Chemical Name:N-(Cyclopropylmethoxy)-3,4,5-trifluoro-2-[(4-iodo-2-met
hylphenyl)amino]-benzamide
Biological Activity:
Potent inhibitor of MEK1/2. Inhibits isolated
enzyme at a concentration of 8 nM and inhibits MEK activity in synovial
fibroblasts at concentrations of 30-100 nM. Highly selective for MEK; IC50
values are > 1, > 4, > 4 and > 10 μM for ERK,
c-Src, cdks and PI 3-kinase γ
respectively. Antihyperalgesic; blocks static allodynia in the streptozocin
model of neuropathic pain following i.t. administration.
