title: Diamine derivatives containing imidazolidinylidene propanedinitrile as a new class of histamine H3 receptor antagonists. Part I.
abstract: Novel diamine derivatives containing imidazolidinylidene propanedinitrile were synthesized and evaluated for histamine H(3) receptor-binding affinities. High-affinity ligands 3d, 3k, and 3n showed potent H(3) receptor antagonism and excellent selectivity over human H(1), H(2) and H(4) receptors.
