Piperidinoalkyl-, morpholinoalkyl- or [(pyrid-2-yl)methylthio]alkyl-substituents were introduced into position 2 of the essential histamine structure. These 2-substituted histamine derivatives were prepared via reaction of imidate hydrochlorides in liquid ammonia under pressure with 1,3-dihydroxypropanone followed by a stepwise build-up of the side chain in position 4 of the imidazole nucleus (route I) or by cyclization with 2-oxo-4-phthalimido-1-butyl acetate (route II) followed by deprotection of the primary amine function. The novel compounds were screened for H1-activity on the isolated guinea-pig ileum and for H2-activity on the isolated guinea-pig right atrium. While 10a, c-e proved to be weak partial H1-agonists, 10b, f were very weak H1-antagonists.
