AM-001
Based on 1 Customer Validation
AM-001 is a selective Epac1 inhibitor with an IC50 value of 47.8-53.7 μM. AM-001 blocks cAMP (Cyclic AMP) (HY-B1511)-induced conformational changes of Epac1, inhibits Epac1-dependent activation of Rap1, and does not compete with cAMP for binding to Epac1. AM-001 disrupts the formation of the Epac1-GRK5 complex, blocks nuclear import of GRK5, and inhibits GRK5-mediated nuclear export of HDAC5 and activation of MEF2. AM-001 can be used in research related to heart disease, myocardial ischemia/reperfusion injury, SARS-CoV-2 infection, influenza A virus infection, atrial fibrillation and idiopathic pulmonary fibrosis.

EPAC1 47.8-53.7 μM (IC50) |
AM-001 (1-1000 μM) acts as a non-competitive inhibitor of Epac1 in the CAMYEL BRET sensor assay, with an IC50 of 53.7 μM, reducing maximal cAMP (Cyclic AMP) (HY-B1511)-induced conformational changes without affecting cAMP binding affinity[1].
