Urinary metabolites of polyamines in rats.
Urinary metabolites of polyamines in rats were studied systematically by the intraperitoneal injection of radioactive polyamines. Urinary metabolites were fractionated into 4 fractions containing non-polar and acidic compounds, acidic and neutral ampholytes, basic ampholytes and polyamines. A large amount of radioactivity was detected in the fractions containing non-polar and acidic compounds and polyamines of urine of rats injected with radioactive putrescine, while in the case of the injection of radioactive spermidine or spermine a relatively large amount of radioactivity was found in the basic ampholyte fraction as well as in the polyamine fraction. Analysis of these fractions indicated that gamma-aminobutyric acid, N-monoacetylputrescine, 2(3)-hydroxyputrescine, putreanine, N-(3-aminopropyl)-4-aminobutyric acid (isoputreanine), spermic acid, N-(3-aminopropyl), N'-(2-carboxyethyl)-1,4-diaminobutane, and N-monoacetylspermidine A and B were excreted as urinary metabolites of the polyamines in addition to putrescine, spermidine and spermine.
