Novel compounds of formula (I)
wherein
n is 0 to 2;
A is sulfur, CH2, oxygen, -NH- or selenium, provided that when n is 0, A cannot be CH2, and when n is 1, A cannot be CH2 or NH;
X is at least one substituted or unsubstituted C1-C3 alkyl or alkenyl group,
a C2-C3 alkynyl group, a substituted or unsubstituted amino group, sulfur or oxygen;
Ar is a substituted or unsubstituted monocyclic carbocyclic or heterocyclic ring or fused or nonfuxed carbocyclic or heterocyclic ring system; and
R1 and R2 are independently hydrogen or a moiety which forms a readily hydrolyzable ester group or
a pharmaceutically acceptable salt thereof
are found to inhibit the enzyme glycinamide ribonucleotide formyl transferase (GARFT).
A novel method of preparing such compounds is also disclosed, as well as methods and compositions for employing the compounds as antiproliferative agents.
