Certain alpha-methylene-gamma-(4-substituted phenyl)-gamma-butyrolactone bearing thymine, uracil, and 5-bromouracil were synthesized and evaluated for their anticancer activity. These compounds demonstrated a strong growth inhibitory activity against leukemia cell lines. The anticancer potency for the substituents of the lactone C(gamma)-phenyl is in an order of 4-Ph > 4-Cl, 4-Br > 4-Me, 4-NO2 > 4-F. For the pyrimidine portion, 5-bromouracil is more potent than uracil and thymine.
