Semax is one of those subjects where the details matter more than the headlines. This page pulls together the background, the mechanisms, and the practical points readers ask about most.
Updated 2026-06-08. Numbers and descriptions here follow the published literature rather than marketing material.
Development took place during the 1980s at institutes of the Russian Academy of Sciences, where peptide fragments of ACTH were screened for cognitive and neuroprotective effects. The compound received regulatory approval in Russia as a nasal preparation, marketed for conditions such as ischemic stroke, transient ischemic attacks, and optic nerve disorders. Registration in other countries has not followed. Most published clinical reports originate from a small number of Russian research groups, and independent replication outside that setting remains limited. The regulatory status therefore differs sharply between Russia and the rest of the world.
Laboratory work points toward modulation of neurotrophic signaling, particularly expression of brain-derived neurotrophic factor and nerve growth factor in hippocampal tissue. Studies also describe effects on monoamine turnover, inflammatory mediators, and oxidative markers. These observations come mainly from animal models and cultured cells, so the causal chain in humans is not firmly established. Whether the reported molecular changes translate into measurable clinical benefit is an open question. Reviews generally present the mechanism as plausible rather than demonstrated.
Clinical evidence consists largely of small trials with modest sample sizes, often without independent replication. Reported endpoints include cognitive scores, recovery after stroke, and visual function, but study designs vary widely and few trials meet contemporary reporting standards. Systematic reviewers have noted a high risk of bias in several of these reports. No large multicenter trial conducted outside Russia has been published. The compound is therefore best described as investigational in most jurisdictions, with its clinical role still unresolved.
Development of the compound took place in the Soviet Union during the 1980s, largely through peptide research groups affiliated with the Shemyakin-Ovchinnikov Institute and Moscow State University. Investigators screened fragments of adrenocorticotropic hormone for activity on the central nervous system while attempting to separate cognitive effects from hormonal ones. The shortened sequence was selected because it retained behavioral activity in animal models without stimulating corticosteroid release. Early publications described the molecule as an ACTH(4-10) analog.
Published research on this peptide originates mainly from Russian laboratories, and the wider international literature is comparatively thin. Studies have used rodent models of stroke, hypoxia, and memory tasks, with a smaller number of human trials reported. Reported outcomes include changes in attention and memory measures, along with effects on neurotrophic factor expression in some experiments. Small sample sizes, inconsistent dosing protocols, and limited independent replication are widely noted limitations, so the strength of the clinical evidence remains an open question.

Gay-Lussac's law A chemical law used for each of the two relationships derived by French chemist Joseph Louis Gay-Lussac and which concern the properties of gases, though the name is more usually applied to his law of combining volumes.
. The Michaelis constant KM is experimentally defined as the concentration at which the rate of the enzyme reaction is half Vmax, which can be verified by substituting [S] = KM into the Michaelis–Menten equation and can also be seen graphically. If the rate-determining enzymatic step is slow compared to substrate dissociation (
== Common themes == Architect Richard Buday has contended that architectural works have been used to justify loyalty to an area's rulers, or to religious and spiritual figures. Buday suggests that "the Sphinx and the pyramids were outsized visual demands for respect and obedience to Pharaoh. The Parthenon was constructed for societal manipulation, as well as to honor a goddess (the temple's ornamentation reminded Athenians that their beating back of a Persian invasion was an act of divine intervention). Roman triumphal arches were self-aggrandizing demonstrations of rulers' might and superiority". Later in history, Buday writes that various leaders have invoked particular architectural styles to invoke connections with previous historical states and ideas which are associated with them, such as using ancient Greek and Roman imagery to convey the idea of democracy, or invoking similar classical architecture to denote imperial ambitions. In modern times, architecture is used to attract tourism.
After SELEX, the researcher might mutate or change the chemistry of the aptamers and do another selection, or might use rational design processes to engineer improvements. Non-SELEX methods for discovering aptamers also exist. Researchers optimize aptamers to achieve a variety of beneficial features. The most important feature is specific and sensitive binding to the chosen target. When aptamers are exposed to bodily fluids, as in serum tests or aptamer therapeutics, it is often important for them to resist digestion by DNA- and RNA-destroying enzymes. Therapeutic aptamers often must be modified to clear slowly from the body. Aptamers that change their shape dramatically when they bind their target are useful as molecular switches to turn a sensor on and off. Some aptamers are engineered to fit into a biosensor or in a test of a biological sample. It can be useful in some cases for the aptamer to accomplish a pre-defined level or speed of binding. As the yield of the synthesis used to produce known aptamers shrinks quickly for longer sequences, researchers often truncate aptamers to the minimal binding sequence to reduce the production cost.

