ABSTRACT:
The present invention provides methotrexate analogs having the formula: ##STR1## wherein R is methyl or hydro, X is halo or hydro, and D.sub.1 is --NR.sub.1 R.sub.2 wherein either both R.sub.1 and R.sub.2 are hydrogen, or one is hydrogen and the other is C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 haloalkyl, cyano C.sub.1 -C.sub.5 alkyl, C.sub.1 -C.sub.5 hydroxyalkyl, alkoxyalkyl wherein the alkoxy and the alkyl have 1-5 carbon atoms, carboxy C.sub.1 -C.sub.5 alkyl, phenyl, C.sub.1 -C.sub.5 alkyl phenyl, C(.dbd.O)R' wherein R' is hydrogen, C.sub.1 -C.sub.5 alkyl, phenyl, or C.sub.1 -C.sub.5 alkyl phenyl, C(.dbd.O)OR" wherein R" is hydrogen, C.sub.1 -C.sub.5 alkyl, phenyl, or C.sub.1 -C.sub.5 alkyl phenyl, amino, C(.dbd.NH)NH.sub.2, C(.dbd.O)NH.sub.2, or C(.dbd.S)NH.sub.2, and structurally related derivatives, as well as pharmaceutical compositions comprising such MTX analogs, methods of synthesis of the MTX analogs, and use of the MTX analogs in modulating cellular functions, or in treating cancer and other diseases or disorders capable of being treated using MTX.
