Claims
- 1. A spasmolytically active tertiary amine derivative, acid addition salts and prodrugs thereof of the formula: ##STR18## wherein .circle.A is a phenyl nucleus;
- R.sub.1 and R.sub.2 may be equal or different and are hydrogen, alkyl having 1-3 carbon atoms, hydroxylalkyl or mercaptoalkyl having 1-3 carbon atoms which may be etherified or esterified, alkoxy having 1-3 carbon atoms, the group S(O).sub.m --R.sub.9, wherein R.sub.9 is an alkyl group having 1-3 carbon atoms, and m has the value 0, 1 or 2, a group - NR.sub.10 R.sub.11, wherein R.sub.10 and R.sub.11 represent alkyl having 1-3 carbon atoms, or together may form a saturated, 5 or 6 membered ring optionally containing a member selected from the group consisting of sulphur, oxygen and nitrogen; hydroxy group, mercapto group or amino group, which groups may be derived with an easily removable ester group or ether group; or a halogen atom, or R.sub.1 and R.sub.2 together may form a 5- or 6-membered saturated ring optionally containing 1 or 2 members selected from the group consisting of oxygen, nitrogen and sulphur atoms, which ring is condensed with the phenyl nucleus and may by substituted with one or more alkyl groups having 1- 3 carbon atoms, optionally etherified or esterified hydroxyalkyl having 1-3 carbon atoms or with an oxygen atom;
- R.sub.1 is a hydrogen atom or, together with R.sub.4, may form a ring consisting of 6 or 7 carbon atoms;
- at least one of R.sub.1, R.sub.2 and R.sub.3 being other than hydrogen;
- R.sub.4 is a hydrogen atom or alkyl group having 1-3 carbon atoms;
- R.sub.5 is a straight, branched or cyclic alkyl group having 1-4 carbon atoms;
- R.sub.6 is a straight or branched, saturated or unsaturated alkylene group having a chain length of 3-6 carbon atoms;
- X is a carbonyl group, thiocarbonyl group or SO.sub.2 group;
- R.sub.7 and R.sub.8, together with the nitrogen atom to which they are bound, constitute a fully or partly saturated heterocyclic ring consisting of 5-8 ring atoms optionally containing an oxygen, nitrogen or sulfur atom as the second hetero atom, and optionally containing at least one member selected from the group [consisting of members selected from the group] consisting of 1 to 2 alkyl groups having 1-3 carbon atoms, an alkylene bridge of 2 or 3 carbon atoms across the ring; or oxygen, provided that when the substituent is oxygen having a keto function it has the form of a ketal or oxim, or the ring formed by the R.sub.7 and R.sub.8 may be substituted directly or via an alkylene chain of 1-3 carbon atoms, with 1 or 2 members selected from the group consisting of phenyl, optionally containing halogen; alkyl or alkoxy having 1-3 carbon atoms, hydroxy, amino, mono- or dialkylamino having 1-3 carbon atoms in the alkyl group(s), alkanoyl or thioalkanoyl having 1-3 carbon atoms, hydroxy alkanoyl having 1-3 carbon atoms, benzoyl, optionally esterified or etherified hydroxy or mercapto, optionally mono- or dialkyl or -acyl substituted amino, carbalkoxy having 1-3 carbon atoms in the alkoxy group, a carbamoyl, thio carbamoyl, sulfamoyl or carbamoyloxy group of which the nitrogen atom may be substituted by 1 or 2 alkoxy groups having 1-3 carbon atoms or alkyl groups having 1-5 carbon atoms, which, via a nitrogen, oxygen or sulphur atom, may form a saturated heterocyclic group consisting of 5 or 6 ring atoms.
- 2. Compounds as claimed in claim 1 of the formula (1) wherein .circle.A is the phenyl group, R.sub.1 is the p-methoxy group, R.sub.2 and R.sub.3 are hydrogen, R.sub.4 is the methyl group, R.sub.5 is the ethyl group, and X is the carbonyl group, the group -NR.sub.7 R.sub.8 has one of the following meanings: ##STR19## and the carbon atoms to which R.sub.4 is bound and acid addition salts and prodrugs thereof.
- 3. Spasmolytically active compositions, characterized in that they comprise at least one compound of claim 1 as the active component in form suitable for administration.
