OXYTHIAMINE HYDROCHLORIDE Chemical Properties,Usage,Production

Uses

thiamine antagonist

Uses

Oxythiamine chloride hydrochloride is suitable for use:

• as a reference standard for calibration curve generation in liquid chromatography-tandem mass spectrometry (LC-MS/MS) for oxythiamine pyrophosphate (OTPP) quantification in red blood cells
• as a thiamine transport inhibitor in human mammary epithelial cells (HMEC) and breast cancer cell lines
• in the synthesis of oxythiamineH picrolonate salt

Definition

ChEBI: A hydrochloride obtained by combining oxythiamine chloride with one molar equivalent of hydrochloric acid.

General Description

Oxythiamine is a thiamine antimetabolite and the source through diet is by consuming acidic thiamine rich foods.

Biochem/physiol Actions

Oxythiamine (OT) is a thiamine antagonist. It is a transketolase inhibitor and is employed to study anti-metastatic mechanisms, especially those involving metalloproteinases (MMP). It significantly sensitizes human hepatocellular carcinoma cells (HCC) to sorafenib, favoring tumor suppression.
