Compounds of the formula ##STR1## and the pharmaceutically acceptable salts thereof wherein R is: --CO--CH.sub.3, --CHOH--CH.sub.3, --CO--CH.sub.2 OH, --CHOH--CH.sub.2 OH, hydrogen, hydroxy, 1 to 3 carbon alkyl, 1 to 3 carbon terminal hydroxyalkyl; or, a 2 to 7 carbon ester or diester of said --CO--CH.sub.2 OH, --CHOH--CH.sub.2 OH, --CHOH--CH.sub.3 or of said 1 to 3 carbon terminal hydroxyalkyl; or said --CO--CH.sub.2 OH, --CHOH--CH.sub.2 OH, or --CHOH--CH.sub.3 or said 1 to 3 C-terminal hydroxyalkyl having 1 to 6 carbon alkyl or aryl ether replacements of one or more of the hydroxyls; or the 13-ketimine derivatives of --CO--CH.sub.3 and --CO--CH.sub.2 OH; Y is hydrogen, hydroxy, or methoxy, X is O or NH, but when Y is hydrogen or hydroxy, X must be O; at least one of R.sup.1 and R.sup.2 is hydrogen and the other is hydrogen, hydroxy, or methoxyl; B is H, alkyl or optionally substituted aryl lower alkyl, said alkyl or optionally substituted aryl lower alkyl also optionally containing hydroxy, alkoxy, carbonyl, cyano or ester group substitutions; or B and R.sup.2 taken together, in order, are the methylene-oxygen bridge --CH.sub.2 --O--; and A is --CHR.sup.3 CN wherein R.sup.3 is H, optionally substituted aryl, alkyl or optionally substituted aryl lower alkyl, said alkyl or optionally substituted aryl lower alkyl optionally containing hydroxy, alkoxy, carbonyl, or ester group substitutions are disclosed. These compounds are useful anti-tumor agents.
