摘要:
Novel compounds which interact with the histamine H3 receptor are defined. These compounds are particularly useful in the treatment of a variety of diseases or conditions in which histamine H3 interactions are beneficial. Thus, the compounds may find use, e.g., in the treatment of diseases of the central nervous system, the peripheral nervous system, the cardiovascular system, the pulmonary system, the gastrointestinal system and the endocrinological system. The novel compounds have a core consisting of a 6 membered aromatic ring containing at least one nitrogen atom and two carbon atoms in the ring and, at the remaining positions in the ring, there is either a carbon or a nitrogen atom.

摘要:
Novel aryl- and heteroarylpiperazines, use of these compounds as pharmaceutical compositions, pharmaceutical compositions comprising the compounds, and a method of treatment employing these compounds and compositions. The compounds show a high and selective binding affinity to the histamine H3 receptor indicating histamine H3 receptor antagonistic, inverse agonistic or agonistic activity. As a result, the compounds are useful for the treatment of diseases and disorders related to the histamine H3 receptor.

Novel substituted hexahydropyrrolo[1,2-a]pyrazines, octahydropyrido[1,2-a]-pyrazines and decahydropyrazino[1,2-a]azepines, use of these compounds as pharmaceutical compositions, pharmaceutical compositions comprising the compounds, and a method of treatment employing these compounds and compositions. The compounds show a high and selective binding affinity to the histamine H3 receptor indicating histamine H3 receptor antagonistic, inverse agonistic or agonistic activity. As a result, the compounds are useful for the treatment of diseases and disorders related to the histamine H3 receptor.
摘要:
A disubstituted piperazine compound having the formula ##STR1## wherein R.sup.1 is halogen, methoxy, C.sub.1-6 -alkyl or trifluoromethyl, and R.sup.2 is methyl or substituted C.sub.1-8 -alkyl, C.sub.3-8 -alkenyl or C.sub.3-8 -cycloalkyl, where substituents may be hydroxy-, keto- or oximino-groups in any position leading to a stable tertiary amine; or R.sup.2 is a straight or branched C.sub.1-8 -alkyl or C.sub.3-8 -alkenyl, which in any position may be substituted as above, but is terminally substituted with one of the following groups: cyano, optionally C.sub.1-4 -alkoxy-substituted C.sub.1-4 -alkoxy, dimethoxy, optiontionally substituted phenoxy, phosphonic acid, thienyl, furyl, oxazoline, isoxazole, oxadiazole, where the optional substitution is represented by C.sub.1-6 -alkyl or phenyl, provided that when cyano is the only substituent in R.sup.2, R.sup.2 must contain at least four carbon atoms, and pharmaceutically acceptable acid addition salts thereof.The compounds are useful in the treatment of mental disorders in which a dopaminergic deficit is implicated.
