Abstract
The invention belongs to the technical field of pharmaceutical preparations, and concretely relates to temsirolimus for injection and a preparation method thereof. The preparation method comprises dissolving a prescribed amount of temsirolimus and an anti-oxidant in anhydrous alcohol, mixing uniformly, adding a dispersant, re-mixing uniformly, freeze drying and removing the ethanol to obtain the temsirolimus. The preparation provided by the invention is few in prescription component; and the preparation method is convenient and easy, improves disadvantages of complex technology in present prescription, and greatly minimizes components such as alcohols and the like that may cause injection pain, thereby being relatively safe and reliable.
Description
technical field [0001] The invention belongs to the technical field of pharmaceutical preparations, and in particular relates to a temsirolimus for injection and a preparation method thereof. Background technique [0002] Temsirolimus is the 42-bis-hydroxymethyl propionate of rapamycin, which exhibits cell growth and proliferation inhibition in vivo, and can delay the time of tumor cell development or tumor recurrence. Temsirolimus binds to the cellular protein FKBP and forms a complex that inhibits the enzyme mTOR (mammalian target of rapamycin). Inhibition of mTOR's kinase activity inhibits various signal transduction pathways, including cellular The cell proliferation activated by kinetochore regulates the transcription of mRNAs of some key proteins in the G1 phase of the cell cycle and the transcription induced by IL-2, thereby inhibiting the progression of the cell cycle from G1 to S, thereby producing an anticancer effect. [0003] Temsirolimus has been shown to inhib...
