摘要:
The present invention discloses a ziyuglycoside II polymer micelle, and it is prepared by following raw/auxiliary materials at predetermined weight ratio: 20 parts of ziyuglycoside II and 100-5000 parts of mPEG-PLA-Phe(Boc). Quality evaluation test indicates that only using mPEG-PLA-Phe(Boc) according to the present invention as carrier materials, the quality of ziyuglycoside II polymer micelle prepared is the best, but using other additional materials can lead to the lowered preparation quality. In the pharmacodynamic experiment, compared with the model group, the ziyuglycoside II micelle of the present invention can significantly increase the amounts of WBC, RBC, PLT, NEUT, and HGB in peripheral blood, and the efficacy is obviously better than the original drug ziyuglycoside II, indicating the ziyuglycoside II polymer micelle of the present invention has a better treatment and/or prevention effects on bone marrow suppression, and can improve the bioavailability of insoluble drug ziyuglycoside II.
