A series of high affinity retinoic acid receptor (RAR) antagonists were prepared based upon the known antagonist AGN 193109 (2). Introduction of various phenyl groups revealed a preference for substitution at the para- position relative to the meta-site. Antagonists with the highest affinities for the RARs possessed hydrophobic groups, however, the presence of polar functionality was also well tolerated.

The present invention relates to a compound of formula STR1 or a nontoxic pharmaceutically acceptable salt, physiologically hydrolyzable ester or solvate thereof, in which X is --O--CO--, --NH--CO--, --CS--NH--, --CO--O--, --CO--NH--, --COS--, --SCO--, --SCH2 --, --CH2 --CH2 --, --C C--, --CH2 --NH--, --COCH2 --, --NHCS--, --CH2 S--, --CH2 O--, --OCH2 --, --NHCH2 -- or --CR5 =CR6 --; Rm and Rk are independently hydrogen, halogen, C1-6 alkyl, hydroxy, C1-6 alkyloxy or nitro; n is zero or one; R4 is --(CH2)t --Y, C1-6 alkyl, or C3-6 cycloalkyl; R1 is --CO2 Z, C1-6 alkyl, CH2 OH, --CONHRy, or CHO; R2 and R3 are independently hydrogen or C1-6 alkyl; Ra and Rb are independently hydrogen or C1-6 alkyl; but when n is one, Ra and Rb together can form a radical of the formula STR2 Y is naphthyl or phenyl, both radicals can be optionally substituted with one to three same or different C1-6 alkyl or halogen; Z is hydrogen or C1-6 alkyl; R5, R6 and Ry are independently hydrogen or C1-6 alkyl; and t is zero to six.
