Immunopharmacology Comments
Inhibition of mPGES-1 is proposed as a potentially safer alternative to COX-2 inhibition for the treatment of pain and inflammation, with a reduced risk of cardiovascular side effects [4]. Inhibition of mPGES-1 in A549 cells and mouse macrophages by compound III [PMID: 24045148] reduces PGE2 production [2].
