Quinazoline antifolate thymidylate synthase inhibitors: difluoro-substituted benzene ring analogues.


The synthesis of a series of new C2-methyl-N10-alkylquinazoline-based thymidylate synthase (TS) inhibitors containing difluroinated p-aminobenzoate rings is described. Derivatives of the N10-propargyl and N10-methylquinazoline antifolates were prepared with 2',3'-, 2',5'-, and 2',6'-difluoro substitution. The synthesis of the 2',5'-difluoro analogues… (More)
