Retinold like activity is exhibited by compounds of the formula ##STR1## where R.sub.1 -R.sub.3 independently are hydrogen, lower alkyl, cycloalkyl or lower alkenyl, A and B independently are hydrogen, lower alkyl, cycloalkyl, lower alkenyl, SR.sub.4 or OR.sub.4 where R.sub.4 is lower alkyl, cycloalkyl or lower alkenyl; Y is pyridyl; E is lower alkenyl, lower alkynyl, lower cycloalkyl, lower branched chain alkyl, or is characterized by the formula (CH.sub.2).sub.n where n is 0-5, and Z is H, OH, OR.sub.5, OCOR.sub.5, --COOH or a pharmaceutically acceptable salt, ester or amide thereof, --CH.sub.2 OH, CH.sub.2 OR.sub.6, CH.sub.2 OCOR.sub.6, or --CHO, CH(OR.sub.7).sub.2, CHOR.sub.8 O, or COR.sub.9, CR.sub.9 (OR.sub.7).sub.2, CR.sub.9 OR.sub.8 O where R.sub.5 is lower alkyl, phenyl or lower alkylphenyl, R.sub.6 is lower alkyl, phenyl or lower alkylphenyl, R.sub.7 is lower alkyl, R.sub.8 is a divalent alkyl radical of 2-5 carbons, and R.sub.9 is an alkyl, cycloalkyl or alkenyl group containing 1 to 5 carbons.
A compound of the formula ##STR16## wherein R.sub.1 -R.sub.3 independently are hydrogen, lower alkyl, cycloalkyl or lower alkenyl, A and B independently are hydrogen, lower alkyl, cycloalkyl, lower alkenyl, SR.sub.4 or OR.sub.4 where R.sub.4 is lower alkyl, cycloalkyl or lower alkenyl;
A compound of the formula ##STR17## wherein A and B and R.sub.1 -R.sub.3 independently are hydrogen, lower alkyl, cycloalkyl or lower alkenyl, with the proviso that one of A and B is not hydrogen;
A compound of the Formula ##STR18## wherein R.sub.1 -R.sub.3 independently are hydrogen, lower alkyl, cycloalkyl or lower alkenyl, A and B independently are hydrogen, lower alkyl, cycloalkyl, lower alkenyl, or SR.sub.4 where R.sub.4 is lower alkyl, cycloalkyl or lower alkenyl, with the proviso that one of A and B is SR.sub.4 ;
A compound of the Formula ##STR19## wherein A and B are hydrogen, lower alkyl, cycloalkyl or lower alkenyl, with the proviso that one of A and B is not hydrogen, and
A compound of the Formula ##STR20## wherein A and B independently are hydrogen, lower alkyl, cycloalkyl, lower alkenyl, or SR.sub.4 where R.sub.4 is lower alkyl, cycloalkyl or lower alkenyl, with the proviso that one of A and B is SR.sub.4, and
