title: Cyclic guanidines as dual 5-HT5A/5-HT7 receptor ligands: structure-activity relationship elucidation.
abstract: The optimisation of affinity and selectivity in a novel series of dual 5-HT5A/5-HT7 receptor ligands is described. Brain penetrant 2-aminodihydroquinazolines with low nanomolar affinities were identified.
