Abstract

This invention relates to tectoridin digital isostere, they has following constitutional general formula, X is oxygen or NH. It has restraining effect ot cancer cell, and can be used to prepare anti tumor medicine, this invention also discloses its preparation method.

Description

Roofirisrhizome flavin non polar isostere and method for making thereof and purposes
Technical field
The present invention relates to isostere and method for making and their application in the preparation antitumor drug of a class tectorigenin.
Technical background
Tectorigenin is the main active ingredient of Chinese medicinal materials blackberry lily, has following structure:
Figure A20061004066500041
Blackberry lily is the dry rhizome of Iridaceae blackberry lily platymiscium blackberry lily [Belamcanda chinensis (L.) DC], has effect clearing heat and detoxicating, the relieve sore throat dissolving phlegm, is mainly used in diseases such as throat lung carbuncle, productive cough asthma, is the key medicine of treatment larynx numbness pharyngalgia.Because tectorigenin has estrogen-like effects, thereby when tectorigenin and oestrogenic hormon acted on target organ simultaneously, the two competed conjugated estrogen hormone acceptor, thereby alleviates estrogenic short cel l proliferation, reduces the pathogenesis of cancer danger relevant with oestrogenic hormon.Simultaneously tectorigenin also has to a certain degree restraining effect to non-estrogen-dependent tumour, as tectorigenin HL-60 cell (leukemia cell) is had very strong restraining effect.Tectorigenin also has to a certain degree restraining effect to the propagation of BGC cell (adenocarcinoma of stomach).
The experimentation on animals of Thelen P et al. shows that tectorigenin has the effect of obvious suppression tumour, finds that it can be used as the medicine of prevention and treatment people's prostate cancer.Saratikov; A.S.et al. studies show that; polyols such as tectorigenin can suppress hepatocellular necrosis; stop intrahepatic fat and proteinic unbalance; make the active normalizing of transaminase and glutamyl transferring enzyme; prevented the development of hepatic fibrosis, the effect that play the protection liver, recovers liver function.Act on the liver cell of mouse with tertbutyl peroxide, take tectorigenin then, find that tectorigenin can protect mouse to avoid the infringement of tertbutyl peroxide inductive liver cancer cell.Intracellular active oxygen is one of factor that causes cell carcinogenesis, tectorigenin can be removed active oxygen on the one hand, can increase the active of superoxide dismutase, catalase and glutathione peroxidase and their protein level on the other hand, strengthen the ability of cell removing active oxygen.Tectorigenin also has the effect of fine anti-hepatic fibrosis.
Summary of the invention
The objective of the invention is to the tectorigenin is guide's thing, the isostere that synthesizes a series of tectorigenins by some ultimate principles of medicinal design, on the basis of further investigation structure activity relationship, find the new drug that activity is higher, toxic side effect is lower, and the method for making of Roofirisrhizome flavin non polar isostere is provided.
Technical scheme of the present invention is as follows:
The isostere of one class tectorigenin, they have following general structure:
