Abstract
Abstract Furanone derivatives of formula (I) wherein R 1 is a C 8 -C 24 straight or branched chain monovalent hydrocarbon radical containing a total of 0-6 double and triple bonds; or a group of the formula where n is 0 or 1 and M is -CHO or -CH 2 0H; or R-alk-where alk is a C 2 -C 12 straight or branched chain monovalent hydrocarbon radical containing 0-2 double and triple bonds and R is naphthalenyloxy or benzylphenoxy, inhibit phosphalipidase A 2 and are useful antiinflammatory and ' antiallergy agents.
