Notes: 6-Thioguanosine-5'-O-diphosphate is an inactive metabolite of the purine analog 6-thioguanine (Item No. 15774) and the immunosuppressive purine analog azathioprine (Item No. 13987).{51291,51292} It is formed from 6-thioguanine via a 6-thioguanosine monophosphate intermediate by phosphorylation and from azathioprine via 6-mercaptopurine (Item No. 23675) and other intermediates by a non-enzymatic process and several enzymatic reactions. Elevated blood levels of 6-thioguanosine-5'-O-diphosphate in patients with Crohn's disease correlate with a lower response rate to azathioprine.{51292}
