What is ACTH (1-17) and its primary function?

ACTH (1-17) is a synthetic peptide composed of 17 amino acids, and its chemical formula is C75H106N20O19S. It is a sub-segment of the adrenocorticotropic hormone (ACTH), which is a pivotal component in the endocrine system primarily known for its role in stimulating the adrenal glands to release cortisol, a key stress hormone. The truncated version, ACTH (1-17), retains the active core sequence of the full ACTH hormone, enabling it to engage effectively with the melanocortin receptors, particularly the MC2R found in the adrenal cortex. This interaction allows it to imitate the regulatory functions of natural ACTH, triggering a cascade of intracellular responses that facilitate steroidogenesis. Cortisol, the resultant hormone from this stimulation, is essential for numerous physiological processes, including immune response modulation, metabolism regulation, and maintenance of homeostasis in response to stress. ACTH (1-17) is also involved in the regulation of the hypothalamic-pituitary-adrenal (HPA) axis, critical for maintaining balance and responding adaptively to the body’s needs. Clinically, its implications extend to therapeutic potentials, especially in circumstances characterized by deficient ACTH activity or adrenal insufficiency. Beyond its hormonal activity, research suggests that ACTH (1-17) could have neuroprotective effects, given its participation in neuroendocrine signaling pathways and influence on various neural circuits. Whilst its therapeutic dominance is still under exploration, these peptide sequences illuminate a pathway to innovative treatments for a spectrum of disorders related to cortisol imbalance and stress-related illnesses, making them a promising candidate for ongoing biotechnological advancements.
