Problems solved by technology

Endogenous estrogen plays a major role in the occurrence of breast cancer, so estrogen receptor (ER) blockers have targeted therapeutic significance. In addition, epidermal growth factor receptor (EGFR) and ErbB2 (HER-2 / neu) is also an important part of the most deeply studied growth factor receptor system in the field of breast cancer, but so far none of these can really play a role in inhibiting breast cancer

Embodiment Construction

[0013] Below in conjunction with embodiment the present invention is described in more detail.

[0014] In the in vivo experiment, the cultured human breast cancer cell line ZR-75-30 was diluted in the medium to make the cell density 2.5×10 7 Each nude mouse was subcutaneously inoculated with 0.2 mL under the fat pad of the second papilla on the right side. After the inoculation, it was reared in a breeding room without special pathogens, and the tumor growth was regularly observed and recorded until the tumor volume was nearly 100mm. 3 When (measure the volume with a vernier caliper, the calculation formula: V=a×b 2 / 2, where a is the long diameter of the tumor, and b is the short diameter of the tumor), the initial tumor volume and initial body weight were recorded, administered in groups, and the in vivo experiment was divided into 6 groups, 6 rats / group, a total of 36 rats.

[0015] Negative control group: 0.5% CMC-Na physiological saline group.

[0016] Tuspinine deriva...

Abstract

The invention relates to application of thaspine derivative HMQ1611 in inhibition of mammary cancer. In an integral level, a mammary cancer ZR-75-30 tumor transplantation tumor model is built on the basis of a nude mouse transplantation tumor model, the inhibition effect of the thaspine derivative HMQ1611 on mammary cancer is researched, and then the mammary cancer resistance passageway of the thaspine derivative HMQ1611 is also researched, thus the inhibition effect of the thaspine derivative HMQ1611 on ER (estrogen receptor)-dependent mammary cancer is verified, and the influence of the thaspine derivative HMQ1611 on ER passageway of mammary cancer cells is also verified, thereby showing that the thaspine derivative HMQ1611 can truly inhibit mammary cancer.

Description

technical field [0001] The invention belongs to the field of compound pharmacological action and molecular biology technology, and specifically relates to the application of a tospinine derivative HMQ1611 for inhibiting breast cancer. Background technique [0002] Breast cancer is a common malignant tumor that threatens the health and life of women all over the world, and its incidence rate ranks first among urban female tumors in my country. Epidemiological data show that with the development of society, the incidence of breast cancer will continue to increase. The development of new anti-mammary tumor drugs will be one of the important means for humans to overcome breast tumors. In recent years, with the development of immunology and molecular biology, people have a more in-depth understanding of the receptors, genes and signal transduction in the process of tumor formation, and the targeted therapy developed on this basis has achieved breakthrough results. Progress, res...
