  Tumor-Targeting with Novel Non-Benzoyl 6-Substituted Straight Chain Pyrrolo[2,3-d]pyrimidine Antifolates via Cellular Uptake by Folate Receptor α and Inhibition of de Novo Purine Nucleotide Biosynthesis

  摘要：

  A new series of 6-substituted straight side chain pyrrolo[2,3-d]pyrimidines 3a-d with varying chain lengths (n = 5-8) was designed and synthesized as part of our program to provide targeted antitumor agents with folate receptor (FR) cellular uptake specificity and glycinamide ribonucleotide formyltransferase (GARFTase) inhibition. Carboxylic acids 4a-d were converted to the acid chlorides and reacted with diazomethane, followed by 48% HBr to generate the alpha-bromomethylketones 5a-d. Condensation of 2,4-diamino-6-hydroxypyrimidine 6 with 5a-d afforded the 6-substituted pyrrolo[2,3-d]pyrimidines 7a-d. Hydrolysis and subsequent coupling with diethyl L-glutamate and saponification afforded target compounds 3a-d. Compounds 3b-d showed selective cellular uptake via FR alpha and -beta, associated with high affinity binding and inhibition of de novo purine nucleotide biosynthesis via GARFTase, resulting in potent inhibition against FR-expressing Chinese hamster cells and human KB tumor cells in culture. Our studies establish, for the first time, that a side chain benzoyl group is not essential for tumor-selective drug uptake by FR alpha.
