Modafinil, sold under the brand name Provigil among others, is a wakefulness-promoting medication used primarily to treat narcolepsy, a sleep disorder characterized by excessive daytime sleepiness and sudden sleep attacks. Modafinil is also approved for stimulating wakefulness in people with sleep apnea and shift work sleep disorder. It is taken by mouth. Modafinil is not approved by the US Food and Drug Administration (FDA) for use in people under 17 years old.
Nootropics, colloquially brain supplements, smart drugs and cognitive enhancers, are natural, semisynthetic or synthetic compounds which purportedly improve cognitive functions, such as executive functions, attention or memory.
Adrafinil, sold under the brand name Olmifon, is a wakefulness-promoting medication that was formerly used in France to improve alertness, attention, wakefulness, and mood, particularly in the elderly. It was also used off-label by individuals who wished to avoid fatigue, such as night workers or others who needed to stay awake and alert for long periods of time. Additionally, the medication has been used non-medically as a novel vigilance-promoting agent.
Racetams, also sometimes known simply as pyrrolidones, are a class of drugs that share a pyrrolidone nucleus. Many, but not all, specifically have a 2-oxo-1-pyrrolidine acetamide (piracetam) nucleus. Some racetams, such as piracetam, aniracetam, oxiracetam, pramiracetam, and phenylpiracetam, are considered nootropics. Phenylpiracetam is also a stimulant. Others, such as levetiracetam, brivaracetam, and seletracetam, are anticonvulsants.
The Controlled Drugs and Substances Act is Canada's federal drug control statute. Passed in 1996 under Prime Minister Jean Chrétien's government, it repeals the Narcotic Control Act and Parts III and IV of the Food and Drugs Act, and establishes eight Schedules of controlled substances and two Classes of precursors. It provides that "The Governor in Council may, by order, amend any of Schedules I to VIII by adding to them or deleting from them any item or portion of an item, where the Governor in Council deems the amendment to be necessary in the public interest."
(+)-CPCA is a stimulant drug similar in structure to pethidine and to RTI-31, but nocaine lacks the two-carbon bridge of RTI-31's tropane skeleton. This compound was first developed as a substitute agent for cocaine.
Fluorenol, also known as hydrafinil, is an alcohol derivative of fluorene. In the most significant isomer, fluoren-9-ol or 9-hydroxyfluorene, the hydroxy group is located on the bridging carbon between the two benzene rings. Hydroxyfluorene can be converted to fluorenone by oxidation. It is a white-cream colored solid at room temperature.
N-Phenylacetyl-l-prolylglycine ethyl ester is promoted as a nootropic and is a prodrug of cyclic glycine-proline. Other names include the brand name Noopept, developmental code GVS-111, and proposed INN omberacetam.
A eugeroic, or eugregoric, also known as a vigilance-promoting agent, is a type of drug that increases vigilance. The term has been used inconsistently and in multiple ways in the scientific literature, either to refer specifically to modafinil-type wakefulness-promoting agents or to refer to wakefulness-promoting agents generally. It was first introduced in the French literature in 1987 as a descriptor for modafinil-like wakefulness-promoting drugs and for purposes of distinguishing such drugs from psychostimulants. However, the term "eugeroic" has not been widely adopted in the literature, and instead the term "wakefulness-promoting agent" has been more widely used, both for modafinil-type drugs and other agents.
Fladrafinil, also known as fluorafinil or as bisfluoroadrafinil, is a wakefulness-promoting agent related to modafinil that was never marketed. It is sold online and used non-medically as a nootropic.
Methylphenylpiracetam is a derivative of piracetam and a positive allosteric modulator of the sigma-1 receptor. It differs from phenylpiracetam by having a methyl group.
Modafinil acid (code name CRL-40467), also known as modafinilic acid or modafinil carboxylate, is one of the two major metabolites of modafinil – the other being modafinil sulfone. Modafinil acid is also a metabolite of the modafinil prodrug, adrafinil, and the (R)-(–)-enantiomer is a metabolite of armodafinil, the (R)-(–)-enantiomer of modafinil. Between 30 - 60% of modafinil is converted to modafinil acid and its half life is roughly half that of modafinil (about 7 hours). Modafinil acid seems to be inactive, and similarly to modafinil sulfone, does not appear to contribute to the wakefulness-promoting/psychostimulant effects of modafinil.
5F-AB-FUPPYCA (also known as AZ-037) is a pyrazole-based synthetic cannabinoid that is presumed to be an agonist of the CB1 receptor and has been sold online as a designer drug. It was first detected by the EMCDDA as part of a seizure of 540 g white powder in France in February 2015.
Flmodafinil, also known as bisfluoromodafinil and lauflumide, is a wakefulness-promoting agent related to modafinil which has been developed for treatment of a variety of different medical conditions. These include chronic fatigue syndrome, idiopathic hypersomnia, narcolepsy, attention deficit hyperactivity disorder (ADHD), and Alzheimer's disease. Aside its development as a potential pharmaceutical drug, flmodafinil is sold online and used non-medically as a nootropic.
RDS03-94, or RDS3-094, is an atypical dopamine reuptake inhibitor that was derived from the wakefulness-promoting agent modafinil.
JJC8-016 is an atypical dopamine reuptake inhibitor (DRI) that was derived from modafinil. It was an early lead in the development of novel modafinil analogues with improved properties for potential use in the treatment of psychostimulant use disorder (PSUD).
JJC8-091 is an atypical dopamine reuptake inhibitor (DRI) that was derived from modafinil. It is a lead compound for potential treatment of psychostimulant use disorder (PSUD) and is under development by Encepheal Therapeutics for use as a pharmaceutical drug.
JJC8-089 is a dopamine reuptake inhibitor (DRI) that was derived from modafinil and is related to JJC8-016, JJC8-088, and JJC8-091. Its affinity (Ki) for the dopamine transporter (DAT) is 37.8 nM, for the norepinephrine transporter (NET) is 11,820 nM, for the serotonin transporter (SERT) is 6,800 nM, and for the sigma σ1 receptor is 2.24 nM. It also has significant affinity for several dopamine receptors. JJC8-089 has substantially higher affinity for the DAT than modafinil. The drug shows pro-motivational effects in animals. It was first described in the scientific literature by 2016.
