Molecular Formula | C21H22N4O6S |
Molar Mass | 458.49 |
Density | 1.49±0.1 g/cm3(Predicted) |
Melting Point | 176-1800C |
Solubility | DMSO : ≥ 20 mg/mL mother liquor preservation: sub-package and freeze storage to avoid repeated freezing and thawing;-20 ℃,1 month;-80 ℃,6 months (after dilution, the solution temperature is low and storage may precipitate, as far as possible to use the current preparation) Cell experiment: dissolve with DMSO first: dilute with culture medium then, and the dilution process is recommended to be carried out in stages to avoid too fast concentration change leading to compound precipitation. If the compound is precipitated during the dilution process, it can be redissolved by ultrasound. During dilution, ensure that the final concentration of DMSO in the working fluid should be below 0.1% as far as possible, and the maximum should not exceed 0.5%, and set up a DMSO control group with corresponding concentration. Animal experiment: Dissolve with DMSO first: dilute with water or normal saline, etc. The dilution process is recommended to be carried out in sections to avoid excessive concentra |

2,6-= methyl -4(3H)-quinazolinone was alkylated with tert-pentalyloxymethyl chloride and then bromonated with N-bromosuccinimide, 6-(bromomethyl) -2-methyl -3-[(tert-valeryloxy) methyl]-4(3H)-quinazolinone is obtained. The material and N-[5-methylaminothiophene-2-carbonyl]-L-glutamic acid Diethyl ester condensation, product and sodium hydroxide in ethanol solution at room temperature stirring hydrolysis, and simultaneous deprotection, then acidification results in raltitrexed.
