Abstract

The present invention relates to a quinine compound containing quaternary ammonium groups of the general formula I (disclosed in the specification), a preparation method thereof and a medical composition containing an effective dose of the compound of the general formula I, and in the general formula I, R1 and R2 are stated in the text. The composition can be used for the prevention and the treatment of diseases correlated with blocking choline receptors.

Description

A kind of quinine compounds and method for making and pharmaceutical use that contains quaternary ammonium group
Technical field contains the quinine compounds of quaternary ammonium group, particularly relates to the new compound of general formula I, and preparation method thereof, contain the application in the preparation anticholinergic agents of one or more these compound compositions and this compound.
Technical background vagusstoff (acetylcholine, ACh) be the neurotransmitter that cholinergic nerve tip (comprise Motor nerve fibre, vegetative nerve preganglionic fiber, parasympathetic ganglion after fiber and part sympathetic nerve postganglionic fibers) discharges, having very strong biological activity, is M-ChR (m receptor) and nAChR (n receptor) performance effect by acting on cholinergic receptor.The cholinergic receptor blocking agent medicine that to be a class play a role by the blocking-up cholinocepter is divided into M-cholinocepter blocking agent and N-cholinocepter blocking agent.Cholinocepter on the effector of M-cholinocepter blocking agent energy blocking-up maincenter and joint back cholinergic innervation, show as the plan mentation of nervus centralis and smooth muscle loosening, glandular secretion inhibition, platycoria, the rhythm of the heart speeds etc., has pharmacological action widely and clinical application.
At present, M-cholinocepter blocking agent substantially all is tropine Alkaloid and coromegine synthetic substance.Because its pharmacological action is extensive, use its in a certain respect do the time spent, the effect of others will show as side effect, especially intend the spirituality effect, this has just limited its application clinically, and therefore, anticholinergic should have certain selectivity, promptly keep its cholinolytic effect, reduce its maincenter and intend the spirituality side effect.
In existing document, do not see the report of the present invention's the quinine compounds that contains quaternary ammonium group so far as yet, and it is used to block cholinergic receptor and as the purposes of anticholinergic agents.
Summary of the invention the object of the present invention is to provide a kind of quinine class novel cpd that contains quaternary ammonium group in order to overcome the deficiency of existing medicine and technology.
Another object of the present invention is to provide the method for the quinine compounds that a kind of preparation contains quaternary ammonium group.
Another purpose of the present invention is to provide one or more to contain the pharmaceutical composition of this compound and pharmaceutically acceptable carrier.As: tablet, capsule, aerosol, sprays, injection, sustained release dosage etc.
A further object of the present invention is to provide the purposes of a kind of this compound as anticholinergic relative disease medicine.
In order to realize the present invention's purpose, the present invention takes following technical scheme:
The present invention relates to have the novel cpd of general formula I:
