Abstract

The present invention relates to indole and 2,3-dihydroindole derivatives having formula (I) any of its enantiometers or any mixture thereof, or an acid addition salt thereof, wherein A, R<1>, R<2>, R<3>, W, X, Y and Z are as described in the description. The compounds are potent serotonin reuptake inhibitors and have 5-HT1A receptor antagonistic activity.

Description

Indoles and 2,3-indolin derivatives, their preparation and purposes

The present invention relates to new indoles and 2,3-indolin derivatives, this compound be effective serotonin reuptake inhibitor, contain the pharmaceutical composition of these compounds and their treatment to serotonin reuptake transporter restraining effect or 5-HT _1AThe functional disorder of receptor antagonism sensitivity or the purposes of disease.The compounds of this invention is also to 5-HT _1AAcceptor has antagonistic activity, and is considered to be specially adapted to the treatment of dysthymia disorders.

Background technology

Compare with first-generation antidepressant drug (tricyclic compound and nonselective MAO inhibitor), selective serotonin (or 5-TH) reuptake inhibitor (SSRI) is showing bigger progress in treatment aspect the dysthymia disorders as fluoxetine, paroxetine, Sertraline, fluvoxamine and citalopram because the side effect that they have still less and severe degree less.The side effect that first-generation antidepressant drug causes is so serious, makes some patients withdraw from treatment.

Used SSRI and all other antidepressant drugs all have a serious defective, promptly must could produce result of treatment through the treatment of several weeks.The hysteresis of drug effect starting is a serious problem, especially to treatment intensive patients with depression and the patient that introgression is arranged.In addition, there is 1/3rd patient insensitive to SSRI.

The electrophysiology experiment of mouse shows, the acute administration of SSRI can reduce the neuronic excitement of 5-HT of dorsal suture core in the rodent brain, can make the neuronic agonist activity normalizing of 5-HT (Arborelius with the SSRI continued treatment, L. wait the people, Naunyn-Schmiedeberg ' s Arch.Pharmacol.1995,352,157; Gartside, people such as S.E., Br.J.Pharmacol.1995,115,1064; Chaput, people such as Y., Naunyn-Schmiedeberg ' s Arch.Pharmacol.1986,33,342).Show (somatodendritic) 5-HT that the recovery of 5-HT neurone agonist activity and body are tree-shaped in addition _1AThe mistake of autoreceptor quick relevant (Le Poul, people such as E., Naunyn-Schmiedeberg ' s Arch.Pharmacol.1995,352,141; Invernizzi, people such as R., Eur.J.Pharmacol.1994,260,243).

Therefore there is the people to propose, SSRI and a kind ofly can cause 5-HT _1AQuick or the medicament administration simultaneously that suppresses of the rapid mistake of acceptor under Feedback mechanism running, quick startup (Artigas, people such as F., Trends Neurosci.1996,19,387 that will cause antidepressant effect; De Vry, J.DrugNews Perspec.1996,9,270).

A kind of compound and 5-HT that suppresses serotonin reuptake transporter _1AThe effect of receptor antagonist Combined Preparation has carried out estimating (Innis, people such as R.B., Eur.J.Pharmacol.1987,143, p195-204 and Gartside, S.E., Br.J.Pharmacol.1995,115, p1064-1070 in some researchs; Blier, people such as P., Trends Pharmacol.Sci.1994,15,220), in these researchs, find 5-HT _1AReceptor antagonist can stop the reduction by the caused agonist activity of acute administration of serotonin reuptake inhibitor.

In addition, unite use pindolol (a kind of well-known 5-HT _1AAcceptor and beta-adrenoceptor antagonists) and the treatment of SSRI in clinical trial, obtained evaluation, it is reported that patient's mental state obtains significant the improvement within a week.In addition, to the insensitive patient of used anti depressant medication, pindolol and SSRI Combined Preparation also demonstrate good effect (people such as Artigas F., Arch.Gen.Psychiary, 1994,51, p248-251 and Blier, people such as P., J.Clin.Phychopharmacol.1995,15, p217-222).

In several patents of having applied for, comprised uniting and used 5-HT _1AAntagonist and serotonin reuptake inhibitor are treated dysthymia disorders (seeing EP-A2-687472 and EP-A2-714663).

In EP-A1-529462, disclose some have below general formula 1,4-benzodioxan derivative:

Wherein, B is the optional indol-3-yl that replaces, and Q is C _nH _2n, wherein n is 1,2,3,4,5 or 6.It is said that these compounds have serotonin agonist activity and serotonin antagonistic action and serotonin reuptake transporter and suppress active, can be used as anxiolytic, thymoleptic, antihypertensive drug and cerebral protective agent.

In patent US 5200948, people such as Perregaard disclose 2 of relevant indoles with following formula, indazole, 2-indolone and they, the 3-dihydro derivative: Wherein X be-CH-,-CH ₂-,-NH-or-CO-; Ar is Wherein Y is O or S, Z be O, S or-CH-, and n is 1,2 or 3.These compounds are valuable 5-HT _1AReceptors ligand.

Goal of the invention

The purpose of this invention is to provide and have effective serotonin reuptake transporter and suppress active and 5-HT _1AAcceptor has the compound of antagonism performance, and this compound can be used as the medicine of fast-acting, and treatment emotionality mental disorder is as dysthymia disorders.

Table 3 ^*Reference compound

According to Sanchez, people such as C., Eur.J.Pharmacol., 1996,315, the described measuring method of pp245 is also to the 5-HT of the present invention-a little compounds _1AThe effect of acceptor has been carried out measuring in the body.In the method, by measuring to the syndromic inhibition ability of 5-MeO-DMT inductive 5-HT, the antagonistic action of confirmed test compound.

It is active and to 5-HT that The compounds of this invention has valuable serotonin reuptake inhibitor _1AThe antagonistic activity of acceptor.Therefore The compounds of this invention can be used for treatment to serotonin reuptake transporter restraining effect or 5-HT _1AThe disease of receptor antagonism sensitivity or functional disorder.Disease to serotonin reuptake transporter restraining effect sensitivity is known in the art, comprises the emotionality mental disorder, as dysthymia disorders, and psychosis, anxiety disorder comprises general anxiety disease, Phobias and mandatory symptom or the like.

As explained above, the 5-HT of The compounds of this invention _1AReceptor antagonist activity can be offset negative feedback mechanism by the serotonin reuptake transporter restraining effect, and inhibiting the repairing really of the serotonin reuptake transporter of The compounds of this invention is expected to improve thus.

Therefore, claimed compound is specially adapted to the fast-acting medicine as the treatment dysthymia disorders, and these compounds can also be used for the treatment of now using the insensitive dysthymia disorders of SSRI. Pharmaceutical preparation
