MEK inhibitors: The chemistry and biological activity of U0126, its analogs, and cyclization products
摘要:
In search of antiinflammatory drugs with a new mechanism of action, U0126 was found to functionally antagonize AP-1 transcriptional activity via noncompetitive inhibition of the dual specificity kinase MEK with, an IC50 of 0.07 mu M for MEK 1 and 0.06 mu M for MEK 2. U0126 can undergo isomerization and cyclization reactions to form a variety of products, both chemically and in vivo, all of which exhibit less affinity for MEK and lower inhibition of AP-1 activity than parent, U0126.
