RDS03-94
RDS03-94, or RDS3-094, is an atypical dopamine reuptake inhibitor that was derived from the wakefulness-promoting agent modafinil. It has substantially higher affinity and potency in terms of dopamine transporter (DAT) inhibition than modafinil (Ki = 39.4nM vs. 8,160nM) whilst retaining the atypical DAT blocker profile of modafinil. However, RDS03-94 also has high affinity for the sigma σ1 receptor (Ki = 2.19nM). RDS03-94 shows some reversal of tetrabenazine-induced motivational deficits in animals and hence may have the capacity to produce pro-motivational effects. However, it appears to be less effective than certain other related agents, like JJC8-088. RDS03-94 is under development for the treatment of psychostimulant use disorder. The drug was first described in the scientific literature : ''For a broader class of literature, see Academic publishing.'' Scientific literature comprises scholarly publications that report original empirical and theoretical work i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Modafinil Analogues And Derivatives
This page lists chemical compounds similar to modafinil, known as modafinil analogues and derivatives. These are structural analogues and derivatives of modafinil, a drug that affects dopamine levels in the brain in an unusual way (atypical dopamine reuptake inhibitor or DRI). Modafinil is a drug that helps keep people awake and alert (wakefulness-promoting agent or "eugeroic"). Most of the listed modafinil analogues are drugs that specifically target dopamine reuptake (reabsorption of a neurotransmitter by a neurotransmitter transporter) with stronger effects ( selective DRIs with improved potency) compared to modafinil. The modafinil analogues are of interest in the potential treatment of a condition involving the misuse of stimulant drugs ( psychostimulant use disorder or PSUD), as drugs that help increase motivation ( pro-motivational agents) to treat motivational disorders, and for treatment of neurodegenerative diseases such as Alzheimer's disease. Modafinil analogues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pro-motivational Agents
A motivation-enhancing drug, also known as a pro-motivational drug, is a drug which increases motivation. Drugs enhancing motivation can be used in the treatment of motivational deficits, for instance in depression, schizophrenia, and attention deficit hyperactivity disorder (ADHD). They can also be used in the treatment of disorders of diminished motivation (DDMs), including apathy, abulia, and akinetic mutism, disorders that can be caused by conditions like stroke, traumatic brain injury (TBI), and neurodegenerative diseases. Motivation-enhancing drugs are used non-medically by healthy people to increase motivation and productivity as well, for instance in educational contexts. There are limited clinical data on medications in treating motivational deficits and disorders. In any case, drugs used for pro-motivational purposes are generally dopaminergic agents, for instance dopamine reuptake inhibitors (DRIs) like methylphenidate and modafinil, dopamine releasing agents (DRAs ...

Dopamine Reuptake Inhibitor
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stimulant Use Disorder
Stimulant use disorder is a type of substance use disorder that involves the non-medical use of stimulants. It is defined in the DSM-5 as "the continued use of amphetamine-type substances, cocaine, or other stimulants leading to clinically significant impairment or distress, from mild to severe". These psychoactive drugs, known as stimulants, are the most widely used drugs in the world today. Approximately 200 million Americans have used some type of stimulant in the past year alone. Definition A psychoactive drug, such as a stimulant, is a chemical or substance that affects one’s behavior, mind, and body. A stimulant can be smoked, injected, snorted, taken in pill form, chewed, and even ingested in the form of a drink. Synthetic stimulants are becoming increasingly popular as users attempt to alter the chemicals in drugs to create different reactions, and ultimately steer clear of jail time, legal penalties, and detection in drug screening efforts. If a substance is used ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stimulants
Stimulants (also often referred to as psychostimulants or colloquially as uppers) is an overarching term that covers many drugs including those that increase activity of the central nervous system and the body, drugs that are pleasurable and invigorating, or drugs that have sympathomimetic effects. Stimulants are widely used throughout the world as prescription medicines as well as without a prescription (either legally or illicitly) as performance-enhancing or recreational drugs. Among narcotics, stimulants produce a noticeable crash or '' comedown'' at the end of their effects. The most frequently prescribed stimulants as of 2013 were lisdexamfetamine (Vyvanse), methylphenidate (Ritalin), and amphetamine (Adderall). It was estimated in 2015 that the percentage of the world population that had used cocaine during a year was 0.4%. For the category "amphetamines and prescription stimulants" (with "amphetamines" including amphetamine and methamphetamine) the value was 0.7%, and ...

Sigma Receptor Modulators
Sigma (; uppercase Σ, lowercase σ, lowercase in word-final position ς; grc-gre, σίγμα) is the eighteenth letter of the Greek alphabet. In the system of Greek numerals, it has a value of 200. In general mathematics, uppercase Σ is used as an operator for summation. When used at the end of a letter-case word (one that does not use all caps), the final form (ς) is used. In ' (Odysseus), for example, the two lowercase sigmas (σ) in the center of the name are distinct from the word-final sigma (ς) at the end. The Latin letter S derives from sigma while the Cyrillic letter Es derives from a lunate form of this letter. History The shape (Σς) and alphabetic position of sigma is derived from the Phoenician letter ( ''shin''). Sigma's original name may have been ''san'', but due to the complicated early history of the Greek epichoric alphabets, ''san'' came to be identified as a separate letter in the Greek alphabet, represented as Ϻ. Herodotus reports that "san" was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondary Alcohols
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 ...

Experimental Drugs
An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated. Experiments vary greatly in goal and scale but always rely on repeatable procedure and logical analysis of the results. There also exist natural experimental studies. A child may carry out basic experiments to understand how things fall to the ground, while teams of scientists may take years of systematic investigation to advance their understanding of a phenomenon. Experiments and other types of hands-on activities are very important to student learning in the science classroom. Experiments can raise test scores and help a student become more engaged and interested in the material they are learning, especially when used over time. Experiments can vary from personal and informal natural comparisons ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Enantiopure Drugs
An enantiopure drug is a pharmaceutical that is available in one specific enantiomeric form. Most biological molecules (proteins, sugars, etc.) are present in only one of many chiral forms, so different enantiomers of a chiral drug molecule bind differently (or not at all) to target receptors. Chirality can be observed when the geometric properties of an object is not superimposable with its mirror image. Two forms of a molecule are formed (both mirror images) from a chiral carbon, these two forms are called enantiomers. One enantiomer of a drug may have a desired beneficial effect while the other may cause serious and undesired side effects, or sometimes even beneficial but entirely different effects. The desired enantiomer is known as an eutomer while the undesired enantiomer is known as the distomer. When equal amounts of both enantiomers are found in a mixture, the mixture is known as a racemic mixture. If a mixture for a drug does not have a 1:1 ratio of its enantiomers it is a ...
