In an extension of very recently published studies on successful imidazole replacements in some series of histamine H(3) receptor antagonists, we report on a new class of lipophilic nonimidazole antagonist having an aliphatic tertiary amino moiety connected to a benzyl
A method for the simultaneous determinations of histamine and its metabolite N tau-methylhistamine by HPLC-chemiluminescence coupled with immobilized diamine oxidase was developed. The method was based on the determination of chemiluminescence formed by the reaction of a luminol-ferricyanide mixture in
