Abstract

The present invention relates to COX-2 inhibitors of the formula: ##STR1## wherein, A=halogen, C.sub.1 -C.sub.6 alkyl, SR.sup.1 or OR.sup.1 ; PA1 B=O, or H,H; PA1 X=Br or Cl; PA1 L=5-,6- or 7-membered heteroatom containing rings and is preferrably a 5-membered heteroaromatics such as thiazole, oxazole, imidazole, or oxadiazole; PA1 n=1-6, wherein the (C) is optionally branched; PA1 R=optionally substituted aryl wherein aryl is selected from phenyl, pyridyl, naphthyl, benzothienyl, or quinoxolyl, alkyl, carboxyl, esters, amino, amide, or urea; and PA1 R.sup.1 =alkyl. The compounds are useful as research tools and could be useful as potential therapeutic agents in the inhibition of the PGHS-2 isozyme and in the treatment of inflammation in mammals including humans or other conditions associated with the production of prostaglandins.
