Biological Data

Biological description

2-APB is a membrane permeable IP3 (inositol 1,4,5-trisphosphate) receptor antagonist (IC50 = 42µM) and store-operated Ca2+ channel (SOC) antagonist.


2-APB also blocks SERCA (IC50 = 91µM) and modulates some TRP channels (inhibits TRPC1, TRPC3 and TRPC5, activates TRPV1, TRPV2 and TRPV3 and shows dual activity on TRPM7 channels).


2-APB is an effector of store-operated Ca2+ entry (SOCE) which potentiates store-operated Ca2+ entry at 1-5 µM and inhibits it at >30 µM.


2-APB has also been shown to increase excitability in pyramidal neurons.
