Synthesis of novel 5-substituted pyrrolo[2,3-d]pyrimidine antifolates as selective and potent anti-tumor agents
… and/or PCFT and over RFC targets inhibition of GARFTase dependent salvage pathway for purine biosynthesis inside the tumor. Based on this premise, five 5-substituted pyrrolo[2,3-<em>d</em>]pyrimidines have been designed, synthesized and characterized. Among them four are novel compounds and one …

Synthesis of furo[2,3-d]pyrimidines, thieno[2,3- d]pyrimidines, pyrrolo[2,3-d]pyrimidines as classical and nonclassical antifolates, receptor tyrosine kinase (RTK) inhibitors and antimitotic agents
… glycinamide ribonucleotide formyltransferase (GARFTase) are important folate dependent enzymes that are targets for cancer chemotherapy and the treatment of infectious diseases. Classical antifolates, in most cases, are substrates for folypoly - γ - glutamate synthase (FPGS) and rely on folate …

The proton-coupled folate transporter: biology and therapeutic applications to cancer
… ribonucleotide (GAR) formyltransferase (GARFTase) in the de novo purine biosynthesis pathway as the principle drug target. This was confirmed by in situ measurement of [14C]glycine incorporation into [14C]formylGAR in treated cells. Furthermore, contraction of intracellular purine …
