Side chain modified 5-deazatolate and 5-deazatetrahydrotolate analogs as mammalian folylpolyglutamate synthetase and glycinamide ribonucleotide formyltransferase inhibitors: synthesis and in vitro biological evaluation. 47. N-[4-[[(3,4-Dihydro-4-oxo-1,2,3-benzotriazin-6-yl)methyl]amino]benzoyl-L-glutamic acid, a novel a-ring analog of 2-desamino-5,8-dideazafolic acid

variable substrate (Ki = 2.3 microM). It was a substrate for murine folylpolyglutamate synthetase with kinetic characteristics (Km = 28 microM) comparable to those of aminopterin, and it inhibited the growth of L1210 cells in culture (IC50 = 0.52 microM). The structural modification of the A-ring embodied in ADDF appears to offer a novel, heretofore unexplored approach to the design of TS inhibitors.
