From histamine to imidazolylalkyl-sulfonamides: the design of a novel series of histamine H3-receptor antagonists

Bioorg Med Chem Lett. 1999 Jul 5;9(13):1825-30. doi: 10.1016/s0960-894x(99)00272-3.

Abstract

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.
