摘要:
The invention relates to anxiolytic pharmaceutical compositions comprising as active ingredient 1-sytrylisoquinoline derivatives of general formula (I), whereinn is 1, 2, 3 or 4;R may be the same or different and represent(s) hydrogen, lower alkyl, lower alkoxy or hydroxy, or two substituents R attached to adjacent carbon atoms may form together an alkylenedioxy group;R.sup.1 represents hydrogen or lower alkyl, andAr stands for an optionally substituted aryl or heteroaryl,Some of the compounds of general formula (I) is known, but the majority thereof has not so far described in the literature.The invention also encompasses the preparation of the new compounds of general formula (I), which comprises reacting a compound of general formula (II) with an aldehyde or general formula (III) in the presence of a condensing agent or an acidic catalyst.
摘要:
Novel basic ether of general formula (I), ##STR1## wherein R.sup.1 and R.sup.2 are independently hydrogen, halogen or C.sub.1-4 alkoxy, or together they represent a 3,4-methylenedioxy group,R stands for C.sub.1-8 alkyl,R.sup.3 represents hydrogen, C.sub.1-4 alkyl or hydroxy,A is a valency bond or methylene group,R.sup.4 and R.sup.5 are independently hydrogen, C.sub.1-12 alkyl or C.sub.1-12 alkenyl, orR.sup.4 and R.sup.5 form together with the adjacent nitrogen atom 1-pyrrolidinyl, 1-piperidinyl, morpholino or 1-piperazinyl groups, stereo and optically active isomers and their possible mixtures, acid-addition salts and quaternary ammonium derivatives thereof. The basic ethers have antiulceric and anxiolytic activities.
