Abstract
The present invention discloses a breast cancer treatment triptolide liposome preparation and a preparation method thereof, wherein the breast cancer treatment triptolide liposome preparation is a liposome preparation prepared from a breast cancer treatment traditional Chinese medicine active effective component triptolide. The preparation method comprises: adopting an ethanol injection method to prepare liposomes to obtain the breast cancer (breast cancer and triple-negative breast cancer) treatment triptolide liposome preparation. According to the breast cancer treatment triptolide liposome preparation, in vivo animal anti-cancer pharmacological experiment results show that: significant growth inhibition effects are provided for breast cancer and triple-negative breast cancer, and anti-cancer activity of the breast cancer treatment triptolide liposome preparation is respectively and significantly higher than anti-cancer activities of chemotherapy drugs such as paclitaxel and cisplatin. In addition, the triptolide liposome preparation provides a higher anti-cancer effect than the triptolide non-liposome preparation.
Description
One, technical field
The present invention relates to the Chinese medicine technical field, specifically relate to a kind of triptolide Liposomal formulation for the treatment of breast carcinoma and preparation method thereof.
Two, background technology
Cancer is the formidable enemy of harm humans health.The annual new cases of cancer of China approximately has 1,600,000 people, and that dies from cancer every year approximately has 1,300,000 people, rises year by year because of the dead number of cancer in the whole nation, the zone occurred frequently that China is the cancers such as breast carcinoma, pulmonary carcinoma, and cancer mortality is high.
There is no at present the most of cancer patients of effective cured substance.Though chemotherapeutics has certain curative effect to cancer, toxic and side effects is large, and Chinese patent medicine is generally lower to the curative effect of cancer, and curative effect is all undesirable.
The inventor is through the arduous anticancer active substance of studying the Chinese medicines such as Herba Phyllanthi Urinariae, Ramulus et folium taxi cuspidatae, dry maxima skin, Radix Tripterygii Wilfordii decades, therefrom extract multiple anti-cancer active compound, through anticancer experimentation, show, the cancerous cell such as human breast carcinoma, pulmonary carcinoma and zoografting carcinoma are all had to significant inside and outside anticancer therapy effect, and applied for obtaining 10 antineoplastic product invention patent certificates (as the patent No. is respectively: ZL200410041122.1; ZL200610085781.4; ZL200610085781.4; ZL200810124590.3; ZL200810124588.6; ZL201210033666.8 etc.).On the basis of above-mentioned research, the inventor studies again and has invented a kind of triptolide Liposomal formulation for the treatment of breast carcinoma and preparation method thereof, and its active anticancer is high, toxicity is low.
