Claims
- 1. A compound of the formula I ##STR70## in which X represents --O--, --CH.sub.2 --, --S--, or --NH--,
- n represents 1 or 2,
- m represents 2, 3 or 4, and
- A represents ##STR71## in which R.sup.3 and R.sup.4, which may be the same or different, each represents
- a hydrogen atom;
- a straight or branched chain alkyl group having from 1 to 10 carbon atoms or
- an alkenyl group having from 2 to 10 carbon atoms, wherein said alkyl or alkenyl group is unsubstituted or substituted by one or more groups, which may be the same or different, selected from the group consisting of hydroxyl groups; --OR.sup.6 groups in which R.sup.6 represents a lower alkyl group or a phenyl group; --NR.sup.7 R.sup.8 groups in which R.sup.7 and R.sup.8 each denotes a hydrogen atom, a lower alkyl group, a phenyl group, or a lower acyl group; --COOR.sup.9 groups, in which R.sup.9 represents a hydrogen atom or a lower alkyl group; --CONR.sup.7 R.sup.8 in which R.sup.7 and R.sup.8 are as defined above and in addition together with the N atom may form a 5 or 6 membered ring; phenyl groups which are unsubstituted or substituted by a lower alkyl, lower alkoxy, phenoxy, halogen, dimethylaminomethyl, trifluoromethyl, nitro, cyano, sulphonic acid or sulphonamide substituent; heterocyclic groups selected from the group consisting of pyridine, thiophen and furan groups, which are unsubstituted or substituted as defined above for said phenyl groups, lower alkylsulphonyl and phenylsulphonyl groups, and nitrile groups;
- a phenyl group or a phenyl group bearing one or more substituents selected from the group consisting of (C.sub.1 -C.sub.4) lower alkyl, (C.sub.1 -C.sub.4) lower alkoxy, phenoxy, chlorine, bromine, iodine, fluorine, dimethylaminomethyl, trifluoromethyl, nitro, cyano, sulphonic acid and sulphonamide substituents; or
- a five or six membered heterocycle selected from the group consisting of pyridine, thiophen, furan and tetrahydrofuran; or
- R.sup.3 and R.sup.4 together with the carbon atom to which they are bonded form a cyclohexyl or cyclopentyl ring;
- or a physiologically tolerable salt thereof.
- 2. A compound of Formula I as claimed in claim 1 wherein
- A represents ##STR72## R.sup.3 being hydrogen and R.sup.4 being straight or branched chain alkyl having from 1 to 6 carbon atoms.
- 3. A compound of the formula I as claimed in claim 1, wherein said alkyl or alkenyl group has up to 6 carbon atoms.
- 4. A physiologically tolerable salt of a compound of the formula I as claimed in claim 1.
- 5. A pharmaceutical preparation which comprises, as active ingredient, a compound of the formula I as claimed in claim 1 or a physiologically tolerable salt thereof, in admixture or conjunction with a pharmaceutically suitable carrier.
- 6. A pharmaceutical preparation as claimed in claim 5, containing from 0.01 to 10 mg of the active ingredient per kg body weight.
- 7. Method for the treatment of pathological conditions resulting from hypersecretion of gastric acid by administering to the patient an effective amount of a compound of formula I as claimed in claim 1.
