CRL-40,940 (also known as flmodafinil, bisfluoromodafinil and lauflumide) is the bisfluoro analog of modafinil. [1] [2] [3] [4] [5] It is a eugeroic as well as a weak dopamine reuptake inhibitor. Its inventors claim that it is more effective than modafinil and adrafinil, with fewer side effects. It was patented in 2013, and pre-clinical trials have been underway since December 2015. [6]
Modafinil, sold under the brand name Provigil among others, is a wakefulness-promoting medication used primarily to treat narcolepsy. 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 age 17.
Stimulants are a class of drugs that increase the activity of the brain and the spinal cord. They are used for various purposes, such as enhancing alertness, attention, motivation, cognition, mood, and physical performance. Some of the most common stimulants are caffeine, nicotine, amphetamines, cocaine, and modafinil.
A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron. This results in increased extracellular concentrations of dopamine and increase in dopaminergic neurotransmission.

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.
Armodafinil (trade name Nuvigil) is the enantiopure compound of the eugeroic modafinil (Provigil). It consists of only the (R)-(−)-enantiomer of the racemic modafinil. Armodafinil is produced by the pharmaceutical company Cephalon Inc. and was approved by the U.S. Food and Drug Administration (FDA) in June 2007. In 2016, the FDA granted Mylan rights for the first generic version of Cephalon's Nuvigil to be marketed in the U.S.
Cephalon, Inc. was an American biopharmaceutical company co-founded in 1987 by pharmacologist Frank Baldino, Jr., neuroscientist Michael Lewis, and organic chemist James C. Kauer—all three former scientists with the DuPont Company. Baldino served as Cephalon's chairman and chief executive officer, until his death in December 2010. The company's name comes from the adjective "cephalic" meaning "related to the head or brain", as it was established primarily to pursue treatments for neurodegenerative diseases.
Title 35 of the United States Code is a title of United States Code regarding patent law. The sections of Title 35 govern all aspects of patent law in the United States. There are currently 37 chapters, which include 376 sections, in Title 35.
Buflomedil, sold under the brand name Loftyl, is a vasoactive drug used to treat claudication or the symptoms of peripheral arterial disease. It is currently not approved by the Food and Drug Administration (FDA) for use in the United States.
Bacampicillin (INN) is a penicillin antibiotic. It is a prodrug of ampicillin with improved oral bioavailability.
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.
Eugeroics, also known as wakefulness-promoting agents and wakefulness-promoting drugs, are a class of drugs that promote wakefulness and alertness. They are medically indicated for the treatment of certain sleep disorders including excessive daytime sleepiness (EDS) in narcolepsy or obstructive sleep apnea (OSA). Eugeroics are also often prescribed off-label for the treatment of EDS in idiopathic hypersomnia. In contrast to classical psychostimulants, such as methylphenidate and amphetamine, which are also used in the treatment of these disorders, eugeroics typically do not produce marked euphoria, and, consequently, have a lower addictive potential.
JZ-IV-10 is a piperidine derivative related to cocaine which acts as a highly potent serotonin–norepinephrine–dopamine reuptake inhibitor. The eugeroic modafinil was used as a lead to fuel this compound's discovery.
Tedatioxetine is an experimental antidepressant that was discovered by scientists at Lundbeck; in 2007 Lundbeck and Takeda entered into a partnership that included tedatioxetine but was focused on another, more advanced Lundbeck drug candidate, vortioxetine.
CRL-40,941 (also known as fladrafinil and fluorafinil) is a eugeroic closely related to adrafinil and modafinil. It is the bis(p-fluoro) ring-substituted derivative of adrafinil. CRL-40,941 was found to produce antiaggressive effects in animals, which adrafinil does not produce; it purportedly 3–4 times more potent than adrafinil.
JTE 7-31 is a selective cannabinoid receptor agonist invented by Japan Tobacco. It is a reasonably highly selective CB2 agonist, but still retains appreciable affinity at CB1, with a Ki of 0.088nM at CB2 vs 11nM at CB1.
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.
Modafinil sulfone (code name CRL-41056) is an achiral, oxidized metabolite of modafinil, a wakefulness-promoting agent. It is one of two major circulating metabolites of modafinil, the other being modafinil acid. Modafinil sulfone is also a metabolite of the modafinil prodrug, adrafinil. Modafinil sulfone is also a metabolite of armodafinil, the (R)-(–)-enantiomer of modafinil, as oxidation to the sulfone removes the chiral center at the sulfur atom. Modafinil sulfone has been described as inactive, and similarly to modafinil acid, does not appear to contribute to the wakefulness-promoting effects of modafinil. However, like modafinil, modafinil sulfone was found to show anticonvulsant properties in animals, indicating that it does possess some biological activity.

CE-123 is an analog of modafinil, the most researched of a series of structurally related heterocyclic derivatives. In animal studies, CE-123 was found to improve performance on tests of learning and memory in a manner consistent with a nootropic effect profile.
