Abstract

The invention discloses an application of an ingenane diterpene compound in preparation of antitumor drug. The ingenane diterpene compound is one or more of the ingenane diterpene compound shown in a formula (1). The ingenane diterpene compound can obviously inhibit the propagation activity of breast cancer cells, compared with a traditional tumor therapeutic method, tumor inhibitory effect is good, toxic and side effects are little, targeting property is strong, the ingenane diterpene compound has no damage to normal cells, security can be guaranteed at maximum degree, the ingenane diterpene compound provides a latent novel medicine development purpose for treating breast cancer, and can be a further research as an anti-breast cancer candidate medicine.

Description

technical field [0001] The present invention relates to the application of an ingenoid compound, in particular to the application of an ingenoid compound in the preparation of antitumor drugs. Background technique [0002] Cancer is the number one malignant disease that seriously threatens human life, and breast cancer has become one of the cancers that threaten women's health the most. With the development of modern society and economy, unhealthy living environment factors caused by various social problems and family problems have increased the incidence of female breast cancer year by year. At present, there are an average of 1.3 million new breast cancer cases in the world every year, and in recent years there have been continuous An upward trend. In recent years, the growth rate of the incidence of breast cancer in my country is 1-2 percentage points higher than that of high-incidence countries, and it shows a clear trend of rejuvenation. [0003] Breast cancer is a gene...
