Catalog Number: 2896
Chemical Name: 2-(1,3-Dimethyl-2,6-dioxo-1,2,3,6-tetrahydro-7H-purin-7-yl)-N-(4-isopropylphenyl)acetamide
Biological Activity
Selective TRPA1 channel blocker that antagonizes AITC- and formalin-evoked calcium influx (IC50 values are 6.2 and 5.3 μM respectively). Does not block currents mediated by TRPV1, TRPV3, TRPV4, hERG or NaV1.2 channels. Inhibits AITC- and formalin-induced flinching in vivo.
