WebIn this study, we report that human tumor cells respond to de novo purine synthesis blockade by GART inhibitors with p53 stabilization, but that the downstream transcriptional activation events causative of a G 1 arrest are defective. The mechanism of inactivation of the p53 response involves interference with the posttranslational phosphorylation and … WebDec 5, 2003 · GART inhibitors are unique in that they are inactive against the classical enzymatic targets for antifolates, i.e. dihydrofolate reductase and thymidylate synthase, but cause a potent inhibition of purine synthesis and consequent cytotoxicity ( 26) without detectable DNA damage ( 16, 27 ).
