Design, synthesis, and biological evaluation of 10-methanesulfonyl-DDACTHF, 10-methanesulfonyl-5-DACTHF, and 10-methylthio-DDACTHF as potent inhibitors of GAR Tfase and the de novo purine biosynthetic pathway.

Abstract：

:The synthesis and evaluation of 10-methanesulfonyl-DDACTHF (1), 10-methanesulfonyl-5-DACTHF (2), and 10-methylthio-DDACTHF (3) as potential inhibitors of glycinamide ribonucleotide transformylase (GAR Tfase) and aminoimidazole carboxamide ribonucleotide transformylase (AICAR Tfase) are reported. The compounds 10-methanesulfonyl-DDACTHF (1, K(i) = 0.23 microM), 10-methanesulfonyl-5-DACTHF (2, K(i) = 0.58 microM), and 10-methylthio-DDACTHF (3, K(i) = 0.25 microM) were found to be selective and potent inhibitors of recombinant human GAR Tfase. Of these, 3 exhibited exceptionally potent, purine sensitive growth inhibition activity (3, IC50 = 100 nM) against the CCRF-CEM cell line being 3-fold more potent than Lometrexol and 30-fold more potent than the parent, unsubstituted DDACTHF, whereas 1 and 2 exhibited more modest growth inhibition activity (1, IC50 = 1.0 microM and 2, IC50 = 2.0 microM).
