Novel aryl-with heteroaryl-piperazine
Invention field
The present invention relates to novel aryl-, relate to the purposes of these compounds, relate to the pharmaceutical composition that comprises these compounds, also relate to the methods of treatment of these compounds of employing and composition as pharmaceutical composition with the heteroaryl piperazine.The compounds of this invention shows high selective binding affinity to histamine H 3 receptor, shows to have histamine H 3 receptor antagonism, anti-excitement or agonist activity.Consequently, these compounds can be used for treating disease and the obstacle that relates to histamine H 3 receptor.
Background of invention
Knew the existence of histamine H 3 receptor before several years already, this receptor is the interest place of present novel drugs exploitation.Recently, human histamine H 3 receptor is cloned.Histamine H 3 receptor is a kind of presynaptic autoreceptor, is arranged in maincenter and peripheral nervous system, skin and organ, and for example lung, intestines mainly are spleen and gi tract.Prompting on evidence recently, the H3 acceptor shows the intrinsic constitutive activity, in the external and body all be so (that is to say, do not have agonist in the presence of also be activated).The compound that serves as inverse agonist can suppress this activity.Histamine H 3 receptor has been proved to be the release of regulating histamine and other neurotransmitters, for example thrombotonin and vagusstoff.Therefore histamine H 3 receptor antagonists or inverse agonist will be increased the release of these neurotransmitters in brain by expection.On the contrary, the histamine H 3 receptor agonist causes the inhibition that biosynthetic inhibition of histamine and histamine and other neurotransmitters discharge, for example thrombotonin and vagusstoff.It may be the important medium of neuron activity that histamine H 3 receptor agonist, inverse agonist and antagonist have been pointed out in these discoveries.Therefore, histamine H 3 receptor is the important goal of novel treatment.
The compound similar to The compounds of this invention disclosed in the past, referring to J.Med.Chem.1999,42,336, J.Med.Chem.1992,35,2369, DE 2804096, J.Org.Chem.1996,61,3849, Bull.Soc.Chim.Fr.1969,319, WO 00/66578, WO 99/21845 and J.Med.Chem.1968,11 (6), 1144-1150.But, these reference had not both had openly, have not pointed out these compounds may have histamine H 3 receptor antagonism or agonist activity yet.
Some publications disclose the preparation and the purposes of histamine H 3 agonists and antagonist.Their great majority are imdazole derivatives.But, the no imidazole ligands of some histamine H 3 receptors had been described recently (for example referring to Linney et al., J.Med.Chem.2000,43,2362-2370; US 6,316,475, WO 01/66534 and WO 01/74810).But, these compounds structurally are different from The compounds of this invention.
In view of the interest of this area, will make very desirable contribution to this area with the interactional compounds of histamine H 3 receptor to histamine H 3 receptor agonist, inverse agonist and antagonist.The present invention is based on following discovery and for this area provides a kind of like this contribution, i.e. the aryl of a class novelty-histamine H 3 receptor is had high specificity affinity with heteroaryl-piperazine.
Because the interaction of they and histamine H 3 receptor, The compounds of this invention can be used for treating illness and obstacle widely, and wherein the interaction with histamine H 3 receptor is useful.Thereby these compounds for example can be used for the treatment of the disease of central nervous system, peripheral nervous system, cardiovascular systems, pulmonary system, gastro-intestinal system and endocrine system.
