Abstract
Abstract Retinoid like activity is exhibited by compounds of the formula ##STR1## wherein the R 1 -R 7 groups are independently H or straight chain or branched chain lower alkyl or cycloalkyl of 1 to 6 carbons; X symbolizes an ester or thioester linkage, Y is cycloalkyl or branched chain alkyl of 1 to 6 carbons or is (CH 2 ) where n is an integer between 0 to 6 or is an alkenyl group of 2 to 6 carbons, or an alkynyl group of 2 to 6 carbons; and Z is H, OH, OR', OCOR', --COOH or a pharmaceutically acceptable salt, ester or amide thereof, --CH 2 OH or an ether or ester derivative, or --CHO or an acetal derivative, or --COR' or a ketal derivative where R' is an alkyl, cycloalkyl or alkenyl group containing 1 to 6 carbons, or a phenylalkyl, phenyl or substituted phenyl group.
