Description

Combined medicine for treating liver cancer
Technical Field
The invention relates to the field of anti-cancer drugs, in particular to a combined drug for treating liver cancer.
Background
Liver cancer is a common malignant tumor in the digestive system, and is generally classified into primary liver cancer and secondary liver cancer. Primary liver cancer is classified into diffuse, lump, nodular and small cancer types, and clinical diseases often include liver pain, abdominal distension, asthenia, liver palms, spider nevus, jaundice and ascites. The secondary liver cancer is also called metastatic liver cancer, and malignant tumors generated in various parts of the whole body of a human body are accumulated to the liver to form the secondary liver cancer.
Sorafenib (chemical name: 4- (4-3- [ 4-chloro-3- (trifluoromethyl) phenyl ] ureidophenoxy) -N2-methylpyridine-2-carboxamide-4-tosylate), an oral multi-target kinase inhibitor, is a first-line treatment drug for advanced liver cancer, but sorafenib is only effective on 30% of patients with advanced liver cancer and only prolongs the median survival time for 3 months. Most patients are sensitive to sorafenib early, but after a period of treatment with sorafenib, the liver cancer recurs again and even progresses, the main reason for this being the development of sorafenib resistance. Although the curative effect of the sorafenib is limited by the drug resistance, the safety tolerance and the controllability of side effects of the sorafenib drug cause the sorafenib drug to be a first-line targeted drug for treating the liver cancer. In order to overcome the drug resistance of sorafenib, a combined drug scheme is urgently needed to be researched to enhance the curative effect of sorafenib.
Avasimibe (chemical name: N- (2, 6-diisopropylphenoxy) sulfonyl-2- (2,4, 6-triisopropylphenyl) acetamide) is an inhibitor of SOAT, and inhibits liver cancer by inhibiting synthesis of structural lipid and reducing fluidity of cell membrane, but unfortunately, avasimibe has very limited benefit on liver cancer patients.
At present, the combination of sorafenib and avasimibe for treating liver cancer does not exist.
Disclosure of Invention

Detailed Description
Experimental example 1 Sorafenib in combination with avasimibe inhibits hepatoma cells in vitro.
1. Experimental methods
1.1 cells for experiments
Liver cancer cell line: HepG2 liver cancer cell, HUH7 liver cancer cell
1.2 Experimental treatment: the hepatoma cell lines were treated with Control (Control), sorafenib (10 μ M), avasimibe (20 μ M), sorafenib (10 μ M) + avasimibe (20 μ M), respectively.
1.3, detection:
(1) CCK8 detection of cell number changes
After 3 days of experimental treatment, CCK8 is adopted to detect the proliferation condition of the liver cancer cells, and the result uses compusyn to calculate the synergy index.
(2) Observation of cell clone formation
After 7 days of experimental treatment, the number of clones was observed using crystal violet staining.
2. Results of the experiment
The results of the CCK8 testing the cell number change after different drug treatments are shown in FIG. 1, and can be seen from FIG. 1: the relative cell proliferation ratio of the sorafenib and avasimibe group is significantly lower than that of other groups. From fig. 1 it can be seen that: sorafenib and avasimibe in a molar ratio of 1: 2, the synergy indexes aiming at HepG2 liver cancer cells and HUH7 liver cancer cells are both less than 1, so that the sorafenib and the avasimibe can synergistically inhibit the proliferation of the liver cancer cells.
The crystal violet staining result is shown in figure 2, and it can be seen from figure 2 that the relative cell clone number of the sorafenib and avasimibe group is obviously less than that of other groups, so that the sorafenib and avasimibe group can be judged to be capable of effectively inhibiting the proliferation of liver cancer cells, and the anticancer effect of the sorafenib and avasimibe group is obviously better than that of sorafenib or avasimibe used alone.
3. Conclusion
Compared with the independent use of sorafenib or avasimibe, the combined use of sorafenib and avasimibe has better capability of inhibiting the proliferation of liver cancer cells in-vitro experiments, and the sorafenib and the avasimibe have synergistic effect.
Experimental example 2 Sorafenib and avasimibe in vivo inhibition of hepatoma cell proliferation
1. Experimental methods
1.1 constructing an animal model: mice were injected subcutaneously with HepG2 liver cancer cells (5.0X 10)6Individual cells).
1.2 drug configuration: sorafenib and avasimibe were dissolved with 20% PEG300, 5% Tween80, 5% DMSO and saline.
1.3 Experimental treatment: one week after injection, tumors were approximately 180mm in size3The mice are randomly divided into a control group, a sorafenib group, an avasimibe group and a sorafenib combined avasimian group, and each group comprises 8 mice. Control group (20% PEG300, 5% Tween80, 5% DMSO and normal saline, intraperitoneal injection, once a day), sorafenib group (10mg/kg, intraperitoneal injection, once a day); avasimibe group (15mg/kg, intraperitoneal injection, once a day); sorafenib (10mg/kg i.p., once daily) + avasimibe (15mg/kg i.p., once daily). Tumor diameter was measured every three days for 14 days. When the maximum diameter of the tumor reaches 1.5-2.0cm, the nude mice are killed by removing the neck, the tumor is stripped, the weight is measured, the tumor size is measured, and the volume is calculated: v ═ W (L ═ W)2) And/2, wherein L and W represent length and width.
2. Results
The tumor inhibition effect of each experimental group is shown in FIG. 3, the tumor weight statistics of each group are shown in Table 1 and FIG. 4, and the tumor volume statistics of each group are shown in Table 2 and FIG. 5.
TABLE 1 tumor weight changes
Figure BDA0003257121900000041
TABLE 2 tumor volume changes
Figure BDA0003257121900000051
As can be seen from tables 1-2 and FIGS. 3-5: in a nude mouse tumorigenesis experiment, compared with the sorafenib group or the avasimibe group which is used alone, the combination of the sorafenib and the avasimibe group can remarkably reduce the weight of the liver tumor and remarkably reduce the volume of the liver tumor.
3. Conclusion
In vivo experiments, sorafenib and avasimibe were mixed in a mass ratio of 10:15 compared with the single drug sorafenib or the single drug avasimibe, the combination can effectively inhibit the growth of liver cancer cells, reduce the weight and volume of tumors and has the synergistic effect.
In conclusion, the invention adopts the following steps that the molar ratio is 1: 2 (mass ratio 10: 22) is combined with avasimibe to be used for in vitro inhibition experiments of liver cancer cells, and the combination has obvious coordination and synergism effects, and because the in vivo experiments have more influence factors including drug absorption, drug metabolism, drug half-life period and the like, the in vivo and in vitro drug ratio can be different, and the invention adopts the following components in mass ratio of 10: the sorafenib and the avasimibe used for animal in-vivo inhibition experiments of liver tumors also show that the combination of the sorafenib and the avasimibe can remarkably inhibit the proliferation of liver cancer cells, and has good clinical application prospect.
