Yamashita, Junko;Hirata, Yukio published 《Running fits and γ-aminobutyric acid of the superior colliculus of the mouse》 in 1979. The article was appeared in 《Journal of Nutritional Science and Vitaminology》. They have made some progress in their research.Electric Literature of C8H12ClNO2 The article mentions the following:

The γ-aminobutyric acid content of the superior colliculus of the mouse brain was decreased following the induction of running fits by the intracollicular injection of the antivitamin B₆ compound semicarbazide. Aminooxyacetic acid hemihydrochloride, an inhibitor of 4-aminobutyrate-2-oxoglutarate aminotransferase (EC 2.6.1.19) with a resultant increase in GABA levels, has been shown to exert an antidotal effect on the induction of running fits. Therefore, this type of convulsive behavior is apparently associated with diminished levels of GABA in the superior colliculus. Running fits were also induced by the antivitamin B₆ compounds thiosemicarbazide and 4-deoxypyridoxine-HCl, and presumedly this was also the result of a decrease in GABA level. 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 Electric Literature of C8H12ClNO2) is a strong antagonist of vitamin B6. Deoxypyridoxine hydrochloride has been used as an analytical reference standard for the quantification of the analyte in food samples using high performance liquid chromatography.

The research results were published in《Chemistry – A European Journal》 in 2010.HPLC of Formula: 148-51-6 The article conveys some information:

3-Pyridinols bearing amine substitution para to the hydroxylic moiety have previously been shown to inhibit lipid peroxidation more effectively than typical phenolic antioxidants, for example, α-tocopherol. We report here high-yielding, large-scale syntheses of mono- and bicyclic aminopyridinols from pyridoxine hydrochloride (i.e., vitamin B₆). This approach provides straightforward, scaleable access to novel, potent, mol. scaffolds whose antioxidant properties have been investigated in homogeneous solutions and in liposomal vesicles. These mol. aggregates mimic cell membranes that are the targets of oxidative damage in vivo. To complete the study, the researchers used 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride (cas: 148-51-6) .

Formula: C8H12ClNO2《Synthesis of aflatoxins by the non-growing mycelia of Aspergillus parasiticus and the effect of inhibitors》 was published in 1975. The authors were Gupta, S. R.;Prasanna, H. R.;Viswanathan, L.;Venkitasubramanian, T. A., and the article was included in《Journal of General Microbiology》. The author mentioned the following in the article:

Aflatoxins were synthesized by nongrowing mycelia of A. parasiticus, the amount and type (B or G) being dependent on the buffer used in the suspension medium. Incorporation of acetate-14C into aflatoxin was decreased by compounds that inhibit ATP production or interfere with the utilization of certain amino acids. In contrast, the specific activities of aflatoxins were increased by compounds that diverted acetate from metabolic pathways other than those leading to aflatoxin formation. 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 Formula: 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.

cf. preceding abstract Derivatives of I were prepared by treatment of 2,2,8-trimethyl-4H-m-dioxino[4,5-c]pyridine-5-methanol benzoate with HCl. I (R = OH) refluxed with SOCl₂ and the residue treated with EtOH produced I (R = Cl). The catalytic (C) hydrogenation of I (R = Cl) afforded I (R = H). I (R = H) refluxed in KOH gave 4-deoxypyridoxine (II). I (R = Cl) stirred with Na₂S₂O₅ produced I (R = SO₃H). KCNS refluxed with I (R = Cl) gave I (R = SCN). Similarly, I (R = Cl) stirred with NaHS gave I (R = SH). I (R = H) was as active and I (R = SO₃H) one-half as active as II in depressing lymphocyte count in rats fed a pyridoxine deficient diet, while the other reported derivatives were inactive. None of the other compounds inhibited the growth of Saccharomyces carlsbergensis. Cf. Schmidt, and Giesselmann, CA 58, 1429d.

The following compounds increased the mortality rate when given with an x-ray dose of 505 r. (L.D._16/30): 4-deoxypyridoxine-HCl, isonicotinic acid hydrazide,DL-tryptophan, DL-kynurenine, and L-kynurenine. Taurine, given with 590 r. (L.D._64/30), increased the survival rate.

Category: alcohols-buliding-blocks《Inhibition of colitis by ring-modified analogues of 6-acetamido-2,4,5-trimethylpyridin-3-ol》 was published in 2020. The authors were Chaudhary, Chhabi Lal;Chaudhary, Prakash;Dahal, Sadan;Bae, Dawon;Nam, Tae-gyu;Kim, Jung-Ae;Jeong, Byeong-Seon, and the article was included in《Bioorganic Chemistry》. The author mentioned the following in the article:

6-Aminopyridin-3-ol scaffold has shown an excellent anti-inflammatory bowel disease activity. Various analogs with the scaffold were synthesized in pursuit of the diversity of side chains tethering on the C(6)-position. SAR among the analogs was investigated to understand the effects of the side chains and their linkers on their anti-inflammatory activities. In this study, structural modification moved beyond side chains on the C(6)-position and reached to pyridine ring itself. It expedited to synthesize diverse ring-modified analogs of a representative pyridine-3-ol, 6-acetamido-2,4,5-trimethylpyridin-3-ol. In the evaluation of compounds on their inhibitory actions against TNF-α-induced adhesion of monocytic cells to colonic epithelial cells, an in vitro model mimicking colon inflammation, the effects of compounds I , II, and III were greater than tofacitinib, an orally available anti-colitis drug, and compound dehydroxylated analog II exhibit the greatest activity. In addition, TNF-α-induced angiogenesis, which permits more inflammatory cell migration into inflamed tissues, was significantly blocked by compounds I and II in a concentration-dependent manner. In the comparison of in vivo therapeutic effects of compounds I , II, and III on dextran sulfate sodium (DSS)-induced colitis in mice, compound dehydroxylated analog II was the most potent and efficacious, and compound demethylated analog III was better than compound I which exhibited a similar degree of inhibitory effect to tofacitinib. 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 Category: alcohols-buliding-blocks) is a strong antagonist of vitamin B6.
