Abstract
A substituted tetrahydroisoquinoline and its salts can be used to prepare the tumor-reversing medicine with multi-drug resistance (MDR). Its advantages are high activity and no calcified antagonist cardiovascular by-effect.
Description
Technical field the present invention relates to the tetrahydro isoquinoline derivative that the 2-amidino groups replaces, and it is used to prepare the purposes of medicine, specifically prepares the purposes of reverse multiple drug resistance of tumor medicine.
The background technology tumor is one of disease of harm humans life.Tumor can produce a kind of self-protective mechanism---drug resistance after accepting chemotherapeutic agent; drug resistance of tumor has become one of major reason of chemotherapy of tumors failure; solid tumor particularly; it is very difficult that chemotherapeutics arrives tumor tissues; drug resistance produces the back tumor cell can constantly discharge the extracellular with the chemotherapeutics that arrives target tissue; for the effect of offsetting drug resistance raising chemotherapeutic must improve dosage; this can increase the injury of chemotherapeutics to normal structure undoubtedly, and the drug resistance that therefore how to overcome tumor has become one of hot fields of current anti-tumor medicine research.Drug resistance of tumor can be divided into primary resistance (PDR) and multidrug resistance (MDR) two big classes, PDR only produces drug resistance to induced drug, and other medicines are not produced drug resistance, MDR is meant that then tumor cell is once certain chemotherapeutics is produced drug resistance, simultaneously to irrelevant on other structure, the also different medicine of the mechanism of action also produces chemical sproof phenomenon, and most of chemotherapeutics removes antimetabolite and induces generation PDR, all easily induces to produce MDR.The MDR reversal agents of clinical research at present is based on calcium antagonist, and wherein representing medicine is verapamil, and this class inversion agent has definite reverse curative effect, but it is not strong to exist the effect specificity, and reverse is active low, and is accompanied by serious cardiovascular side effects.Therefore it is active strong to seek reverse multiple drug resistance of tumor, and the low medicine of side effect becomes the technological difficulties of this research direction most critical.
Summary of the invention the object of the present invention is to provide a kind of purposes of tetrahydro isoquinoline derivative of new replacement, is the purposes of reverse multiple drug resistance of tumor specifically, and its cardiovascular side effects is less, safety is higher, is used to improve the curative effect of antineoplastic agent.
This seminar is that guide's thing carries out designs simplification in the eighties with natural tetrahydro isoquinoline compounds such as effective components of Chinese medicinal tetrandrine.In the research afterwards, seek by transformation in the process of new calcium antagonist, find that the benzyl tetrahydro isoquinoline compound that N-cyanogen amidino groups replaces has very strong reversion MDR activity, some chemical compound reversion MDR activity far is better than clinical inversion agent verapamil commonly used, and does not have the cardiovascular side effect.
Summary of the invention is as follows in detail:
