2,5-dimethyl Celecoxib is a derivative of celecoxib that does not inhibit COX-2 (IC50 = >100 μM).1 It does inhibit microsomal prostaglandin E synthase-1 (mPGES-1) in HeLa cells (IC50 = 15.6 μM) and reduces prostaglandin E2 production in HeLa, A549, and HCA-7 cells (IC50s = 0.64, 0.83, and 3.08 μM, respectively).2 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.3 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.2References1. Zhu, J., Song, X., Lin, H.-P., et al.
