Pyritinol: A Semi-Synthetic Analog of Vitamin B6

Pyritinol also called pyridoxine disulfide or pyrithioxine is a water soluble analog of vitamin B6 (pyridoxine HCl) [P0561]. Structurally, two Vitamin B6 molecules attached to each other as a disulfide. Pyritinol is a kind of stimulant for the central nervous system (CNS), and is commonly used as a nootropic agent. The effects of pyritinol on nerve receptors have been studied in different neuronal systems associated with age-related decline in brain function, such as Alzheimer’s disease.
