Abstract

Abstract Compositions for inhibiting protein kinase C, comprising an inhibitory amount of a compound having the formula: ##STR1## wherein Q is a hydrophobic group; wherein X is --CH 2 --CH 2 -- or --CH═CH--, which may be substituted by one or more halogens or C 1 -C 3 alkyl groups, wherein Y is ##STR2## wherein W is a halogen; wherein R 1 and R 2 may be the same or different and are selected from hydrogen, lower alkyl groups having from 1 to 7 carbon atoms, aralkyl, and aryl groups, and wherein Z is a phosphate or an organic group, and a pharmaceutically acceptable carrier material; and a method for inhibiting protein kinase C using such compositions.
