Structural alterations in the 2- and 5-positions of the first drug-like selective angiotensin II AT 2 receptor agonist (1) have been performed. The imidazole ring system was proven to be a strong determinant for the AT 2 selectivity, and with few exceptions all variations gave good AT 2 receptor affinities and with retained high AT 2 /AT 1 selectivities. On the contrary to the findings with AT 1 receptor agonists, the impact of structural modifications in the 5-position of the AT 2 selective compounds were less pronounced regarding activation of the AT 2 receptor. The butyloxyphenyl (56) and the propylthienyl (50) derivatives were found to exert a high agonistic effect as deduced from their capacity to induce neurite elongation in neuronal cells, as does angiotensin II.
