Description

Oxythiamine, an antimetabolite and a vitamin B1 antagonist, is a well-known thiamine antagonist and inhibitor of transketolase.

IC50 & Target

Vitamin B1, Thiamine, Transketolase[1].

In Vitro

Oxythiamine, an antimetabolite and a vitamin B1 antagonist, is a well-known thiamine antagonist and inhibitor of transketolase. Oxythiamine alters protein expression in a dose dependent manner. The level of alpha-enolase is increased by Oxythiamine treatment, while expression of 14-3-3 protein beta/alpha is suppressed by Oxythiamine at a stratified dose. Oxythiamine causes dynamic changes of total protein expression in time dependent fashion. Oxythiamine suppresses expression of cellular phosphor proteins significantly[2].

Cell Assay
[2]

Human pancreatic carcinoma cell line MIA PaCa-2 is used throughout the study. Experiments are set up in two groups: dose and time-dependent groups. For the dose-dependent group, the cells are stimulated with 5, 50 and 500 μM Oxythiamine (OT) for 48 hours, respectively. The unstimulated cells are considered as control. For the time-dependent group, the cells are stimulated with 50 μM Oxythiamine in MEM containing natural amino acids or 50% of 15 N algal amino acid mixture for 12 and 48 h. The unstimulated cells are considered as the zero time point. Each treatment is repeated four times with 10 mL/flask. The cell pellets are then collected for further analysis[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
