Assignee: Allergan Sales, Inc. (Irvine, CA)
Filing Date:Feb 25, 1998
Application Number:09/030,351
Claims:1. A method of treating a mammal afflicted with a condition or disease which is susceptible to treatment by a therapeutic agent having retinoid-like activity, the process comprising administering to said mammal an effective dose of a pharmaceutical composition including a pharmaceutically acceptable excipient and a compound of the formula ##STR11## wherein R.sub.1 and R.sub.2, independently are n-alkyl groups having 2 to 8 carbons, or cyclo or branch-chained alkyl groups of 3 to 8 carbons;

R.sub.3 is hydrogen or lower alkyl;

X is S, 0 or N-R.sub.4 where R.sub.4 is hydrogen or lower alkyl;

Y is a heteroaryl group selected from a group consisting of pyridyl, thienyl, furyl, pyridazinyl, pyrimidinyl, and pyrazinyl;

A is (CH.sub.2).sub.n where n is 0-5, lower branched chain alkyl having 3 to 6 carbons, cycloalkyl having 3 to 6 carbons, alkenyl having 2 to 6 carbons and 1 or 2 double bonds, alkynyl having 2 to 6 carbons and 1 or 2

triple bonds;

B is hydrogen, COOH or a pharmaceutically acceptable salt thereof, COOR.sub.5, CONR.sub.6 R.sub.7, --CH.sub.2 OH, CH.sub.2 OR.sub.8, CH.sub.2 COR.sub.8, CHO, CH(OR.sub.9).sub.2, CHOR.sub.10 O, --COR.sub.11, CR.sub.11 (OR.sub.9).sub.2, or CR.sub.11 OR.sub.10 O, where R.sub.5 is an alkyl group of 1 to 10 carbons, or a cycloalkyl group of 5 to 10 carbons, or R.sub.5 is phenyl or lower alkylphenyl, R.sub.6 and R.sub.7 independently are hydrogen, an alkyl group of 1 to 10 carbons, or a cycloalkyl group of 5 to 10 carbons, or phenyl or lower alkylphenyl, R.sub.8 is alkyl of 1 to 10 carbons, phenyl or lower alkylphenyl, R.sub.9 is lower alkyl, R.sub.10 is divalent alkyl radical of 2-5 carbons and R.sub.11 is an alkyl, cycloalkyl or alkenyl group containing 1 to 5 carbons.
