Compare Abstract, 1903, i, 845. tert.-Carvomenthyl chloride, obtained from tert.-carvomenthol, boils at 83.5-84.5° under 12 mm. pressure, has a sp. gr. 0.932 at 20°/4°, and forms tert.-carvomenthene, which boils at 174-176°, has a sp. gr. 0.811 at 20°/4°, and nD 1.45709. On treatment with bromine in strongly cooled light petroleum solution, this yields carvomenthene dibromide, which boils between 130° and 144° under 11 mm. pressure, has a sp. gr. 1.208 at 20°/4°, is optically inactive, and by alcoholic potassium hydroxide is converted into a hydrocarbon or mixture of hydrocarbons which must have the constitution (the original abstract includes an equation). This distils in two fractions: the larger boils at 175-180°, has a sp. gr. 0.825 at 20°/4°, and nD 1.46693; the smaller boils at 180-185°, has a sp. gr. 0.828 at 20°/4°, and nD 1.4673. The hydrocarbon is not identical therefore with natural phellandrene. Both fractions are optically inactive and give a red coloration with sulphuric acid in acetic acid solution. A specimen of phellandrene from Phellandrum aquaticum, which boils at 165-168°, has a sp. gr. 0.844 at 20°/4°, nD 1.47575, and [α]D +8°37′ at 20°, reacts with hydrochloric acid in acetic acid solution to form a dextrorotatory chloro-derivative, C10H17Cl, which melts at 110° and boils at 86° under 11 mm. pressure, and a dichloride, C10H18Cl2, which boils at 122.5-125° under 16 mm. pressure, and has a sp. gr. 1.006 at 20°/4° and nD 1.48516 at 20° (compare Pesci, Abstract, 1886, 1038).

Let’s take a look at the latest research on this compound (cas:148-51-6).

Repressed growth and survival of Mexican bean beetle (Epilachna varivestis) larvae were observed when the larvae were fed leaves dipped in 1% solutions of the vitamin analogs oxythiamine, pyrithiamine, or deoxypyridoxine. When the corresponding vitamins, thiamine or pyridoxine, were added to the antivitamins in a 1:1 ratio, the adverse effects of the antivitamins were reversed. Sulfanilamide and pantoyltaurine also increased mortality when used as 1% solutions, but pantothenyl alc., 2-picolinic acid, and 3-acetylpyridine were ineffective.

Compound: 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride(SMILESS: OC1=C(C)C(CO)=CN=C1C.[H]Cl,cas:148-51-6) is researched.Related Products of 481054-89-1. The article 《Pyridoxine-derived bicyclic amido-, ureido-, and carbamato-pyridinols: synthesis and antiangiogenic activities》 in relation to this compound, is published in Organic & Biomolecular Chemistry. Let’s take a look at the latest research on this compound (cas:148-51-6).

We recently developed an efficient and practical synthesis for a novel series of pyridoxine-derived 6-amido-2,4,5-trimethylpyridin-3-ols and found that this novel scaffold has outstanding activity to inhibit angiogenesis measured by the quant. chick embryo chorioallantoic membrane (CAM) assay. As an effort to extend the scope of the amidopyridinol scaffold, we here report the synthesis and antiangiogenic activities of a series of bicyclic versions of the amidopyridinol including five- and six-membered cyclic amide-, cyclic urea-, and cyclic carbamate-fused pyridinols. The six membered bicyclic derivatives were prepared by the reported procedures, and the five-membered ring-fused ones were synthesized by new synthetic methods developed in this study. CAM assays showed that both six- and five-membered lactam-fused pyridinols have activities comparable to sunitinib malate, the pos. control, in inhibition of vascular endothelial growth factor-induced angiogenesis. On the other hand, the urea and the carbamate derivatives showed modest to moderate antiangiogenic activities. In summary, some bicyclic aminopyridinols can provide a good platform for structural exploitation in future medicinal chem. work.
