In the presence of molecular oxygen and a catalytic amount of copper(II) ion, ascorbate almost completely degraded histamine (approx. 72%). The reaction was shown to occur at the imidazole group but not at the primary amino group in histamine. 4-[2-(Acetylamino)ethyl]-2,3-dihydroimidazol-2-one...

Properties of N-acetylhistamine deacetylase in rat brain were studied, utilizing a sensitive coupled radioenzymatic assay. The Km for N-acetylhistamine for this deacetylase was 660 microM and its Vmax was 330 pmol/h/mg protein. N-Acetylhistamine deacetylase activity increased 80% in the presence...

Oscillographic polarography in an alkaline medium has shown that the alkaloid N-isovalerylhistamine appears as an expressive wave of the adsorption character in the cathode portion of the curve. This makes it possible to detect it at concentrations up to 10(-6)...

The purpose of this study was to examine the effects of intracerebroventricular (i.c.v.) administration of N-acetylhistamine on rectal temperature, histamine level, histidine decarboxylase (HDC) activity, and the turnover rate of monoamines in mice. More than 60 micrograms of N-acetylhistamine induced...
