 1,4,5-triphosphate receptor) with the ability to permeate the membrane. 2-ABP can induce Ca2+entry without activating exocytosis. In pancreatic acinar cells 2-ABP can inhibit calcium mobilization. 2-APB is an activator of Orai3.用于黄酮类化合物的密度测定。膜渗透调控因子，调控细胞间IP3诱导的钙离子释放。
