Description

MRS1845 is a selective store-operated calcium (SOC) channel inhibitor with an IC50 of 1.7 μM[1]. MRS1845 is an ORAI1 inhibitor[2][3].

IC50 & Target

Ca2+ channel[1]

In Vitro

Treatment with MRS1845 (10 μM) virtually disrupts the effects of β-glycerophosphate on store-operated Ca2+ entry (SOCE)[2].
MRS1845 (10 μM) significantly decreases SOCE and virtually abolishes the increase of SOCE following placental growth factor (PlGF) treatment[3].
