Lumi-LSD
Lumi-LSD, also known as 10-hydroxy-9,10-dihydro-LSD or as ''N'',''N''-diethyl-9,10-dihydro-10-hydroxylysergamide, is a lysergamide and chemical degradation product of the psychedelic drug lysergic acid diethylamide (LSD). LSD is converted into lumi-LSD by exposure to light, specifically ultraviolet light. "A second and separate point of instability is the double bond that lies between this 8-position and the aromatic ring. Water or alcohol can add to this site, especially in the presence of light (sunlight with its ultraviolet energy is notoriously bad) to form a product that has been called lumi-LSD, which is totally inactive in man." Lumi-LSD might also be a metabolite of LSD, but this remains unconfirmed. Pharmacology Lumi-LSD showed 0.01% (i.e., 10,000-fold lower) of the antiserotonergic activity of LSD in the isolated rat uterus ''in vitro''. As such, lumi-LSD was regarded as essentially inactive in this assay. Similarly, lumi-LSD shows abolished physiological and behavior ...

9,10-Dihydro-LSD
9,10-Dihydro-LSD, or 9,10-DH-LSD, also known simply as dihydro-LSD (DH-LSD) or as 9,10-dihydrolysergic acid diethylamide, is a non-hallucinogenic serotonin receptor modulator of the lysergamide family related to lysergic acid diethylamide (LSD). It is the analogue of LSD in which the 9,10- double bond in the D ring of the ergoline ring system has been hydrogenated. Use and effects In spite of its potent serotonin 5-HT2A receptor agonism, 9,10-dihydro-LSD was found to be inactive in terms of psychedelic effects in humans. Whereas LSD is active at an oral dose of 1μg/kg (70μg for a 70-kg person), 9,10-dihydro-LSD was inactive orally at doses of up to 50μg/kg (3.5mg for a 70-kg person). As such, 9,10-dihydro-LSD does not produce psychedelic effects at doses of up to 50times the effective doses of LSD, demonstrating less than 2% of the potency of LSD in this regard. Side effects Despite lack psychedelic effects, 9,10-dihydro-LSD has nonetheless been reported to produce strong a ...

Iso-LSD
Iso-LSD, also known as ''d''-iso-LSD, (+)-iso-LSD, or (5''R''-8''S'')-LSD, as well as ''N'',''N''-diethylisolysergamide, is a serotonin receptor modulator of the substituted lysergamide, lysergamide family related to lysergic acid diethylamide (LSD). It is the 8-position epimer of LSD, with iso-LSD being 8α (8''S'') and LSD being 8β (8''R''). Iso-LSD is also the ''N'',''N''-diethyl chemical derivative, derivative of isoergine (isolysergic acid amide; iso-LSA), a constituent found in morning glory seeds. Iso-LSD is one of four possible stereoisomers of LSD. Use and effects According to Albert Hofmann and colleagues, iso-LSD is inactive as a psychedelic drug, psychedelic in humans at doses of up to 500μg, which is up to 25times the minimum given doses of LSD (i.e., 20–50μg).} In other sources, iso-LSD was also stated as being inactive at doses of up to 50μg/kg (3.5mg for a 70-kg person), whereas LSD is active at a dose of 1μg/kg (70μg for a 70-kg person). Hence, iso-LSD is ...

Substituted Lysergamide
Lysergamides, also known as ergoamides or as lysergic acid amides, are amides of lysergic acid (LA). They are ergolines, with some lysergamides being found naturally in ergot as well as other fungi. Lysergamides are notable in containing embedded phenethylamine and tryptamine moieties within their ergoline ring system. The simplest lysergamides are ergine (lysergic acid amide; LSA) and isoergine (iso-lysergic acid amide; iso-LSA). In terms of pharmacology, the lysergamides include numerous serotonin and dopamine receptor agonists, most notably the psychedelic drug lysergic acid diethylamide (LSD) but also a number of pharmaceutical drugs like ergometrine, methylergometrine, methysergide, and cabergoline. Various analogues of LSD, such as the psychedelics ALD-52 (1A-LSD), ETH-LAD, LSZ, and 1P-LSD and the non-hallucinogenic 2-bromo-LSD (BOL-148), have also been developed. Ergopeptines like ergotamine, dihydroergotamine, and bromocriptine are also lysergamides, but with a ...

Electroencephalogram
Electroencephalography (EEG) is a method to record an electrogram of the spontaneous electrical activity of the brain. The bio signals detected by EEG have been shown to represent the postsynaptic potentials of pyramidal neurons in the neocortex and allocortex. It is typically non-invasive, with the EEG electrodes placed along the scalp (commonly called "scalp EEG") using the International 10–20 system, or variations of it. Electrocorticography, involving surgical placement of electrodes, is sometimes called "intracranial EEG". Clinical interpretation of EEG recordings is most often performed by visual inspection of the tracing or quantitative EEG analysis. Voltage fluctuations measured by the EEG bio amplifier and electrodes allow the evaluation of normal brain activity. As the electrical activity monitored by EEG originates in neurons in the underlying brain tissue, the recordings made by the electrodes on the surface of the scalp vary in accordance with their orie ...

Human Drug Metabolites
Humans (''Homo sapiens'') or modern humans are the most common and widespread species of primate, and the last surviving species of the genus ''Homo''. They are great apes characterized by their hairlessness, bipedalism, and high intelligence. Humans have large brains, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations. Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups — from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's developmen ...

Scientific Literature
Scientific literature encompasses a vast body of academic papers that spans various disciplines within the natural and social sciences. It primarily consists of academic papers that present original empirical research and theoretical contributions. These papers serve as essential sources of knowledge and are commonly referred to simply as "the literature" within specific research fields. The process of academic publishing involves disseminating research findings to a wider audience. Researchers submit their work to reputable journals or conferences, where it undergoes rigorous evaluation by experts in the field. This evaluation, known as peer review, ensures the quality, validity, and reliability of the research before it becomes part of the scientific literature. Peer-reviewed publications contribute significantly to advancing our understanding of the world and shaping future research endeavors. Original scientific research first published in scientific journals co ...

Fluorescent
Fluorescence is one of two kinds of photoluminescence, the emission of light by a substance that has absorbed light or other electromagnetic radiation. When exposed to ultraviolet radiation, many substances will glow (fluoresce) with colored visible light. The color of the light emitted depends on the chemical composition of the substance. Fluorescent materials generally cease to glow nearly immediately when the radiation source stops. This distinguishes them from the other type of light emission, phosphorescence. Phosphorescent materials continue to emit light for some time after the radiation stops. This difference in duration is a result of quantum spin effects. Fluorescence occurs when a photon from incoming radiation is absorbed by a molecule, exciting it to a higher energy level, followed by the emission of light as the molecule returns to a lower energy state. The emitted light may have a longer wavelength and, therefore, a lower photon energy than the absorbed rad ...

Hallucinogen
Hallucinogens, also known as psychedelics, entheogens, or historically as psychotomimetics, are a large and diverse class of psychoactive drugs that can produce altered states of consciousness characterized by major alterations in thought, mood, and perception as well as other changes. Hallucinogens are often categorized as either being psychedelics, dissociatives, or deliriants, but not all hallucinogens fall into these three classes. Examples of hallucinogens include psychedelics or serotonin 5-HT2A receptor agonists like LSD, psilocybin, mescaline, and DMT; dissociatives or NMDA receptor antagonists like ketamine, PCP, DXM, and nitrous oxide; deliriants or antimuscarinics like scopolamine and diphenhydramine; cannabinoids or cannabinoid CB1 receptor agonists like THC, nabilone, and JWH-018; κ-opioid receptor agonists like salvinorin A and pentazocine; GABAA receptor agonists like muscimol and gaboxadol; and oneirogens like ibogaine and harmaline, a ...

Psychedelic Drug
Psychedelics are a subclass of hallucinogenic drugs whose primary effect is to trigger non-ordinary mental states (known as psychedelic experiences or "trips") and a perceived "expansion of consciousness". Also referred to as classic hallucinogens or serotonergic hallucinogens, the term ''psychedelic'' is sometimes used more broadly to include various other types of hallucinogens as well, such as those which are atypical or adjacent to psychedelia like salvia and MDMA, respectively. Classic psychedelics generally cause specific psychological, visual, and auditory changes, and oftentimes a substantially altered state of consciousness. They have had the largest influence on science and culture, and include mescaline, LSD, psilocybin, and DMT. There are a large number of both naturally occurring and synthetic serotonergic psychedelics. Most psychedelic drugs fall into one of the three families of chemical compounds: tryptamines, phenethylamines, or lysergamides. T ...

Albert Hofmann
Albert Hofmann (11 January 1906 – 29 April 2008) was a Swiss chemist known for being the first to synthesize, ingest, and learn of the psychedelic effects of lysergic acid diethylamide (LSD). Hofmann's team also isolated, named and synthesized the principal psychedelic mushroom compounds psilocybin and psilocin. He authored more than 100 scientific articles and numerous books, including ''LSD: Mein Sorgenkind'' (''LSD: My Problem Child''). In 2007, he shared first place with Tim Berners-Lee on a list of the 100 greatest living geniuses published by ''The Daily Telegraph'' newspaper. Early life and education Albert Hofmann was born in Baden, Switzerland, on 11 January 1906. He was the first of four children to factory toolmaker Adolf Hofmann and Elisabeth ( Schenk) and was baptized Protestant. When his father became ill, Hofmann obtained a position as a commercial apprentice in concurrence with his studies. Owing to his father's low income, Albert's godfather paid for his edu ...

In Vitro
''In vitro'' (meaning ''in glass'', or ''in the glass'') Research, studies are performed with Cell (biology), cells or biological molecules outside their normal biological context. Colloquially called "test-tube experiments", these studies in biology and its subdisciplines are traditionally done in labware such as test tubes, flasks, Petri dishes, and microtiter plates. Studies conducted using components of an organism that have been isolated from their usual biological surroundings permit a more detailed or more convenient analysis than can be done with whole organisms; however, results obtained from ''in vitro'' experiments may not fully or accurately predict the effects on a whole organism. In contrast to ''in vitro'' experiments, ''in vivo'' studies are those conducted in living organisms, including humans, known as clinical trials, and whole plants. Definition ''In vitro'' (Latin language, Latin for "in glass"; often not italicized in English usage) studies are conducted ...
