AMG8379 

Cat. No.: HY-108425
Handling Instructions

AMG8379 is a potent, orally active and selective sulfonamide antagonist of the voltage-gated sodium channel NaV1.7, with IC50s of 8.5 and 18.6 nM for hNaV1.7 and mNaV1.7, respectively. AMG8379 potently and reversibly blocks endogenous Tetrodotoxin (TTX)-sensitive sodium channels in dorsal root ganglia (DRG) neurons with an IC50 of 3.1 nM.

Description

AMG8379 is a potent, orally active and selective sulfonamide antagonist of the voltage-gated sodium channel NaV1.7, with IC50s of 8.5 and 18.6 nM for hNaV1.7 and mNaV1.7, respectively. AMG8379 potently and reversibly blocks endogenous Tetrodotoxin (TTX)-sensitive sodium channels in dorsal root ganglia (DRG) neurons with an IC50 of 3.1 nM[1].

In Vitro

AMG8379 is 100 to 1000-fold selective over other NaV family members, including NaV1.4 expressed in muscle and NaV1.5 expressed in heart, as well as TTX-resistant NaV channels in DRG neurons[1].
The IC50 for AMG8379 inhibition of C-fiber spiking based on the level of firing in NaV1.7 KO mice representing complete pharmacological block of the NaV1.7-component of this assay is calculated. In this manner, the IC50 for AMG8379 block is 47.0 ± 8.1 nM[1].

In Vivo

AMG8379 (30-100 mg/kg; p.o.) inhibits Capsaicin-induced nociceptive behavior[1].

Animal Model: CD-1 male mice[1]
Dosage: 30 or 100 mg/kg body weight
Administration: Oral
Result: Showed a dose-dependent reduction in overall nociceptive behavior.
