Description: 2,5-dimethyl Celecoxib is a derivative of celecoxib that does not inhibit COX-2. It does inhibit microsomal prostaglandin E synthase-1 (mPGES-1) and reduces prostaglandin E2 (PGE2) production in HeLa, A549, and HCA-7 cells. It inhibits proliferation of drug-sensitive RPMI8226 and multidrug-resistant 8226/Dox40 multiple myeloma cells, as well as increases the rate of apoptosis when used at concentrations of 20 and 30 µM. 2,5-dimethyl Celecoxib reduces the expression of survivin, cyclin A, cyclin B, MEK1, and MEK2 in 8226/Dox40 cells. The antiproliferative effect of 2,5-dimethyl celecoxib is independent of mPGES-1 inhibition.
