Abstract

The invention relates to an organic amine salt of a stilbene derivative, a preparation method, an application and a pharmaceutical composition thereof. The present invention provides various organic amine salts of stilbene derivatives. Its preparation method is to react stilbene derivatives with ammonia or organic amine compounds to generate corresponding organic amine salts. The compound of the present invention can be used to prepare medicines for preventing and treating tumors and precancerous lesions, and medicines for treating connective tissue diseases or skin diseases; it can be prepared into various oral, injection and external preparations. The water solubility of the compound of the present invention is greatly increased compared with its parent compound stilbene derivative, so the dosage is small and the curative effect is good.

Description

Technical field: [0001] The present invention relates to various organic amine salts of stilbene derivatives, a preparation method thereof and an application for preparing drugs for preventing and treating tumors and precancerous lesions, and preparing drugs for treating connective tissue diseases or skin diseases. The present invention also relates to a pharmaceutical composition containing an organic amine salt of a stilbene derivative. Background technique: [0002] Stilbene derivatives are known antineoplastic drugs. Regarding stilbene derivatives and their preparation methods, GB2010836 first reported (December 21, 1978), and US4326055 on April 20, 1982 further reported their preparation methods and their clinical application prospects. The stilbene derivatives can prevent and treat benign and malignant tumors and precancerous lesions when used locally or systemically, and have significant antitumor effects. This kind of compound can be made into various types of prep...
