Oxythiamine Chemical Properties, Uses, Production
Chemical Properties
White solid
Uses
Oxythiamine (Hydroxythiamin), an analogue of anti-metabolite, can suppress the non-oxidative synthesis of ribose and induce cell apoptosis. Oxythiamine is a thiamine antagonist and inhibits transketolase (TK). Oxythiamine inhibits cancer cell apoptosis and inhibits cell proliferation[1][2][3].
Definition
ChEBI: A 1,3-thiazolium cation that is 5-(2-hydroxyethyl)-4-methyl-1,3-thiazole alkylated at the N3 position by a (2-methyl-4-oxo-1,4-dihydropyrimidin-5-yl)methyl group.
Safety Profile
Moderately toxic by subcutaneous route. Experimental reproductive effects. Whenheated to decomposition it emits toxic fumes of NOx and SOx.
in vivo
Oxythiamine (100-500 mg/kg, i.p. 4 days) inhibits tumor growth in Ehrlich's ascites tumor hosting mice[2].
Oxythiamine (250 or 500 mg/kg, daily for 5 week) inhibits tumor cell metastasis via inhibition of MMPs in mice implanted (s.c.) with LLC cells[4].
| Animal Model: | Ehrlich's ascites tumor hosting mice[2] |
| Dosage: | 100-500 mg/kg |
| Administration: | i.p., 4 days |
| Result: | Inhibited tumor growth by 43% at 300 mg/kg and 84% at 500 mg/kg. |
