Oxythiamine

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].
