  • A synthetic guanosine analogue antimetabolite. Phosphorylated by hypoxanthine-guanine phosphoribosyltransferase, thioguanine incorporates into DNA and RNA, resulting in inhibition of DNA and RNA syntheses and cell death. This agent also inhibits glutamine-5-phosphoribosylpyrophosphate amidotransferase, thereby inhibiting purine synthesis. (NCI04)
