N3PT Chemical Properties, Uses, Production
Uses
N3PT (N3-pyridyl thiamine) is a potent and selective transketolase inhibitor. N3PT is pyrophosphorylated and then binds to transketolase with an Kd value of 22 nM (Apo-TK, transketolase lacking bound thiamine)[1].
in vivo
N3PT (compound 1) (100 mg/kg; i.v.; twice a day; 2 weeks) shows inhibitory effect on transketolase activity without significantly anti-tumor activity in HCT-116 tumor-bearing nude mice[1].
| Animal Model: | HCT-116 tumor-bearing nude mice[1] |
| Dosage: | 100 mg/kg |
| Administration: | Intravenous injection; twice a day; 2 weeks |
| Result: | Decreased the activity of transketolase with no apparent effect on tumor size. Indicated that there were alternative pathways to generate ribose for DNA synthesis that were operating in these tumor cell lines. |
