HY-16787

ICA-121431 2 Publications Verification	Sodium Channel	Cardiovascular Disease
ICA-121431 is a nanomolar potent and broad-spectrum voltage-gated sodium channel (Na_v) blocker, shows equipotent selectivity for human Na_v1.1 and Na_v1.3 subtypes with IC₅₀ values of 13 nM and 23 nM, respectively. ICA-121431 shows less potent inhibition of Na_v1.2 (IC₅₀=240 nM) and 1,000 fold selectivity against Na_v1.4, Na_v1.6, and the TTX-resistant human Na_v1.5 and Na_v1.8 channels (IC₅₀s >10 μM).

HY-157802

LTGO-33	Sodium Channel	Neurological Disease
LTGO-33 is a potent and selective voltage-gated sodium channel NaV1.8 inhibitor. LTGO-33 inhibits NaV1.8 in the nM potency range and exhibits over 600-fold selectivity against human NaV1.1-NaV1.7 and NaV1.9. LTGO-33 exhibits state-independent inhibition with similar potencies on channels in the closed and inactivated conformations. LTGO-33 inhibits native TTX-R NaV1.8 currents in non-human primate and human DRG neurons, where it reduces action potential firing. LTGO-33 can be used for pain disorders research .
