The present invention is directed to antifolate compounds having the
structure
wherein: X is CHR.sub.9 or NR.sub.9; Y.sub.1, Y.sub.2, and Y.sub.3
independently are O or S; V.sub.1 and V.sub.2 independently are O, S, or
NZ; Z is H, optionally substituted alkyl, optionally substituted alkenyl,
optionally substituted alkynyl, or alkaryl; R.sub.1 and R.sub.2
independently are H, optionally substituted alkyl, optionally substituted
alkenyl, optionally substituted alkynyl, or alkaryl; R.sub.3 is H,
optionally substituted alkyl, optionally substituted alkenyl, optionally
substituted alkynyl, optionally substituted alkoxy, hydroxyl, or halo;
and R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8, and R.sub.9
independently are H, optionally substituted alkyl, optionally substituted
alkenyl, optionally substituted alkynyl, acyl, --C(O)-alkyl,
--C(O)-alkenyl, or --C(O)--alkynyl; as well as pharmaceutically
acceptable esters, amides, salts, solvates, and prodrugs thereof. The
compounds are useful in pharmaceutical compositions and in methods of
treating multiple conditions, including abnormal cell proliferation,
inflammatory diseases, asthma, and arthritis.
