The effect of short-term intragastric arterial infusion of pentagastrin and methacholine on histamine and N tau-methyl histamine secretory rates was evaluated in mongrel dogs in vivo. Doses of pentagastrin and methacholine were chosen that stimulate gastric acid secretion equivalently. Histamine
Rapid and highly sensitive high-performance liquid chromatographic method for the determination of histamine and 3-methylhistamine in biological samples using fluorescamine as the derivatizing agent.

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

In order to trace the loss of N tau-methylhistamine, a principal metabolite of histamine, during extraction and purification from human plasma and urine samples, N tau-[3H]methylhistamine was prepared in two steps from N alpha t-butoxycarbonylhistamine (II). In the first step
Novel substituted N-phenylcarbamates as derivatives of 3-(1 H-imidazol-4-yl)propanol were prepared and tested for their antagonist potency in vitro and in vivo at histamine H3 receptors. Structural modifications with different alkyl and acetyl moieties were performed in an attempt to optimize
