Acetylenes disubstituted with a furyl group and a substituted phenyl group having retinoid like activity

Abstract

Abstract Retinoid like activity is exhibited by compounds of the formula ##STR1## where R 1 -R 3 independently are hydrogen, lower alkyl, cycloalkyl or lower alkenyl, A and B independently are hydrogen, lower alkyl, cycloalkyl, lower alkenyl, SR 4 or OR 4 where R 4 is lower alkyl, cycloalkyl or lower alkenyl; Y is selected from a group consisting of furyl, pyridazinyl, pyrimidinyl, pyrazinyl, thiazolyl or oxazolyl; E is lower alkenyl, lower alkynyl, lower cycloalkyl, lower branched chain alkyl, or is characterized by the formula (CH 2 ) n where n is 0-5, and Z is H, OH, OR 5 , OCOR 5 , --COOH or a pharmaceutically acceptable salt, ester or amide thereof, --CH 2 OH, CH 2 OR 6 , CH 2 OCOR 6 , or --CHO, CH(OR 7 ) 2 , CHOR 8 O, or COR 9 , CR 9 (OR 7 ) 2 , CR 9 OR 8 O where R 5 is lower alkyl, phenyl or lower alkylphenyl, R 6 is lower alkyl, phenyl or lower alkylphenyl, R 7 is lower alkyl, R 8 is a divalent alkyl radical of 2-5 carbons, and R 9 is an alkyl, cycloalkyl or alkenyl group containing 1 to 5 carbons.
