Embodiment 1

[0012] Embodiment 1: the preparation of the compound Polyflavanostilbene A tablet involved in the present invention:

[0013] Take 20 grams of compound Polyflavanostilbene A, add 180 grams of conventional excipients for tablet preparation, mix well, and make 1000 tablets with a conventional tablet press.

Embodiment 2

[0014] Embodiment 2: the preparation of the compound Polyflavanostilbene A capsules involved in the present invention:

[0015] Get 20 grams of compound Polyflavanostilbene A, add conventional auxiliary materials such as starch 180 grams for the preparation of capsules, mix well, and pack into capsules to make 1000 capsules.

[0016] The following pharmacodynamic experiments will further illustrate its drug activity.

experiment example

[0017] Experimental example: Polyflavanostilbene A inhibits the proliferation of lung cancer cells cultured in vitro and its effect on normal human cells

[0018] Lung cancer cells in logarithmic growth phase (non-small cell lung cancer cell A549, large cell lung cancer cell NCI-H460, lung squamous cell carcinoma cell HTB-8 and human lung squamous cell carcinoma cell QG-5) and human normal liver cell L02 were inoculated in On a 96-well culture plate, the inoculum volume per well was 3000-4000 cells / 100uL and 6000 cells / 100uL respectively; aseptically collected 15 mL of venous blood from healthy blood donors, anticoagulated with heparin, and separated mononuclear cells by Ficoll density gradient centrifugation. A single cell suspension was prepared with RPMI1640 containing 10% fetal bovine serum, adjusted to a cell concentration of 2×105 cells / mL, and inoculated in a 96-well culture plate, 100 uL per well. After 24 hours of cell culture on each of the above-mentioned culture pl...

Abstract

The invention discloses an application of polyflavanostilbene A in preparation of medicaments for treating lung cancer. The compound shows good anti-lung cancer activity, can be used for preparing anti-lung cancer medicaments and belongs to the technical field of new uses of the medicaments. The polyflavanostilbene A can significantly inhibit non-small cell lung cancer cells A549, large cell lung cancer cells NCI-H460, lung squamous carcinoma cells HTB-8 and human lung squamous cell carcinoma cells QG-5, which are cultured in vitro, realize a smaller inhibition effect against human normal liver cells LO2 and peripheral blood lymphocytes and show obvious selectivity. The use of the polyflavanostilbene A in the preparation of the medicaments for treating the lung cancer, disclosed by the invention, belongs to the first disclosure, the framework type belongs to the brand new framework type, and the strong inhibition activity against the cells of the lung cancer is further unexpected.

Description

technical field [0001] The present invention relates to a new application of compound Polyflavanostilbene A, in particular to the application of Polyflavanostilbene A in the preparation of drugs for treating lung cancer. Background technique [0002] Malignant tumors are diseases that seriously threaten human life and health. Chemotherapy drugs commonly used in clinical practice can greatly damage normal tissues and cells while killing tumor cells, which limits its application. It has become the direction and urgent task of current anticancer drug research to find highly efficient and low toxic drugs for treating tumors. Finding high-efficiency, low-toxic anticancer drugs has been considered an effective way. [0003] The present invention has confirmed through experiments that Polyflavanostilbene A has significant inhibitory effect on non-small cell lung cancer cell A549, large cell lung cancer cell NCI-H460, lung squamous cell carcinoma cell HTB-8 and human lung squamous ...
