Meldrum, B. S. published 《Convulsive effects of 4-deoxypyridoxine in photosensitive baboons》 in 1971. The article was appeared in 《British Journal of Pharmacology》. They have made some progress in their research.Synthetic Route of C8H12ClNO2 The article mentions the following:
In baboons (Papio papio) which when exposed to intermittent light stimulation (ILS) showed myoclonus and electroencephalographic signs of epilepsy, deoxypyridoxine-HCl (I) (10-20 mg/kg, i.v.) did not modify the responses, while 15 min-2 hr after 40-60 mg I/kg, the myoclonic responses to ILS were enhanced. Animals normally giving transient myoclonic responses showed rhythmic myoclonus of the eyelids and face continuing for several sec after the end of ILS. In 4 out of 6 baboons after 80-100 mg I/kg this self-sustaining myoclonus developed into a full tonic-clonic seizure at least once 45-180 min after the drug injection. The injection of 105-150 mg I/kg not only enhanced myoclonic responses to ILS but also led to the appearance after 46-67 min of spontaneous seizures. These recurred every 10-15 min, were often only partial, and commonly originated in, and were sometimes confined to, the occipital cortex. An excess of pyridoxine, given i.v. a few minutes before and after the I, blocked both the enhancement of photosensitivity produced by 100 mg I/kg and spontaneous seizures produced by 150 mg/kg. I may produce these convulsive effects by interfering with the formation or action of pyridoxal phosphate. And 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride (cas: 148-51-6) was used in the research process.
5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride(cas:148-51-6 Synthetic Route of C8H12ClNO2) is a vitamin B6 antimetabolite with diverse biological activities. It inhibits transport of pyridoxine , pyridoxal, and pyridoxamine in and reduces growth of S. carlsbergensis cells. DOP inhibits sphingosine-1-phosphate (S1P) lyase and reduces cyclic stretch-induced apoptosis in alveolar epithelial MLE-12 cells.
