Semax, also known as ACTH(4-10) Pro-Gly-Pro, is a synthetic peptide that has been the subject of extensive research due to its potential neuroprotective and nootropic effects. This heptapeptide, derived from the adrenocorticotropic hormone (ACTH), has been shown to possess a wide range of biological activities, including enhancing memory, learning, and neurogenesis.

Semax is unique in its ability to cross the blood-brain barrier and exert its effects directly on the central nervous system. It has been shown to stimulate the release of brain-derived neurotrophic factor (BDNF), a protein that plays a crucial role in the survival of neurons and the growth of new neurons and synapses. Studies by Dolotov et al. (2006) have demonstrated that Semax can enhance memory and learning in rats, suggesting potential applications in cognitive enhancement and the treatment of cognitive disorders.

In addition to its nootropic effects, Semax has been shown to possess neuroprotective properties. Research by Stavchansky et al. (2008) found that Semax could protect neurons from oxidative stress and apoptosis, suggesting potential applications in the treatment of neurodegenerative diseases such as Alzheimer's and Parkinson's disease.

Given its nootropic and neuroprotective effects, Semax has been proposed as a potential therapeutic agent for a variety of conditions, including cognitive disorders, stroke, and optic nerve disease. For instance, a study by Myasoedov et al. (2010) found that Semax could improve outcomes in patients with ischemic stroke, indicating its potential as a therapeutic agent in stroke recovery.

While research on Semax is promising, it is important to note that most studies have been conducted in animals or in vitro. More research is needed to fully understand the potential effects and applications of Semax in humans. However, the existing body of research suggests that Semax could be a promising tool in the treatment of cognitive disorders and neurodegenerative diseases.

Selank, also known as TP-7, is a synthetic peptide that has garnered significant attention in the scientific community due to its potential anxiolytic, neuroprotective, and nootropic effects. This heptapeptide, derived from the naturally occurring human tetrapeptide Tuftsin, has been shown to possess a wide range of biological activities, including enhancing memory, reducing anxiety, and potentially mitigating the effects of neurodegenerative diseases.

Selank's primary mechanism of action involves its interaction with the GABAergic system, the body's main inhibitory neurotransmitter system. By modulating the activity of GABA receptors, Selank can exert a calming effect on the brain, reducing anxiety and enhancing cognitive function. Studies by Semenova et al. (2014) have demonstrated that Selank can enhance memory and learning in rats, suggesting potential applications in cognitive enhancement and the treatment of cognitive disorders.

In addition to its anxiolytic and nootropic effects, Selank has been shown to possess neuroprotective properties. Research by Ershov et al. (2016) found that Selank could protect neurons from oxidative stress, suggesting potential applications in the treatment of neurodegenerative diseases such as Alzheimer's and Parkinson's disease.

Given its anxiolytic, nootropic, and neuroprotective effects, Selank has been proposed as a potential therapeutic agent for a variety of conditions, including anxiety disorders, cognitive disorders, and neurodegenerative diseases. For instance, a study by Medvedev et al. (2017) found that Selank could improve symptoms in patients with generalized anxiety disorder, indicating its potential as a therapeutic agent in the treatment of anxiety disorders.

While research on Selank is promising, it is important to note that most studies have been conducted in animals or in vitro.

Before it was discovered in 2000, there was a hypothesis that a similar type of protein existed that performed many of the functions we see in FGF23. This was originally referred to as phosphatonin. Various effects were described and noted by researchers including inhibition of production and inhibition of secretion of parathyroid hormone. Derived from the bone Fibroblast Growth Factor 23 is a phosphaturic hormone. It increases phosphate excretion when acting on the kidney and also suppresses the biosynthesis of 1,25(OH)2D3.

Mechanism
Despite various research studies into the topic, many of the mechanisms for the regulations of FGF23 production remain a mystery to the scientific community. While we know that mutations in PHEX, ENPP1 and DMP1 result in the increased expression of FGF23, it is unclear why this occurs. This also means that currently, it is not possible to regulate the production of FGF23 either. We also do not know how signals from FGF23 regulate vitamin D metabolism. However, understanding these types of mechanisms could offer information needed to provide better treatment for deranged bone and mineral metabolism.

Interactions
Molecular interactions involving FGF-23, vitamin D and klotho do provide the solution needed to regulate phosphate levels within the body. Furthermore, an interaction between Vitamin D and FGF3 can have an impact on renal phosphate balance. As well as this, when in the presence of klotho, FGF3 does actually increase bioactivity and begins to change systemic phosphate homeostasis.

Function
Based on research it seems that the main function for FGF23 is the regulation of phosphate concentration in plasma. It seems to be secreted from the osteocytes due to elevated levels . When acting upon the kidneys, the hormone reduces the expression of NPT2. This is a sodium-phosphate cotransporter found in the proximal tube.
As such, it appears as though FGF23 is able to reduce the reabsorption, all the while maxing the excretion of phosphate. It has also been suggested that the hormone is able to suppress 1-alpha-hydroxylase. If this is the case, it can limit its potential to activate vitamin D and thus impair the ability for calcium absorption.

Structure
FGF243 is located on the chromosome 12. It is composed of three exons. The crystal structure of FGF23 is completely different from the common conformation typically adopted by paracrine-acting FGFs. Instead, there is a conformation of the HPR region between beta strands 10 and 12. As well as this, there is a cleft between the other HPR-binding region, the beta1-beta12 loop and this one. This comes before a direct interaction between HPR sulfate and FGF23s backbone atoms. Due to this, endocrine function is benefitted and HPR-binding affinity is reduced for the lipangs.
Certain mutations that cause the protein to be completely resistant to proteolytic cleavage does trigger a surge in activity of the protein and the renal phosphate loss typically found in certain human diseases including hypophosphatemic rickets.
Studies have also revealed that FGF23 is overproduced in certain tumors including phosphaturic mesenchymal tumors. Furthermore a reduced level of activity for this protein is believed to lead to higher phosphate levels and familial tumor calcinosis clinical syndrome.

FGF23 HUMAN Protein has a total Mw of 22.5kDa.
