Problems solved by technology

The activation of NF-κB leads to the expression of a large number of anti-apoptotic genes, which greatly weakens the anti-tumor effect of tumor necrosis factor, and also leads to inflammation, causing tumor recurrence, metastasis and other side effects

Abstract

The invention relates to an antitumor medicine composition and application thereof. The composition comprises maslinic acid or physiologically acceptable salts or derivatives thereof and tumor necrosis factor alpha used in combination. The acting effects of the composition are superior to the added effects of each medicine used individually. The combination use can effectively reduce the toxic and side effects produced by the tumor necrosis factor alpha used individually, so that the composition used in combination can be used for treating tumor and related diseases.

Description

technical field [0001] The present invention relates to an anti-tumor pharmaceutical composition and its application, in particular to an anti-tumor MA-TNFα pharmaceutical composition and its application. Background technique [0002] The incidence of cancer is still increasing year by year, and cancer is currently the number one cause of death. Although, intensive and extensive research and investigation in recent years have provided a relatively in-depth understanding of the mechanism of tumor generation. In theory, it clarifies the various processes that can control the development of tumors by various means. In practice, many different anti-tumor drugs that act on different stages of cancer through different mechanisms have been discovered and accumulated. Especially in the past three decades, many anti-tumor drugs have entered clinical practice one after another. However, tumor is a complex disease caused by many factors. Practice has proved that the therapeutic eff...
