摘要:
The present invention relates to .alpha.,.beta.-dimethylhistamine, of the rmula: ##STR1## in racemic form, or an optical isomer form or mixture of diastereoisomers and its acid addition salts. It may be prepared from an alkyl 2-amino 3-(1H-imidazol-4-yl)-carboxylate.
摘要:
The invention relates to a pharmaceutical composition containing histamine derivatives and to a method for treating diseases which involve histamine release and synthesis in the human or animal body.
摘要:
Agonist compounds of the histamine H.sub.3 receptor for therapeutic use, pharmaceutical compositions acting as agonists of the said receptor and preparation process are disclosed.The compounds are derived from an amine R-NH.sub.2 having a high affinity for the histamine H.sub.3 receptor and to the primary amine function of which a group which gives rise to a bond that is capable of being slowly hydrolyzed in a neutral medium is attached. The pharmaceutical compositions contain these compounds and a pharmaceutically acceptable vehicle or excipient.These compounds are used for producing a medicinal product which inhibits the synthesis and the release of histamine, in particular, possessing sedative, sleep-regulating, anticonvulsant, antidepressant, anti-allergic, anti-inflammatory, antisecretory or anti-ulcerous effects.
摘要:
A compound selected from the group consisting of a compound of the formula wherein the substituents are defined as in the specification having antagonist properties to histamine H3-receptors.
摘要:
