title: Piperidine-containing histamine H3 receptor antagonists of the carbamate series: the influence of the additional ether functionality.
abstract: Recently novel leads for histamine H3 receptor antagonists of the non-imidazole type have been described. As a continuation of this research eleven new carbamate derivatives possessing an additional ether functionality were prepared. The compounds were evaluated in vitro for their antagonist activity on isolated organs of guinea-pig (GP) H3 as well as H2, H1, and M3 receptors, respectively. All compounds investigated possessed moderate antagonist affinities at guinea-pig histamine H3 receptors (pA2 6.11-6.76). An ether functionality introduced in different places of the lipophilic part of carbamates differently influenced activity and selectivity toward H3, M3, and other histamine receptors tested.
