摘要:
A series of compounds possessing both H, histamine receptor antagonist and 5-lipoxygenase (5-LO) inhibitory activities was synthesized. The H-1-binding scaffolds of cetirizine, efletirizine, and loratadine were linked to a lipophilic N-hydroxyurea, the 5-LO inhibiting moiety of zileuton. Both activities were observed in vivo, as was increased CYP3A4 inhibition compared to their respective single-function drugs. Selected analogs in the series were shown to be orally active in guinea pig models. (C) 2004 Elsevier Ltd. All rights reserved.
