Synthesis of 10-acetyl-5,8-dideazafolic acid: a potent inhibitor of glycinamide ribonucleotide transformylase
摘要:
10-Acetyl-5,8-dideazafolic acid has been synthesized in good yield from the parent compound, 5,8-dideazafolic acid. This quinazoline folate analogue showed no activity as a substrate for the folate-requiring de novo purine biosynthetic enzyme glycinamide ribonucleotide transformylase isolated from the murine lymphoma cell line L5178Y, but proved to be a potent competitive inhibitor, Ki = 1.3 microM, of the purified enzyme.

3-hydroxypropyl, and cyanomethyl substituents at N10 is described. In general, the synthetic route involved monoalkylation of diethyl N-(4-amino-benzoyl)-L-glutamate, coupling of the resulting secondary amine with 2-amino-6-(bromomethyl)-4-hydroxyquinazoline hydrobromide in N,N-dimethylacetamide with calcium carbonate as the base, and deprotection using mild alkali. The cyanomethyl derivatives was found
