previously utilised in our laboratory for the preparation of the acyclic aryl-guanidine counterparts. Compounds 8b and 18c showed the highest affinity and antagonistic activity, within their series, towards the α2-adrenoceptor in human brain tissue in vitro experiments. Structure-activity relationships have been established for the design and biological evaluation of novel α2-adrenoceptor ligands.
