Fluorenol
Fluorenol, also known as hydrafinil, is an Alcohol (chemistry), 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. Toxicity Fluorenol is toxic to aquatic organisms including algae, bacteria, and crustaceans. Fluorenol was patented as an insecticide in 1939, and is an algaecide against the green algae ''Dunaliella Dunaliella bioculata, bioculata''.MSDS Its toxicity and carcinogenicity in humans are unknown. Mechanism of action The exact mechanism of action of fluorenol is unknown. The lipophilicity of fluorenol (LogP 2.4) is hig ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorenone
Fluorenone is an aromatic organic compound with the chemical formula C13H8O. It is bright fluorescent yellow in color and is a solid at room temperature. It can be synthesised from fluorene with the addition of glacial acetic acid and sodium hypochlorite solution, undergoing an oxidation reaction. Several substituted fluorenones are biologically active as antibiotic, anticancer, antiviral, or neuromodulatory compounds. Some substituted azafluorenones are biologically active, such as the naturally occurring antimicrobial compound onychine (1-methyl-4-azafluorenone). The compound 1,8-diazafluoren-9-one is used for fingerprint detection. Medicine uses Fluorenone has uses in medicinal chemistry, for example in the synthesis of Paranyline, IPS-339 0979-28-4 Fanthridone, & SKF 550 8776-87-3among others. A pair of patents was disclosed for an analog of amitriptyline that relies on fluorenone starting material 684-13-3Dr Kurt Stach, et al. DE1150976 (1963 to Roche Diagnostics ...

Dopamine Reuptake Inhibitors
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. DRIs are used in the treatment of attention-deficit hyperactivity disorder (ADHD) and narcolepsy for their psychostimulant effects, and in the treatment of obesity and binge eating disorder for their appetite suppressant effects. They are sometimes used as antidepressants in the treatment of mood disorders, but their use as antidepressants is limited given that strong DRIs have a high abuse potential and legal restrictions on their use. Lack of dopamine reuptake and the increase in extracellular levels of dopamine have been linked ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorenes
Fluorene , or 9''H''-fluorene is an organic compound with the formula (C6H4)2CH2. It forms white crystals that exhibit a characteristic, aromatic odor similar to that of naphthalene. It has a violet fluorescence, hence its name. For commercial purposes it is obtained from coal tar. It is insoluble in water and soluble in many organic solvents. Although sometimes classified as a polycyclic aromatic hydrocarbon, the five-membered ring has no aromatic properties. Fluorene is mildly acidic. Synthesis, structure, and reactivity Although fluorene is obtained from coal tar, it can also be prepared by dehydrogenation of diphenylmethane. Alternatively, it can be prepared by the reduction of fluorenone with zinc or hypophosphorous acid–iodine. The fluorene molecule is nearly planar,D. M. Burns, John Iball (1954), ''Molecular Structure of Fluorene'' Nature volume 173, p. 635. although each of the two benzene rings is coplanar with the central carbon 9.

Eugeroic
Eugeroics (originally "eugrégorique" or "eugregoric"), 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, a rare and often debilitating sleep disorder which currently has no official treatments approved by the Food and Drug Administration (FDA). 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 euphoria, and, consequently, have a lower addictive potential. Modafinil and armodafinil are each thought to act as selective, weak, atypical dopamine reuptake inhibitors (DRI), whereas adrafinil acts as a prodrug for ...

CRL-40,941
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, and is purportedly 3 - 4 times stronger than adrafinil.

CRL-40,940
CRL-40,940 (also known as flmodafinil, bisfluoromodafinil and lauflumide) is the bisfluoro analog of modafinil. 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.

Armodafinil
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. Because armodafinil has a longer half-life than modafinil does, it may be more effective at improving wakefulness in patients with excessive daytime sleepiness. Medical uses Armodafinil is currently FDA-approved to treat excessive daytime sleepiness associated with obstructive sleep apnea, narcolepsy, and shift work disorder. It is commonly used off-label to treat attention deficit hyperactivity disorder, chronic fatigue syndrome, and major depressive disorder, and has been repurposed as an adjunctive treatment for bipolar disorder.

Alcohol (chemistry)
In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl () functional group bound to a saturated carbon atom. The term ''alcohol'' originally referred to the primary alcohol ethanol (ethyl alcohol), which is used as a drug and is the main alcohol present in alcoholic drinks. An important class of alcohols, of which methanol and ethanol are the simplest examples, includes all compounds which conform to the general formula . Simple monoalcohols that are the subject of this article include primary (), secondary () and tertiary () alcohols. The suffix ''-ol'' appears in the IUPAC chemical name of all substances where the hydroxyl group is the functional group with the highest priority. When a higher priority group is present in the compound, the prefix ''hydroxy-'' is used in its IUPAC name. The suffix ''-ol'' in non-IUPAC names (such as paracetamol or cholesterol) also typically indicates that the substance is an alcohol. However, some compou ...

Adrafinil
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 nootropic. Adrafinil is a prodrug; it is primarily metabolized ''in vivo'' to modafinil, resulting in very similar pharmacological effects. Unlike modafinil, however, it takes time for the metabolite to accumulate to active levels in the bloodstream. Effects usually are apparent within 45–60 minutes when taken orally on an empty stomach. Adrafinil was marketed in France until September 2011 when it was voluntarily discontinued due to an unfavorable risk–benefit ratio. Medical uses Adrafinil is a wakefulness-promoting agent and was used to promote aler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
