Discovery of 148-51-6

There is still a lot of research devoted to this compound(SMILES：OC1=C(C)C(CO)=CN=C1C.[H]Cl)Category: pyrimidines, and with the development of science, more effects of this compound(148-51-6) can be discovered.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Synthetical and natural phellandrene, published in 1905, which mentions a compound: 148-51-6, mainly applied to , Category: pyrimidines.

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).

Compound: 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride, is researched, Molecular C8H12ClNO2, CAS is 148-51-6, about Inhibition of growth and increased mortality of Mexican bean beetle larvae fed with thiamine and pyridoxine antagonists and reversal of effect with vitamin supplementation. Author is Gothilf, Shmuel; Waites, Robert E..

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.

Larval medium (50 g.) was saturated with 100 ml. of water containing 0.5-0.1 g. of the compound and 100 housefly eggs added. After 4 days it was examined for larvae and 3 days later for pupae. Emerging flies laid their eggs on untreated medium after 7 days. A sample of eggs remained in the medium, which was examined for larvae. The flies of this generation were reared to the adult stage. Compounds (245) are listed which are larvicides at 0.5 g. but not at 0.1 g. dosage; 64 compounds are larvicides at a dosage of ≤0.1 g.; 19 cause mortality in the pupal stage. 1,4-Bis(3-hydroxypropionyl)piperazine dimethanesulfonate causes low oviposition or failure of eggs to hatch at 0.05 and 0.025%, low enough to permit some adult emergence.

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.
