GDC-0334 (GDC0334) is a highly potent, selective, orally bioavailable TRPA1 antagonist with IC50 of 1.7 nM in cell-based assays.GDC-0334 demonstrated potent TRPA1 inhibition in several species, including human (IC50=1.7 nM), cynomolgus (IC50=3.6 nM), mouse (IC50=2.7 nM), guinea pig (IC50=11.1 nM), and dog (IC50=102 nM).GDC-0334 displays good selectivity against human TRPV1, TRPM8, and TRPC6 (all IC50s>10 uM).GDC-0334 also inhibits calcium flux in human primary cells, HASMCs and HLFs, treated with the TRPA1 agonist AITC.GDC-0334 suppresses AITC-induced edema in vivo in rat (1-10 mg/kg), reduces OVA-induced asthma model in rats and guinea pigs and guinea pig model of cough.GDC-0334 is a potent inhibitor of AITC-induced dermal blood flow (DBF) in vivo in rats and guinea pigs, reduces AITC-induced perfusion and nocifensive behavior in rats and itch and pain scores in humans.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C.