== Diagnosis == Craniocervical instability is usually diagnosed through neuro-anatomical measurement using radiography. Digital Motion X-ray is considered the most accurate method. Upright magnetic resonance imaging, supine magnetic resonance imaging, CT scan, and flexion and extension x-rays may also be used but are far less accurate and have a much higher potential for false negatives. The measurements to diagnose craniocervical instability are:
Given its conservation throughout evolution, the action potential seems to confer evolutionary advantages. One function of action potentials is rapid, long-range signaling within the organism; the conduction velocity can exceed 110 m/s, which is one-third the speed of sound. For comparison, a hormone molecule carried in the bloodstream moves at roughly 8 m/s in large arteries. Part of this function is the tight coordination of mechanical events, such as the contraction of the heart. A second function is the computation associated with its generation. Being an all-or-none signal that does not decay with transmission distance, the action potential has similar advantages to digital electronics. The integration of various dendritic signals at the axon hillock and its thresholding to form a complex train of action potentials is another form of computation, one that has been exploited biologically to form central pattern generators and mimicked in artificial neural networks. The common prokaryotic/eukaryotic ancestor, which lived perhaps four billion years ago, is believed to have had voltage-gated channels. This functionality was likely, at some later point, cross-purposed to provide a communication mechanism. Even modern single-celled bacteria can utilize action potentials to communicate with other bacteria in the same biofilm.
Using one of the above definitions, dinosaurs can be generally described as archosaurs with hind limbs held erect beneath the body. Other prehistoric animals, including pterosaurs, mosasaurs, ichthyosaurs, plesiosaurs, and Dimetrodon, while often popularly conceived of as dinosaurs, are not taxonomically classified as dinosaurs. Pterosaurs are distantly related to dinosaurs, being members of the clade Ornithodira. The other groups mentioned are, like dinosaurs and pterosaurs, members of Sauropsida (the reptile and bird clade), except Dimetrodon (which is a synapsid). None of them had the erect hind limb posture characteristic of true dinosaurs. Dinosaurs were the dominant terrestrial vertebrates of the Mesozoic Era, especially the Jurassic and Cretaceous periods. Other groups of animals were restricted in size and niches; mammals, for example, rarely exceeded the size of a domestic cat and were generally rodent-sized carnivores of small prey. Dinosaurs have always been recognized as an extremely varied group: over 900 non-avian dinosaur genera have been confidently identified (2018) with 1,124 species (2016). Estimates put the total number of dinosaur genera preserved in the fossil record at 1850, nearly 75% still undiscovered, and the number that ever existed (in or out of the fossil record) at 3,400. A 2016 estimate put the number of dinosaur species living in the Mesozoic at 1,543–2,468, compared to the number of modern-day birds (avian dinosaurs) at 10,806 species.
A tandem mass spectrometer is one capable of multiple rounds of mass spectrometry, usually separated by some form of molecule fragmentation. For example, one mass analyzer can isolate one peptide from many entering a mass spectrometer. A collision cell then stabilizes the peptide ions while they collide with a gas, causing them to fragment by collision-induced dissociation (CID). A further mass analyzer then sorts the fragments produced from the peptides. Tandem MS can also be done in a single mass analyzer over time, as in a quadrupole ion trap. There are various methods for fragmenting molecules for tandem MS, including collision-induced dissociation (CID), electron capture dissociation (ECD), electron transfer dissociation (ETD), infrared multiphoton dissociation (IRMPD), blackbody infrared radiative dissociation (BIRD), electron-detachment dissociation (EDD) and surface-induced dissociation (SID). An important application using tandem mass spectrometry is in protein identification. Tandem mass spectrometry enables a variety of experimental sequences. Many commercial mass spectrometers are designed to expedite the execution of such routine sequences as selected reaction monitoring, precursor ion scanning, product ion scanning, and neutral loss scanning.

== 1980 incident == On the evening of December 21, 1980, while celebrating Christmas with her family at their mansion, Clarendon Court, in Newport, Rhode Island, she again displayed confusion and lack of coordination. She was put to bed by her family, but in the morning she was discovered unconscious on the bathroom floor. She was taken to the hospital where it became clear that this time she had suffered severe enough brain injury to produce a persistent vegetative state. Although clinical features resembled a drug overdose, some of the laboratory evidence suggested hypoglycemia. The Court of Appeal ordered disclosure of the notes taken by the Auersperg children's attorney. These showed that Claus von Bülow did not want to terminate life support, as had been alleged. Because of the increased marital tensions between Claus and Sunny von Bülow in the fall of 1980, her children were suspicious that her brain injury was the result of foul play by him. Her two eldest children persuaded Richard H. Kuh, the former New York County District Attorney, to investigate the possibility Claus von Bülow had attempted the murder of their mother. After the gathering of evidence, Rhode Island prosecutors presented the case to a grand jury who returned an indictment, and in July 1981, he was charged with two counts of attempted murder.
Kayser–Fleischer rings, a rusty brown discoloration at the outer rims of the iris due to copper deposition noted in 90% of patients, become evident as copper begins to accumulate and affect the nervous system. Almost always, death occurs if the disease is untreated. Fortunately, identification of the mutations in the Wilson ATPase gene underlying most cases of Wilson's disease has made DNA testing for diagnosis possible. If diagnosed and treated early enough, patients with Wilson's disease may live long and productive lives. Wilson's disease is managed by copper chelation therapy with D-penicillamine (which picks up and binds copper and enables patients to excrete excess copper accumulated in the liver), therapy with zinc sulfate or zinc acetate, and restrictive dietary metal intake, such as the elimination of chocolate, oysters, and mushrooms. Zinc therapy is now the treatment of choice. Zinc produces a mucosal block by inducing metallothionein, which binds copper in mucosal cells until they slough off and are eliminated in the feces. and it competes with copper for absorption in the intestine by DMT1 (Divalent Metal transporter 1). More recently, experimental treatments with tetrathiomolybdate showed promising results. Tetrathiomolybdate appears to be an excellent form of initial treatment in patients who have neurologic symptoms. In contrast to penicillamine therapy, initial treatment with tetrathiomolybdate rarely allows further, often irreversible, neurologic deterioration.
The In-N-Out menu consists of three burger varieties: hamburger, cheeseburger, and "Double-Double" (two hamburger patties and two slices of cheese). French fries and fountain drinks are available, as well as three flavors of milkshakes. The hamburgers come with lettuce, tomato, with or without onions (the customer is asked upon ordering, and may have them fresh or grilled), and a sauce, which is called "spread" (a Thousand Island dressing variant). There are additional named items not on the menu, but available at every In-N-Out. These variations reside on the chain's "secret menu", though the menu is accessible on the company's website. These variations include 3×3 (which has three patties and three slices of cheese), 4×4 (four patties and four slices of cheese), Neapolitan shakes, grilled cheese sandwich (consists of the same ingredients as the burgers except the meat, plus two slices of melted cheese), Protein Style (wrap with lettuce; consists of the same ingredients as the burgers except buns), and Animal Style (cooked in a thin layer of mustard, adding condiments including pickles, grilled onions, and extra spread). Animal Style fries come with two slices of melted cheese, spread, and grilled onions on top. Whole or sliced chili peppers are also available by request. Both Protein and Animal Style are house specialties that the company has trademarked because of their association with the chain.

Semax is a synthetic seven-amino-acid peptide derived from a fragment of corticotropin. It is used in Russia as a nasal preparation, while elsewhere it is studied as a research compound. It is not approved as a medicine in most countries.
Its sequence corresponds to the 4-10 region of corticotropin extended by three residues. This fragment lacks the region responsible for adrenal steroid release, so it is explored for neural rather than hormonal effects. The relationship explains the compound's classification among ACTH-derived peptides.
It holds approval in Russia for several neurological indications as a nasal spray or drop formulation. Regulatory agencies in the United States and the European Union have not approved it. Products sold elsewhere are generally labeled for research use only.
It is a synthetic peptide of seven amino acids. Its backbone corresponds to a fragment of adrenocorticotropic hormone extended at the carboxyl end. The material is distributed as a lyophilized solid for laboratory use.
