摘要

Retinold-like activity is exhibited by compounds of the formula <IMAGE> where X is S, O; R1, R2 and R3 are hydrogen or lower alkyl; R4 and R5 are hydrogen or lower alkyl with the proviso that R4 and R5 cannot both be hydrogen, R6 is hydrogen, lower alkyl, lower alkenyl, lower cycloalkyl or halogen; n is 0-5, and B is H, -COOH or a pharmaceutically acceptable salt, ester or amide thereof, -CH2OH or an ether or ester derivative, or -CHO or an acetal derivative, or -COR1 or a ketal derivative where R1 l is -(CH2)mCH3 where m is 0-4, or a pharmaceutically acceptable salt thereof.
