A novel class of nonantioxidant dual inhibitors of both CO and 5-LO is described. The balance between the activity against CO and 5-LO can be shifted by modifying the substitution pattern of the phenyl moiety at the 6-position of the pyrrolizine ring. Structure-activity relationships are discussed. Compound 3e with a 4-Cl substituent (IC50 = 0.21 microM (CO); 0.18 microM (5-LO)) and 3n with a 4-OCH3

We synthesized and evaluated inhibitors for the microsomalprostaglandinE2synthase-1 (mPGES-1), based on the arylpyrrolizine scaffold. In a cell free mPGES-1 assay several “sulfonimides” exceeded our lead ML3000 (3) in potency. The most promising compound, the tolylsulfonimide 11f, revealed an IC50 of 2.1 μM and is equipotent to the literature reference molecule MK886 (1). Selected compounds also
