Inhibition of Ornithine Decarboxylase Activity in Mouse Kidney by Administration of Diamines.

Abstract
On testosterone administration the hypertrophied kidneys of castrated mice exhibited a striking increase in the activity of ornithine decarboxylase (EC 4.1.1.17) and an accumulation of polyamines. The effect on ornithine decarboxylase activity could be inhibited by injections of putrescine or its homologues, 1,3-diaminopropane and 1,5-diaminopentane (cadaverine). Most effective was 1,3-diaminopropane which also restrained the accumulation of polyamines.
