Embodiment 1

[0026] A pharmaceutical composition for increasing the susceptibility of antibiotics, the pharmaceutical composition comprising antibiotics and nightshade, the mass ratio of antibiotics and nightshade in the pharmaceutical composition, and the types of antibiotics are shown in Table 1.

[0027] The preparation method of the present embodiment pharmaceutical composition is:

[0028] (1) Grind the nightshade fruit into a coarse powder, add 6 times the amount of water, stir and extract at 20°C for 0.5-4 hours, extract twice, and use high performance liquid chromatography to monitor the content of solanine in the extract during the extraction process content, to ensure that the content of solanine in the obtained freeze-dried powder is 3-6mg / g, stop the extraction when reaching the corresponding content, combine the extracts, filter, centrifuge, put the centrifugate into a freeze-drying box, freeze-dry, extract and grind into powder , obtain the fine powder of crossing 200 mesh si...

Embodiment 2～7、 comparative example 1～2

[0032] The pharmaceutical compositions of Examples 2-7 include antibiotics and Solanum nigrum, and the mass ratio of antibiotics and Solanum nigrum in the pharmaceutical composition, and the types of antibiotics are shown in Table 1. Comparative Example 1 did not contain black nightshade, and Comparative Example 2 did not contain antibiotics.

[0033] The preparation method of the pharmaceutical composition of Examples 2-7 and Comparative Examples 1-2 is the same as that of Example 1.

Abstract

The invention relates to an application of solanum nigrum or a solanum nigrum extract to increasing sensitivity of antibiotics or antitumor drugs, and belongs to the technical field of drugs. Throughresearches, the inventor finds that the solanum nigrum or the solanum nigrum extract is combined with the antibiotics or the antitumor drugs for use, so that the sensitivity of the antibiotics or theantitumor drugs can be improved, the dosage can be reduced, the using safety of the drugs can be improved, and the treatment time can be prolonged. A pharmaceutical composition can intervene in DNA abnormal methylation and histone modification mechanisms based on the solanum nigrum or the solanum nigrum extract, and can be used for treating drug resistance generated by the antibiotics or the antitumor drugs. According to the invention, a new solution is provided for the drug resistance of the existing antibiotics or the antitumor drugs, the life cycle of the existing drugs is fully utilized and prolonged, and the current medical industry level and the current medical investment situation are better met from a medical economics principle.

Description

technical field [0001] The invention relates to the application of nightshade or nightshade extract in increasing the sensitivity of antibiotics or antitumor drugs, and belongs to the technical field of medicine. Background technique [0002] Antibiotics and antineoplastic drugs are the main means of treating infectious diseases and tumors respectively. However, due to the evolution mechanism of bacteria and tumors themselves, as well as the long-term use of large doses of antibiotics and antineoplastic drugs, the problem of bacterial and tumor drug resistance is intensifying. [0003] Natural medicines are rich in biologically active substances. A large number of studies have shown that scientific compatibility of traditional Chinese medicine and western medicine can synergize, increase sensitivity, reduce dosage, and reduce toxic and side effects. Combining traditional Chinese medicine with antibiotics and antineoplastic drugs may play unique advantages in improving bacter...
