3-Substituted isocoumarins 1-19 were synthesized and evaluated for their thymidine phosphorylase inhibitory activity. Eight (8) compounds exhibited a varying degree of inhibitory activity towards thymidine phosphorylase from E. coli with IC50 values between 61- 402 iM. The activities were compared with the standard 7-deazaxanthine (IC50 = 39.28 ± 0.76 iM).
