Bufalin liposome, preparation method therefor and application thereof

The present invention provides a bufalin liposome comprising a liposome bilayer and bufalin. The liposome bilayer comprises phospholipid, sterol and polyethylene glycol (PEG)-derived compound. The liposome of the present invention can be used to treat cancer, especially a cancer chosen from liver cancer, lung cancer, ovarian cancer, prostate cancer, colon cancer, pancreas cancer, gastric cancer, and leukemia. The preparation method of the present invention is simple, and the bufalin liposome can increase an effect of antitumor, reduce a toxicity compared with bufalin monomer, and has wide applications.

Triptolide derivatives and preparation method and use thereof

Tripyolide-nucleic acid aptamer derivatives, a preparation method and use thereof are shown. The structure of the triptolide-nucleic acid aptamer derivatives is as shown by formula I, wherein the definitions of R.sub.1-R.sub.7, G, A, B, M, Z and X are described. The present invention uses a nucleic acid aptamer and triptolide or modified compounds thereof as the starting materials, and introduces a linking group A at the C-14 hydroxyl group, epoxy groups and five-membered ring lactones in triptolide, then connects it to a nucleic acid aptamer B, and obtains the triptolide-nucleic acid aptamer derivatives. The triptolide-nucleic acid aptamer derivatives of the present invention have the characteristics of good targeting, a high anti-cancer activity, low toxicity and side effects, good water solubility and high bioavailability, and the preparation method of the present invention is scientific and reasonable and has a controllable quality and good repeatability, and is thereby suitable for production.
