Histamine was converted to a selective histamine H3-receptor antagonist by capping the primary amine with 2-naphthalenesulfonyl chloride. Higher receptor affinity and lower variability in the data from the various bioassays were achieved with the 2-naphthalensulfonamides of histamine homologues.

The influence of alkyl chain length variation on the histamine H3 receptor activity of histamine homologs 1 was investigated.A series of 4(5)-(ω-aminoalkyl)-1H-imidazoles 1 was prepared with an alkyl chain length varying from one methylene group to 10 methylene groups.Besides the H3 activity, the affinities of these compounds for the H1 and H2 receptors were determined.The ethylene chain of histamine is optimal for agonistic activity on all three histamine receptor subtypes.For the H3 receptor, elongation of the alkyl chain from three methylene groups on leads to compounds with antagonistic properties. 4(5)-(5-Aminopentyl)-1H-imidazole (impentamine, 1e) is the most potent and selective H3 antagonist from this series of 4(5)-(ω-aminoalkyl)-1H-imidazoles 1, with a pA2 value of 8.4 (on guinea pig jejunum).A specific antagonistic binding site for this compound is proposed.

A general method has been developed for the synthesis of 1H-imidazoles containing a phosphoryl group in positions 2 or 4(5) based on lithium intermediates. The possibility of further functionalization of the ring using electrophiles has also been demonstrated.
4-(2-Methyl-5,6,7,8-tetrahydro-quinolin-7-ylmethyl)-1,3-dihydro-imidazole-2-thione as specific alpha2B agonist and methods of using the same

, (2008/06/13)
The compound of the formula wherein the * indicates an asymmetric carbon, is specific to alpha2B adrenergic receptors in preference over alpha2A and alpha2C adrenergic receptors, and as such has no or only minimal cardivascular and/or sedatory activity. The compound is useful as medicament in mammals, including humans, for treatment of diseases and or alleviations of conditions which are responsive to treatment by agonists of alpha2B adrenergic receptors.
