There is provided compounds of formula (I), wherein R1a, R1b, n, Y1, Y2, Y3, Y4, Z1, Z2, R2 and R3 have meanings given in the description, and pharmaceutically-acceptable salts thereof, which compounds are useful as selective agonists of the AT2 receptor, and thus, in particular, in the treatment of inter alia gastrointestinal conditions, such as dyspepsia, IBS and MOF, and cardiovascular disorders.
selective angiotensin II AT(2) receptor agonist (1) has been developed. In analogy with the transformation of losartan to valsartan it was demonstrated that a non-cyclic moiety could be employed as an imidazole replacement to obtain AT(2) selective compounds. In all the three series, AT(2) receptor ligands with affinities in the lower nanomolar range were found. None of the analogues exhibited any affinity
