Synthesis of N-{4-[2-(2-Amino-5,6-dihydro-4(3H)-oxo-7H-pyrrolo[2,3-d]pyrimidin-6-yl)- ethyl]benzoyl}-l-glutamic Acid: A Ring-Contracted Analogue of 5,10-Dideaza-5,6,7,8-tetrahydrofolic Acid
摘要:
This paper describes the synthesis of N-(4-[2-(2-amino-5,6-dihydro-4(3H)-oxo-7H-pyrrolo[2,3-d]-pyrimidin-6-yl)ethyl]benzoyl) -L-glutamic acid (4), which can be viewed as a ring-contracted analogue of 5,10-dideaza-5,6,7,8-tetrahydrofolic acid (DDATHF, 1) in which the C-7 methylene group of the latter has been excised and C-6 joined to N-8. This compound exhibits significant activity as an inhibitor of the growth of human (CCRF-CEM) lymphoblastic leukemic cells in vitro and apparently acts by blocking de novo purine biosynthesis through inhibition of glycinamide ribonucleotide formyltransferase (GAR FTase).
