Effects of an ACTH short chain neuropeptide in man
Abstract
The authors studied the effect of an ACTH 4-9 analogue (the shortest behaviorally active fragment of the ACTH neuropeptide) on mood in normal aging volunteers. These mood changes, described as a sense of well-being, energy, and drive, are consistent with an arousal-stimulant mechanism of action of the compound. No effect of the compound was found on attention or memory. Because of its apparent safety and the lack of adverse effects, the authors suggest that this short chain neuropeptide be further explored in older individuals for its mood- elevating and potential antidepressant properties.
