The invention provides compounds of the general formula (I)
wherein
Ar represents a phenyl group optionally substituted by one or more substituents selected from halogen atoms, or the groups C1-6alkyl, C1-6alkoxy, nitro, -(CH2)qR [where R is hydroxy, -NR3R4 (where R3 and R4 each represent a hydrogen atom or a C1-4 alkyl group, or -NR3R4 forms a saturated heterocyclic amino group which has 5-7 ring members and optionally contains in the ring one or more atoms selected from -O-or -S-or a group -NH-or -N-(CH3)-), -NR5COR6 (where R5 represents a hydrogen atom or a C1-4 alkyl group, and R6 represents a hydrogen atom or a C1-4 alkyl, C1-4 alkoxy, phenyl or -NR3R4 group), -NR5SO2R7 (where R' represents a C1-4 alkyl, phenyl or -NR3R4 group), -COR8 (where R8 represents hydroxy, C 1-4 alkoxy or -NR3R4), -SR9 (where R' is a hydrogen atom, or a C1-4 alkyl or phenyl group), -SOR9, -SO2R9 or -CN, and q represents an integer from 0 to 3], -(CH2) rR'° (where R10 is a C1-4 alkoxy group and r represents an integer from 1 to 3) or -O(CH2)tR11 (where R" represents a hydroxy or C1-4 alkoxy group and t is an integer 2 or 3), or Ar is a phenyl ring substituted by an alkylenedioxy group of formula -O(CH2)pO-where p represents an integer 1 or 2;
Q represents a group of formula
where Ra represents a hydrogen atom or a C1-3 alkyl group, Rb represents
and Rc represents
where R represents a straight or branched C2.3 alkylene chain; R' and R2 each represent a hydrogen atom or a C1-3 alkyl group with the proviso that the sum total of carbon atoms in R' and R2 is not more than 4;
X represents a C1-7 alkylene, C2-7 alkenylene or C2.7alkynylene chain; and
Y represents a bond or a C1-6 alkylene, C2.6 alkenylene or C26 alkynylene chain with the proviso that the sum total of carbon atoms in X and Y is 2-10, and when X represents C 1-7 alkylene and Y represents a bond or C1- 6alkylene, then the group Ar does not represent an unsubstituted phenyl group or a phenyl group substituted by one or two substituents selected solely from halogen atoms or C1-3 alkyl or C1-3 alkoxy groups or an alkylenedioxy group -O(CH2)pO-;
and physiologically acceptable salts and solvates e.g. hydrates thereof.
The compounds have a selective stimulant action at β2-adrenoreceptors and may be used, inter alia, in the treatment of diseases associated with reversible airways obstruction such as asthma and chronic bronchitis.
