The invention relates to use of compounds of formula (I)
wherein
n is 1, 2 or 3;
m is 0, 1, 2 or 3;
any one of A', A2 and A3 is nitrogen and the other two are CH; R' groups are independently selected from those specified in (a) and (b) below, namely:
(a) cyano, hydroxy, groups of formula -S(O)xRa in which x is 0, 1 or 2 and Ra is a C1-4 alkyl group and groups of formula -ORb in which Rb is allyl or a C1-4 alkyl group, which alkyl group is optionally substituted by one or more radicals selected from halo, C1-4 alkoxy and groups of formula -S(O)xRa in which x and Ra are as defined above; (b) C1-4 alkanoyl, C1-4 alkanoylamino, 2-methyl-1,3-dioxalan-2-yl, sulphamoyl, N-C1-4 alkylsulphamoyl, N, N-di-C1-4 alkylsulphamoyl, C1-4 alkylsulphonyloxy, C1-4 alkylsulphonylamino, aminosulphonyloxy, N-C1-4 alkylaminosulphonyloxy, N,N-di-C1-4 alkylaminosulphonyloxy, ureido, 3-C1-4 alkylureido, 3,3-di-C1-4 alkylureido, aminosulphonylamino, (C1-4 alkylaminosulphonyl)amino, (di-C1-4 alkylaminosulphonyl)-animo, carboxy, carboxylic derivatives (selected from carbamoyl, N-C1-4 alkylcarbamoyl, N, N-di-C1-4 alkylcarbamoyl, carboxylic acid halides, C1-4 alkoxycarbonyl, hydroxy-C1-4 alkoxycarbonyl and hydroxymethylene) and groups of formula -ORc in which Re is a straight or branched aliphatic moiety having 1 to 4 carbon atoms, optionally substituted by one or more radicals independently selected from halo, C1-4 alkoxy and groups of formula -S(O)xRa in which x and Ra are as defined above, provided that R° is not a group as defined for Rb above;
R2 is selected from hydrogen, halo, amino, hydroxy, C1-4 alkyl and C1-4 alkoxy;
R3 groups are independently selected from halo, carboxy, amino, C1-4 alkylamino hydroxy, C1-4 alkoxy, hydroxy-C1-4 alkoxy, C1-4 alkylthio and C1-4 alkylsulphonyloxy;
provided that when R2 is hydrogen and either m is 0 or m is 1 and R3 represents halo, then at least one R' group must be selected from (b) above;
and physiologically acceptable salts and/or N-oxides thereof, as inotropic agents, and to pharmaceutical formulations containing them.
The invention also includes compounds of formula (I) (including physiologically acceptable salts and/or their N-oxides) perse, with the proviso that when n and m are both 1, and R2 is H, then when A' is nitrogen, A2 and A3 are both CH and R' is a 4-methoxy group, R3 is nota 7-methoxy group, and when A3 is nitrogen and A' and A2 are both CH and R' is a 4-methylsulphonyl group, R3 is not a 6-methoxy group, and processes for their preparation.
