摘要:
A piperazine derivative is disclosed of formula (I): ##STR1## and the non-toxic addition salts thereof, along with a process for preparation, pharmaceutical composition, and method of treating conditions characterized by histamine activity.
摘要:
The process consists of reacting (-)trans-N-p-fluorophenyl)-3-[[3,4-(methylenedioxy)phenoxy]methyl]-piperidine acetate with 2-chloro- or 2-bromo-4'-fluoroacetophenone. The resulting compound can be isolated as a pharmaceutically acceptable addition salt by reaction with the corresponding acid.
摘要:
The invention relates to new N-benzoylmethyl-piperidines of the general formula (I): ##STR1## wherein X is a halogen atom, as well as their pharmaceutically acceptable addition salts. The compounds are potentially useful to treat depressions.
摘要:
Derivatives of piperazine having the general formula ##STR1## wherein R.sub.1 is benzhydryl or cinnamyl and R.sub.2 is selected from the group consisting of ##STR2## --(CH.sub.2).sub.3 --R.sub.8, --CH.sub.2 NHR.sub.9, --CH.sub.2 NH.sub.2 and --COR.sub.10 ; wherein R.sub.3 is hydrogen, chloromethyl, (4-benzhydryl-1-piperazinyl) methyl, 4-morpholinylmethyl or 1-piperidinylmethyl, R.sub.4 is hydrogen, chloromethyl or carbethoxy, R.sub.5 and R.sub.6 taken together are an oxygen atom or the radical --O--(CH.sub.2).sub.2 --O--, R.sub.7 is methyl, phenyl or 2-thienyl, R.sub.8 is 4-morpholinyl, 1-piperidinyl or 4-benzhydryl-1-piperazinyl, R.sub.9 is 2-oxo-1- (pyrrolidinyl) acetyl, 2-hydroxybenzoyl or 4-sulfamoylbenzoyl, R.sub.10 is 2-oxo-1-(pyrrolidinyl)methyl or 4-sulfamoylphenyl and X is oxygen or NH; as well as methods for making the same and their use in a pharmaceutical composition is proposed. The compounds have cardiovascular properties and increasing effects on cerebral flow.
摘要:
The invention relates to new N,N,N'N'-tetra-substituted-1,2-ethanediamine compounds of the general formula (I): ##STR1## wherein X is a carbonyl (CO), hydroxymethylen (CHOH) or p-fluorophenyl-methylen (p--F--C.sub.6 H.sub.4 --CH) group and R is a benzyl group optionally substituted in p-- with an halogen, or R is a 2-pyrimidinyl group with the proviso that simultaneously X may not be p-fluorophenyl-methylen (p--F--C.sub.6 H.sub.4 --CH) and R may not be an unsubstituted benzyl group, as well as their pharmaceutically acceptable additions salts.The compounds are potentially useful in the treatment of sigma receptor-related nervous system diseases.
