Description

4-[2-(artyl sulfo) benzyl]-1-aryl piperazine derivative and preparation method and application
Technical field
The present invention relates to a kind of 4-[2-(artyl sulfo) benzyl with antidepressant activity]-structure of 1-aryl piperazine derivative and its production and application, this technology belongs to the pharmaceutical chemistry field.
Background technology
Dysthymia disorders is a kind of common mental disorder, belong to affective disorder, along with rhythm of life is constantly accelerated, people's stress also increases gradually, and dysthymia disorders has become the common disease of modern society, high morbidity, and its sickness rate is soaring fast: according to incompletely statistics, at present whole world patients with depression has accounted for 3% one 5% of world population, almost see each age level, its morbidity is about 3% in the general population, in the patient population of general hospital polyclinic's health care service about about 10%; And in patient's (as cardiovascular diseases, diabetes) of chronic physical disease, that suffers from depressive disorder can but, have only the patient of considerably less ratio identified up to 20%.By pharmacological agent, wherein about 2/3 patient can obtain different curative effects, as the end in time discern and treat they will bring more serious consequence (as commit suiside, disabled, too much medical resource waste etc.).The World Health Organization predicts the year two thousand twenty, and dysthymia disorders will become the 2nd big cause that causes deformity.
Nineteen fifty is for tricyclic antidepressant (TCA having occurred, Anticholinergic), 5-HT selectivity reuptake inhibitor class SSRI (Fluoxetine has appearred in the 1980's, Paroxetine, Sertaline, Citalopram, Fluvoxamine) because of its good antidepressant performance, replace TCA gradually and become leading product on the thymoleptic market, yet owing to the SSRI indirect action has nauseating in all 5-HT acceptors, anxiety, insomnia, sexual function side effect such as decrease, and maximum weakness is a lag-effect in clinical use, promptly generally after week antidepressant effect could appear at the 2-6 that begins to take medicine, therefore in order to seek safety, quick acting, the thymoleptic that side effect is little, the medicine scholars have carried out various trials.
The thymoleptic such as the NE/5-HT reuptake inhibitor SNRI (Venlaxine of some new role mechanism appearred in generation nineteen ninety so far, Milnacipran, Duloxetine, Nefezodone), selectivity oxidase inhibitor MAOI (Moclobe mide, Toloxatone), selective N E reuptake inhibitor NARI (Reboxetine), NE energy and specificity 5-HT energy antidepressive NaSSa (Mirtazapine), though these medicines are compared with the SSRI class, on curative effect and quick acting, be improved, but lag-phase in 1-2 week is still arranged, therefore very urgent to the drug research of quick acting more.
Reported first such as Artigas were with pindolol (blended 5-HT in 1993 1A/ beta-2 adrenoceptor antagonist) can significantly reduce lag-phase of SSRIS with the medication of SSRIS antidepressant medicament combination, strengthen antidepressant effect, patient symptom is significantly improved.Result of study subsequently shows, 5-HT 1AAntagonist WAY100635 and several SSRIS connection and medication also can show this effect.A kind of hypothesis of this phenomenon is thought it may is the 5-HT of preceding nerve synapse 1ATherefore the autonomous acceptor of nerve synapse 5-HT before the antagonistic action of autonomous acceptor can be blocked has increased the 5-HT concentration between the nerve synapse gap, thereby improves curative effect, reduces the lag-phase etc.
On this basis, present research focus mainly is with various 5-HT 1AThe primary structure of receptor antagonist or agonist primary structure and SSRIS is combined in the molecule and makes it 5-HT conducting band and 5-HT 1AAcceptor all has higher affinity, thereby brings into play dual antidepressant effect, and this kind idea is further extended, and has just formed so-called SSRI ' plus ' method.Under the guidance of this method, the compound that some new role mechanism occurred is in the clinical study stage at present, for example Flibanserin and Vilazodone, and they antidepressant effect can just occur after taking several days.
Summary of the invention
The object of the present invention is to provide a kind of 4-[2-(artyl sulfo) benzyl]-1-aryl piperazine derivative and preparation method and application, this compounds has 5-HT and 5-HT simultaneously 1AActivity can be used for preparing anti-depression drug.
