Abstract

The invention discloses an oxo-bridged bicyclo-heptylene sulfonamides compound containing different alkyl chain lengths, as well as a preparation method and application thereof, and belongs to the technical field of medicines. 3-(4-hydroxycyclohexyl phenyl)-4-(4-alkoxy phenyl)-furan and a phenylethylene sulfonamide derivative are adopted as raw materials, no catalyst is needed, the raw materials are reacted at 90 DEG C for 8 hours, and the oxo-bridged bicyclo-heptylene sulfonamides compound containing the different alkyl chain lengths is obtained through one-step preparation. The action mode of the oxo-bridged bicyclo-heptylene sulfonamides compound is different from the action mode of existing anti-breast cancer drug tamoxifen, and the compound not only can be used for effectively inhibiting the growth of a breast cancer cell MCF-7, but also has favorable estrogen receptor alpha down-regulation activity equivalent to fulvestrant, and shows an application prospect of the compound in breast cancer therapy.

Description

technical field [0001] The invention belongs to the technical field of medicine, and relates to a synthesis method of oxo-bridged bicycloheptene sulfonamide compounds containing different alkyl chain lengths and its application in anti-breast cancer drugs. Background technique [0002] Among many cancers, breast cancer is one of the most common malignant tumors threatening women's health worldwide. Although five-year survival rates for the disease have improved in developed countries, the incidence remains high and patients tend to be younger. At present, hormone replacement therapy is mainly used clinically. Although it has made a major contribution to the treatment of ER-positive breast cancer, long-term use of estrogen drugs, such as tamoxifen, will produce a series of side effects such as drug resistance. , which seriously hinders the development of estrogen replacement therapy. Researchers have speculated that some mechanisms of drug resistance arise, such as ERα rece...
