title: Adrenal-mediated endogenous metabolites inhibit puberty in female mice.
abstract: While assessing a potential role of adrenal glands in the production of the hitherto unidentified puberty-delaying pheromone of female mice, the urinary volatile profiles of normal and adrenalectomized animals were quantitatively compared. Six components, whose concentrations were depressed after adrenalectomy, were identified: 2-heptanone, trans-5-hepten-2-one, trans-4-hepten-2-one, n-pentyl acetate, cis-2-penten-1-yl acetate, and 2,5-dimethylpyrazine. When these laboratory-synthesized chemicals were added (in their natural concentrations) to either previously inactive urine from adrenalectomized females or plain water, the biological activity was fully restored.
