There are disclosed compounds of the general formula
The heteroatom X is preferably oxygen, but may have other values. The group W is preferably a carbonyl group, but may have other values. The preferred heterocyclic ring is thus a 4-oxo-4H-1-benzopyran ring. This may have a wide range of R₂, R₃, R₆ and R₇ substituents. Y is a linking group, chosen from a wide range, but including -COO- , -CONH- , -O- , -SO₂- and -SO₂NH-. Z is an alkylene chain, and B is a complex amine. These compounds and their prodrugs, enantiomers, diastereoisomers, N-oxides and pharmaceutically acceptable salts are useful for the treatment of hypertension and urinary tract troubles associated with benign prostatic hypertrophy, and for the treatment of other diseases.
(X = -CO-, -COO-, -CONH-, -CON(CH 3 )-, -CH 2 NH-, -CH 2 N(CH 3 )-, -CH 2 NHCO-, -CH 2 N(CH 3 )CO-, -CH 2 0-, -CH 2 S-, -CH 2 SO-, or -CH 2 SO 2 -, n=1 to 4, B = a complex amine) and their enantiomers, diastereoisomers, N-oxides and pharmaceutically acceptable salts are useful as long lasting antispasmodic drugs, particularly for the treatment of disturbances of the lower urinary tract.
