Abstract

The invention discloses a new application of isojacareubin. The new application is meant that isojacareubin as an active ingredient is used in preparation of an antitumor pharmaceutical preparation. Pharmacological tests prove that, isojacareubin has an obvious inhibition effect on growth of U87 human brain glioma cell lines, BXPC-3 human pancreatic cancer cell lines, NCI-2126 human lung cancer cell lines, PANC-1 human pancreatic cancer cell lines, A549 human non small cell lung cancer cell lines, AGs human gastric cancer cell lines, A375 human melanoma cell lines, MCF-7 human breast cancer cell lines, MDA-MB-231 human breast cancer cell lines and SMMC-7721 human liver cancer cell lines, has significant antitumor activity, can be expected to be used as the active ingredient for the preparation of the antitumor pharmaceutical preparation, and has medicinal prospects.

Description

technical field [0001] The invention relates to a new application of isobrazirin schicin, which belongs to the technical field of natural compound application. Background technique [0002] Malignant tumors are currently the main diseases that threaten human health and life. Cancer is the second leading cause of death after cardiovascular disease in most developed countries. Tumor is also a major disease that seriously endangers the health of our people. Our country's tumor research has also been valued by the government. Cancer control has become one of the key points of our country's health strategy. [0003] Tumor treatments include surgery, radiation and chemotherapy. The outstanding problems of the current clinical application of anti-tumor drugs are low efficiency, poor selectivity (high toxicity) and insensitivity to drug-resistant tumors. In addition, recurrence and metastasis are also difficulties in tumor treatment. Therefore, it is a major research topic for p...
