A series of fourteen 5,8-dideaza analogues of folic and pteroic acids was evaluated for inhibition of 5-aminoimidazole-4-carboxamide ribonucleotide transformylase (AICAR TFase) from chicken liver. Of the 5,8-dideaza folate derivatives studies, 10-oxa-5,8-dideazafolic acid was the most potent inhibitor. The addition of one L-glutamate moiety to the gamma-carboxyl group caused a 6- to 7-fold reduction in Ki in three instances. Two compounds devoid of an L-glutamate were 4- to 6-fold less inhibitory than their parent counterparts possessing one L-glutamate residue.
