Abstract

The invention discloses a ferrocene-bridged bicyclic-[2.2.1]-heptyl diene compound that contains N-hydroxy-(i)N-benzene succinic amide or a similar structure. 3-(4-hydroxyphenyl)-4-suberic nonacylanilino-furan or similar analogs and a ferrocene vinyl sulfonate derivative are used as raw materials, and a solvent and a catalyst are not needed; the raw materials are reacted for 3 hours at 90 DEG C through one step to obtain a ferrocene-bridged bicyclic-[2.2.1]-heptyl diene compound that contains a suberic nonacylanilino group. According to an in vitro experiment, compared with a current anti-cancer drug Tamoxifen, the novel ferrocene-bridged bicyclic-[2.2.1]-heptyl diene compound has stronger inhibitory activity on hormone-dependent breast cancer MCF-7 cells and non-hormone-dependent breast cancer MDA-MB-231 cells, and has no toxicity on normal VERO cells while the current anti-cancer drug Tamoxifen has toxicity on normal VERO cells.

Description

technical field [0001] The present invention relates to a class of anti-breast cancer activity containing N -Hydroxy- N Preparation and application of ’-phenyl suberamide (SAHA) or ferrocenyloxy bridge bicyclo-[2.2.1]-heptene compounds with similar structures. Background technique [0002] Breast cancer is one of the most common malignant tumors in women all over the world, and its incidence is increasing year by year in recent years, which seriously threatens women's life and health. According to the current development trend of breast cancer, it is estimated that the incidence of breast cancer will reach 2.64 million by 2030, and the number of deaths caused by breast cancer will reach 1.7 million. It is now considered that breast cancer is a precursor malignant tumor, and its growth has a very close relationship with endocrine hormones. Estrogen in particular plays a very important role in the development of breast cancer. Estrogen regulates the growth, differentia...
