2-Aminoethyl diphenylborinate

2-Aminoethyl diphenylborinate (2-APB) is a cell-permeable inhibitor of Inositol triphosphate receptor (IP3R). 2-Aminoethyl diphenylborinate also inhibits the store-operated Ca2+ (SOC) channel and activates some TRP channels (V1, V2 and V3). Additionally, 2-Aminoethyl diphenylborinate has inhibitory effects on vasospasm. At high concentrations, it exhibits specific anti-inflammatory and antioxidant effects in neural tissue[1][2][3][4][5].
