Benfotiamine is a synthetic S-acyl derivative of thiamine (vitamin B1) that functions as a lipid-soluble thiamine precursor. It suppresses oxidative stress-induced NF-κB activation and inhibits glucose-induced vascular dysfunction by activating transketolase, thereby blocking major pathways of hyperglycemic damage including the advanced glycation end-product (AGE) and protein kinase C (PKC) pathways. Downstream, benfotiamine reduces endotoxin-induced inflammation and prevents microvascular complications in diabetic models. [1]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
