Abstract

Hydroxylamine-containing analogues of putrescine and cadaverine have been found effective in inhibiting the mouse liver ornithine decarboxylase, the best among synthesized were 1-aminooxy-3-aminopropane (I50 2.10(-8) M) and 1-aminooxy-4-aminobutane (I50 2.10(-7) M). The inhibitory effect of these substances on the mouse liver ornithine-transaminase and S-adenosylmethionine decarboxylase from E. coli was displayed at concentrations higher by several orders of magnitude, that demonstrated the specificity of the compounds of this type. 1-Aminooxy-3-aminopropane in experiments in vivo suppressed the ornithine decarboxylase activity in mouse liver at 16 mg/kg by 75%, the toxic effect being insignificant.
