Abstract

The invention discloses the application of a 4-1H-1,2,3-triazole-beta-lactam derivative. The 4-1H-1,2,3-triazole-beta-lactam derivative is used for preparing a medicine for resisting human brain glioma and colon cancer. The 4-1H-1,2,3-triazole-beta-lactam derivative has better biological activity, and is proved to have stronger propagation inhibitory activity for the human brain glioma (U87mG) and colon cancer tumor (LS-174T) cells by in vitro activity test. Therefore, the 4-1H-1,2,3-triazole-beta-lactam derivative is a potential antitumor drug, and has the application of preparing antitumor pharmaceutical preparation.

Description

technical field [0001] The invention relates to the use of a 4-position-1H-1,2,3-triazole-β-lactam derivative, and the effect of the compound on human glioma (U87mG) and colon cancer (LS-174T) tumors Cytotoxic activity of cells. Such compounds are found to have certain biological activity of inhibiting the growth of the tumor cells, and have potential application as antitumor drugs. Background technique [0002] Cancer is a serious threat to human life and health, and is one of the diseases with the highest mortality rate. Anticancer drugs have always been a hot area of ​​drug research and development. Due to the complexity and particularity of the mechanism of cancer, finding anticancer drugs with high selectivity, high efficiency and low side effects is a very challenging topic in life sciences and requires scientific research. The joint exploration and long-term efforts of the authors. [0003] Glioma is the most common primary intracranial tumor. It is an infiltrating...
