Asymmetric Synthesis of Inhibitors of Glycinamide Ribonucleotide Transformylase
摘要:
Glycinamide ribonucleotide transformylase (GAR Tfase) catalyzes the first of two formyl transfer steps in the de novo purine biosynthetic pathway that require folate cofactors and has emerged as a productive target for antineoplastic therapeutic intervention. The asymmetric synthesis and evaluation of the two diastereomers of 10-methylthio-DDACTHF (10R-3 and 10S-3) and related analogues as potential inhibitors of GAR Tfase are reported. This work, which defines the importance of the C10 stereochemistry for this class of inhibitors of GAR Tfase, revealed that both diastereomers are potent inhibitors of rhGAR Tfase (10R-3 K-i = 210 nM, 10S-3 K-i = 180 nM) that exhibit effective cell growth inhibition (CCRF-CEM IC50 80 and 50 nM, respectively), which is dependent on intracellular polyglutamation by folylpolyglutamate synthetase (FPGS) but not intracellular transport by the reduced folate carrier.
