3-Mercaptopicolinic Acid, Hydrochloride (3-MPA HCl) is a potent gluconeogenesis inhibitor. In perfused rat livers, gluconeogenesis was inhibited when lactate, pyruvate, or alanine served as substrate, but not with fructose, suggesting phosphoenolpyruvate carboxykinase as the site of inhibition. 3-Mercaptopicolinic Acid, Hydrochloride has been used in studies of DNA and RNA, enzyme kinetics, protein structure, and enzyme inhibition.

Can you please assist with solubility troubles? can't solve it in water, DMSO or ethanol.

Asked by: Jz28sail
Thank you for your question. sc-206655, 3-Mercaptopicolinic Acid, Hydrochloride is soluble in water. Once in water, it dissolves well by rapid stirring, sonication or gentle warming (in a 45-60°C water bath) producing a yellowish solution. sc-206655 is not very soluble in DMSO, ethanol or methanol. It has been reported that 3-Mercaptopicolinic Acid, Hydrochloride is soluble to 0.2 mg/ml in PBS, pH 7.2.

Rated 5 out of 5 by from BalanBalan, MD. et al. (PubMed 26322521) performed a structural study on 3-Mercaptopicolinic Acid, a potent hypoglycemic agent, that acts through inhibition of glucose synthesis via the specific inhibition of phosphoenolpyruvate carboxykinase (PEPCK) in the gluconeogenesis pathway. The structural study suggests that binding of MPA to the allosteric pocket stabilizes an altered conformation of the nucleotide-binding site that in turn reduces the affinity of the enzyme for the nucleotide. -SCBT Publication Review
