The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. 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.Recommanded Product: 18436-73-2. The article 《Merits of ascites tumors for chemotherapeutic screening. I》 in relation to this compound, is published in Annals of the New York Academy of Sciences. Let’s take a look at the latest research on this compound (cas:148-51-6).
Ehrlich ascites, Krebs 2 ascites carcinomas, and sarcoma 180 ascites tumor were used in the present study. Fresh ascites fluid containing 106 cancer cells were injected into mice and the recipient regularly developed large amounts of milky ascites (5 to 20 cc.) in 1 to 2 wk and died in 1 to 3 wk. The tumors had 100% takes and there were generally no spontaneous regressions. The exudates contained 5 to 10% normal cells. For the chemotherapy test, a donor mouse was selected 1 to 2 wk, after inoculation and 2 to 5 mL. of milky fluid withdrawn, the cells counted in a hemocytometer, and a proper dilution made with 0.9% NaCl solution I.p. injections of 0.1 mL. of fluid containing 106 cells was made. Each group of animals was divided into a control and treatment group. The progress of the tumors was recorded by daily weight measurement and by measuring the amount of ascitic fluid 10 days after the inoculation. The inhibition effect was then estimated from the effects on the ascites and the survival. Chemotherapeutic agents were injected in solvents as necessary; 0.5 cc. CM-cellulose, 0.5 cc. peanut oil, 0.1 cc. sesame oil were used. One hundred compounds were tested on all 3 tumors; these consisted of nitrogen mustards, ethyleneimines, phosphoramides, folic acid analogs and other pteridines, carbamates, purines, pyrimidines, formamides, steroids, hormones, enzymes, antibiotics, antivitamins, inorganic salts, and others. In 64% of the tests the response to agents was identical in all 3 tumors. A similar study was made of 54 agents on the solid and ascites form of the Ehrlich carcinoma and sarcoma 180. The ascites form usually showed the greater sensitivity to the carcinostatic agent.
As far as I know, this compound(148-51-6)Safety of 5-(hydroxymethyl)-2,4-dimethylpyridin-3-ol hydrochloride can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
