acth 4 10 peptide Affordable Options,ACTH (4-10), human

The ACTH 4-10 peptide is a fascinating and extensively studied fragment of the adrenocorticotropic hormone (ACTH). While the full ACTH molecule plays a crucial role in the hypothalamic-pituitary-adrenal axis and the body's response to stress, the ACTH (4-10) fragment possesses unique properties that have garnered significant scientific interest. This article will explore the nature of the ACTH 4-10 peptide, its known effects, and its relationship with compounds like Semax, a notable ACTH(4-10) analogue with nootropic properties.

What is the ACTH 4-10 Peptide?

The ACTH 4-10 peptide is a specific sequence of amino acids derived from the larger adrenocorticotropic hormone. Its sequence is typically Met-Glu-His-Phe-Arg-Trp-Gly, giving it a molecular weight of approximately 962.1 g/mol. This peptide is also known by its CAS Number [4037-01-8] and is often referred to as ACTH (4-10), human. Unlike the full ACTH hormone, the ACTH (4-10) fragment is understood to have a reduced endocrine activity, meaning it doesn't significantly stimulate the adrenal cortex in the same way. Instead, its primary areas of impact are believed to be within the central nervous system and in modulating cognitive functions.

Key Properties and Effects of ACTH 4-10

Research into the ACTH 4-10 peptide has revealed several intriguing effects:

* Modulation of Attention: Early studies have demonstrated that the ACTH 4-10 fragment can be a potent modulator of attention in humans. This suggests a role in enhancing focus and concentration.

* Impact on Body Weight: Interestingly, the application of ACTH 4-10 has been observed to reduced body weight in humans by enhancing energy expenditure and suppressing appetite. However, it's noted that this effect might not be present in overweight individuals.

* Neuroendocrine Research: The ACTH (4-10) peptide is a biologically active peptide fragment used extensively in neuroendocrine research to study pituitary gland functions and stress responses.

* Melanocortin Receptor Agonism: The ACTH (4-10) is a melanocortin peptide fragment derived from adrenocorticotropic hormone. It acts as a melanocortin 4 (MC4R) receptor agonist, primarily targeting these receptors, which are involved in various physiological processes.

* Cardiovascular Activity: Research has indicated that a peptide sequence analogous to ACTH-(4-10), specifically gamma-melanocyte-stimulating hormone (gamma-MSH), possesses significantly greater cardiovascular activity, with possesses greater than 100-fold more cardiovascular activity compared to ACTH-(4-10) itself.

Semax: A Prominent ACTH 4-10 Analogue

A significant area of research surrounding the ACTH 4-10 peptide involves its analogues, most notably Semax. Semax is a synthetic ACTH(4-10) analogue with nootropic properties. It is often described as a Semax: ACTH(4-10) analog heptapeptide. Semax is understood to be based on the adrenocorticotropic hormone (ACTH), specifically incorporating an ACTH(4-7) fragment, with the addition of a tripeptide, Pro-Gly-Pro (PGP), to stabilize its C-terminus. This structure, the ACTH (4–7) PGP peptide, contributes to its unique pharmacological profile.

Semax has demonstrated several notable effects:

* Nootropic and Neuroprotective Activities: Semax exerts marked nootropic and neuroprotective activities. This means it can potentially enhance cognitive functions like learning and memory, while also offering protection to brain cells. Studies have investigated its effects on learning processes and its marked neuroprotective activities on cognitive brain functions.

* Brain System Activation: Semax has been shown to activate dopaminergic and serotoninergic brain systems in rodents, suggesting a mechanism for its cognitive-enhancing effects.

* Intracellular Effects: Research has explored the effects of Semax on spontaneous fluctuations of intracellular calcium ion concentration ([Ca2+]i) in pyramidal neurons, indicating its influence on neuronal signaling.

* Degradation Studies: The degradation of Semax in biological systems, such as in serum and in the presence of plasma membranes of rat brain, has been a subject of study to understand its pharmacokinetic profile. This involves analyzing physiologically active peptide concentrations in biological tissues.
