MedKoo CAT#: 522583
CAS#: 313254-51-2
Description: ICA-121431 is a potent, selective inhibitor of the human Nav1.3 and Nav1.1 voltage gated sodium channels (IC50 = 19 nM) with little or no activity against human Nav1.5 or Nav1.7 channels. Voltage-gated sodium channels initiate action potentials in brain neurons, and sodium channel blockers are used in therapy of epilepsy.
