Abstract
Description
technical field
[0001] The invention relates to the technical field of medicine, in particular to a novel preparation method of docetaxel injection. Background technique
[0002] Docetaxel (docetaxel, trade name Taxotere) is a semi-synthetic paclitaxel derivative with molecular formula C 13 h 53 NO.3H 2 o, molecular weight 861.9. The product was first launched in Mexico in April 1995, and is now available in Britain, the United States, France, Italy, Germany, Japan and other countries. Docetaxel can accelerate the polymerization of tubulin into microtubules and delay the depolymerization of microtubules, resulting in the formation of stable non-functional microtubule bundles, thereby disrupting mitosis and cell proliferation. Its cytotoxic effect is 1.3-12 times that of paclitaxel; the intracellular drug concentration is 3 times that of paclitaxel; the intracellular retention time is 3 times that of paclitaxel.
