title: Ether derivatives of 3-piperidinopropan-1-ol as non-imidazole histamine H3 receptor antagonists.
abstract: A series of aliphatic and aromatic ether derivatives of 3-piperidinopropan-1-ol has been prepared by four different methods. The ethers obtained were evaluated for their affinities at recombinant human histamine H3 receptor, stably expressed in CHO-K1 or HEK 293 cells. All compounds investigated show from moderate to high in vitro affinities in the nanomolar concentration range. Selected compounds were investigated under in vivo conditions after oral administration to mice. Some proved to be highly potent and orally available histamine H3 receptor antagonists. The most potent antagonists in this series have been in vitro the 4-(1,1-dimethylpropyl)phenyl ether 19 (hH3R K(i) = 8.4 nM) and in vivo the simple ethyl ether 2 (ED50 = 1.0mg/kg).
