Chemical Name: 2-Aminoethoxydiphenylborane

Biological Activity

A functional and membrane permeable D-myo-inositol 1,4,5-trisphosphate (IP3) receptor antagonist (IC50 = 42 μM). Stimulates store-operated calcium (SOC) release at low concentrations (< 10 μM) and inhibits it at higher concentrations (up to 50 μM). Increases STIM-Orai channel conductance and limits ion selectivity. Modulator of TRP channels; blocks TRPC1, TRPC3, TRPC5, TRPC6, TRPV6, TRPM3, TRPM7, TRPM8 and TRPP2 and at higher concentrations stimulates TRPV1, TRPV2 and TRPV3. Also blocks specific gap channel subtypes.
