SDS of cas: 148-51-6In 1940, Harris, Stanton A. published 《Vitamin B6. II. Reactions and derivatives》. 《Journal of the American Chemical Society》published the findings. The article contains the following contents:
Vitamin B6-HCl (I) in an equal mixture of C5H5N and Ac2O, allowed to stand overnight and then heated on a steam bath for 20 min., gives vitamin B6 triacetate-HCl [2-methyl-3-acetoxy-4,5-bis(acetoxymethyl)-pyridine-HCl], m. 157°; it is stable in 0.01 N HCl but is slowly hydrolyzed in 0.01 N alkali at 37°. Vitamin B6 dibromide-HBr (II) and 3 equivalents AcOAg in a 22% solution of AcOK in AcOH, heated on the steam bath for 0.5 hrs., give 25% of vitamin B6 diacetate-HCl [2-methyl-3-hydroxy-4,5-bis(acetoxymethyl) pyridine-HCl], m. 160-1°; the aqueous solution gives a good FeCl3 test; it has the same relative stability as the tri-Ac derivative Reduction of II with a PdBaSO4 catalyst in EtOH gives 40% of 2,4,5-trimethyl-3-hydroxypyridine, m. 178°; HCl salt, m. 216°. Catalytic reduction of I with the Adams catalyst gives 2,4-dimethyl-3-hydroxy-5-hydroxymethylpyridine-HCl, m. 267-8°; this is weakly active for the growth and promotion of acid formation by Streptobacterium plantarum, whereas III is inactive. I, exactly neutralized with 1 equivalent of MeONa in MeOH and heated at 125° for 4 hrs., gives a small yield of 2-methyl-3-hydroxy-4-methoxymethyl-5-hydroxymethylpyridine-HCl (III), m. 181°. To complete the study, the researchers used 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride (cas: 148-51-6) .
5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride(cas:148-51-6 SDS of cas: 148-51-6) 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.
