General description

S-Benzoylthiamine O-monophosphate (Benfotiamine) is an amphiphilic S-acyl thiamine derivative. It is a lipid-soluble vitamin. Benfotiamine contains a thiazole ring. Benfotiamine has a greater bioavailability than thiamine.

Application

S-Benzoylthiamine O-monophosphate has been used to determine its effect on ischemia and reperfusion in skeletal muscles of rat.

Biochem/physiol Actions

S-Benzoylthiamine O-monophosphate (Benfotiamine) is a therapeutic agent. It helps in the prevention of diabetic complications such as, retinopathy, neuropathy and nephropathy. Benfotiamine inhibits the synthesis of glycation end products (AGEs) in diabetes. Benfotiamine is considered as a nutraceutical product for the prevention of diabetic neuropathy.

Thiamine, known as vitamin B(1), plays an essential role in energy metabolism. Benfotiamine (S-benzoylthiamine O-monophoshate) is a synthetic S-acyl derivative of thiamine. Once absorbed, benfotiamine is dephosphorylated by ecto-alkaline phosphatase to lipid-soluble S-benzoylthiamine. Transketolase is an enzyme that directs the

Pericytes regulate vascular tone, perfusion pressure and endothelial cell (EC) proliferation in capillaries. Thiamine and benfotiamine counteract high glucose-induced damage in vascular cells. We standardized two human retinal pericyte (HRP)/EC co-culture models to mimic the diabetic retinal microvascular environment. We

Benfotiamine (BFT) is a transketolase activator that directs glucose to the pentose phosphate pathway. The present study investigated whether BFT improves the recovery after myocardial infarction (MI) and explored underlying mechanisms of protection.

This study was designed to investigate the molecular mechanisms by which benfotiamine, a lipid-soluble analogue of vitamin B1, affects lipopolysaccharide (LPS)-induced inflammatory signals leading to cytotoxicity in the mouse macrophage cell line RAW264.7. Benfotiamine prevented LPS-induced apoptosis, expression of the
