Selective Orai1 and SOCE (store-operated Ca2+ entry) potentiator that marginally affects Orai2 and Orai3.
Orai1 Agonist IA65 is a selective Orai1 and SOCE (store-operated Ca2+ entry) potentiator that preferentially occupies Oari1 N-terminal domain binding pocket and significantly enhances Orai1-mediated Ca2+-influx and concurrently potentiates Orai1 Ca2+-dependent inactivation (CDI) with an EC50 of 1.9 uM. IA65 mildly potentiates ORAI3-mediated ICRAC with a slight inhibition of ICRAC mediated by ORAI2. Increases Orai1 activity in VSMCs and skeletal muscle fibers in a concentration-dependent manner. IA-65 is shown to be inactive against TRPV1, TRPM8, or CaV2.2 and nontoxic up to 100 uM.
