Abstract

The invention relates to an HM-3 polypeptide freeze-dried powder preparation and a preparation method thereof, relating to HM-3 polypeptides. The preparation method comprises the steps of: quantitatively preparing a solution from HM-3 polypeptide and minor ingredients, removing carbon through filter paper and filtering aseptically, then charging a clean and aseptic ampoule according to the specification of 0.5-5ml of per preparation, sending to a freeze dryer for freeze-drying for 20-30 h and then taking out; and covering and carrying out quality detection, obtaining the HM-3 polypeptide freeze-dried powder preparation after the quality is qualified. The HM-3 polypeptide freeze-dried powder preparation prepared by using the method has high activity and purity and better medical effect, and is convenient for carrying and storing.

Description

Technical field: [0001] The invention relates to a HM-3 polypeptide freeze-dried powder preparation and a preparation method thereof, in particular to HM-3 polypeptides. Background technique: [0002] Due to their non-selective cytotoxicity, traditional tumor treatment chemotherapy drugs have relatively large toxic and side effects on patients and are prone to drug resistance. The current method of inhibiting tumor angiogenesis to inhibit tumor nutrition and metastasis has become a new tumor treatment approach, and its greatest potential lies in overcoming drug resistance and low toxicity and side effects. HM-3 is an integrin blocker, which is a polypeptide with integrin and heparin affinity and binding ability, which can effectively inhibit the migration of endothelial cells and tumor neovascularization, and is beneficial to therapeutic entities. Tumors including gastric cancer, liver cancer and lung cancer have good results. The molecular weight of HM-3 polypeptide is 15...
