Abstract
The invention provides a series of novel heterocyclic amides of the formula I in which the group A; CRa can be --CRb.dbd.CRa--, --CHRb--CHRa-- or --N.dbd.CRa--, the amidic group Re.L can be Rd.X.CO.NH, Re.X.CS.NH or Re.NH.CO attached to position 4, 5 or 6 of the benzenoid moiety, z is an acid group selected from the group consisting of carboxy, an acylsulphonamide residue of the formula CO.NH.SO.sub.n Rg and a tetrazolyl residue of the formula II and the radicals Ra, Rb, Rc, Rd, Re, Rf, Rg, Rh, n, X, G.sup.1,Q and G.sup.2 have the meanings defined in the following specification. The compounds of formula I are leukotriene antagonists. The invention also provides pharmaceutically acceptable salts of the formula I compounds; pharmaceutical compositions containing the formula I compounds, or their salts, for use in the treatment of, for example, allergic or inflammatory diseases, or endotoxic or traumatic shock conditions; and processes for the manufacture of the formula I compounds, as well as intermediates for use in such manufacture.
