Nocaine
(+)-CPCA (nocaine, 3α-carbomethoxy-4β-(4-chlorophenyl)-''N''-methylpiperidine aka CTDP 31,446) is a stimulant drug similar in structure to pethidine (an opioid that possesses NDRI actions) 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. Since then, many substituted phenylpiperidine derivatives have been discovered, hybridizing the basic nocaine structure with that of other similar molecules such as methylphenidate, meperidine and modafinil to create a large family of derivatives with a range of activity profiles and potential applications. This is a significant field of research with much ongoing work, with dozens of novel compounds having been developed although none have yet come to market. The nocaine family includes a diverse assortment of piperidine based cocaine mimetics. The parent compound nocaine was developed in an attempt to create a substitute drug for cocai ...

Cocaine
Cocaine is a tropane alkaloid and central nervous system stimulant, derived primarily from the leaves of two South American coca plants, ''Erythroxylum coca'' and ''Erythroxylum novogranatense, E. novogranatense'', which are cultivated almost exclusively in the Andes. Indigenous peoples of South America, Indigenous South Americans have traditionally used coca leaves for over a thousand years. Notably, there is no evidence that habitual coca leaf use causes addiction or withdrawal, unlike cocaine. Medically, cocaine is rarely employed, mainly as a topical medication under controlled settings, due to its high abuse potential, adverse effects, and expensive cost. Despite this, recreational drug use, recreational use is widespread, driven by its euphoric and aphrodisiac properties. Levamisole induced necrosis syndrome (LINES)-a complication of the common cocaine Lacing (drugs), cutting agent levamisole-and prenatal cocaine exposure is particularly harmful. Street cocaine is ...

RTI-274
RTI(-''4229'')-274, or 2β-((3,4-Methylenedioxyphenoxy)methyl)-3α-(4-fluorophenyl)nortropane is a phenyltropane homologue of paroxetine developed by the group led by F Ivy Carroll in the 1990s. Introduction Very few esters of phenyltropanes are actually known to have been reported. NS2330 and NS2359 both have α,β stereochemistry. NS2214 appears to have been abandoned now, RTI-336 was their latest compound. RTI decided that they wanted to make all 8 stereoisomers of the phenyltropane paroxetine homolog. *''N''-demethylating the S-α,β (1S,2S,3R) isomer resulted in a 54-fold increase in DAT IC50. In the case of N,O-Dimethyl-4-(2-naphthyl)piperidine-3-carboxylate, nocaine it is understood that the SR enantiomer is the one that should be demethylated if it is wanted to improve DAT affinity. That is the same enantiomer that is used in the production of paroxetine. Skeletal rearrangement Four years later some unrelated authors cited a skeletal rearrangement accounts f ...

Stimulant
Stimulants (also known as central nervous system stimulants, or psychostimulants, or colloquially as uppers) are a class of drugs that increase alertness. They are used for various purposes, such as enhancing attention, motivation, cognition, Mood disorder, mood, and physical activity, physical performance. Some stimulants occur naturally, while others are exclusively synthetic. Common stimulants include caffeine, nicotine, amphetamines, cocaine, methylphenidate, and modafinil. Stimulants may be subject to varying forms of regulation, or outright prohibition, depending on jurisdiction. Stimulants increase activity in the sympathetic nervous system, either directly or indirectly. Prototypical stimulants increase synaptic concentrations of neurotransmitter, excitatory neurotransmitters, particularly norepinephrine and dopamine (e.g., methylphenidate). Other stimulants work by binding to the Receptor (biochemistry), receptors of excitatory neurotransmitters (e.g., nicotine) or by ...

Sigma Receptor
Sigma receptors (σ-receptors) are protein receptors that bind ligands such as 4-PPBP (4-phenyl-1-(4-phenylbutyl) piperidine), SA 4503 (cutamesine), ditolylguanidine, dimethyltryptamine, and siramesine. There are two subtypes, sigma-1 receptors (σ1) and sigma-2 receptors (σ2), which are classified as sigma receptors for their pharmacological similarities, even though they are evolutionarily unrelated. The fungal protein ERG2, a C-8 sterol isomerase, falls into the same protein family as sigma-1. Both localize to the ER membrane, although sigma-1 is also reported to be a cell surface receptor. Sigma-2 is an EXPERA domain protein with a mostly intracellular (ER membrane) localization. Classification Because the σ-receptor was originally discovered to be agonized by benzomorphan opioids and antagonized by naltrexone, σ-receptors were originally believed to be a type of opioid receptor. When the σ1 receptor was isolated and cloned, it was found to have no structur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hyperlocomotion
Locomotor activity is a measure of animal behavior which is employed in scientific research. Hyperlocomotion, also known as locomotor hyperactivity, hyperactivity, or increased locomotor activity, is an effect of certain drugs in animals in which locomotor activity (locomotion) is increased. It is induced by certain drugs like psychostimulants and NMDA receptor antagonists and is reversed by certain other drugs like antipsychotics and certain antidepressants. Stimulation of locomotor activity is thought to be mediated by increased signaling in the nucleus accumbens, a major brain area involved in behavioral activation and motivated behavior. Hypolocomotion, also known as locomotor hypoactivity, hypoactivity, and decreased locomotor activity, is an effect of certain drugs in animals in which locomotor activity is decreased. It is a characteristic effect of many sedative agents and general anesthetics. Antipsychotics, which are dopamine receptor antagonists, and many serotonerg ...

Dopamine
Dopamine (DA, a contraction of 3,4-dihydroxyphenethylamine) is a neuromodulatory molecule that plays several important roles in cells. It is an organic chemical of the catecholamine and phenethylamine families. It is an amine synthesized by removing a carboxyl group from a molecule of its precursor chemical, L-DOPA, which is synthesized in the brain and kidneys. Dopamine is also synthesized in plants and most animals. In the brain, dopamine functions as a neurotransmitter—a chemical released by neurons (nerve cells) to send signals to other nerve cells. The brain includes several distinct dopamine pathways, one of which plays a major role in the motivational component of reward-motivated behavior. The anticipation of most types of rewards increases the level of dopamine in the brain, and many addictive drugs increase dopamine release or block its reuptake into neurons following release. Other brain dopamine pathways are involved in motor control and in controllin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dopamine Transporter
The dopamine transporter (DAT, also sodium-dependent dopamine transporter) is a membrane-spanning protein coded for in humans by the ''SLC6A3'' gene (also known as ''DAT1''), that pumps the neurotransmitter dopamine out of the synaptic cleft back into cytosol. In the cytosol, other transporters sequester the dopamine into Vesicle (biology and chemistry), vesicles for storage and later release. Dopamine reuptake via DAT provides the primary mechanism through which dopamine is cleared from synapses, although there may be an exception in the prefrontal cortex, where evidence points to a possibly larger role of the norepinephrine transporter. DAT is implicated in a number of dopamine-related disorders, including ADHD, attention deficit hyperactivity disorder, bipolar disorder, clinical depression, eating disorders, and substance use disorders. The gene that encodes the DAT protein is located on chromosome 5, consists of 15 coding exons, and is roughly 64 base pair#Length measuremen ...

Venlafaxine
Venlafaxine, sold under the brand name Effexor among others, is an antidepressant medication of the serotonin–norepinephrine reuptake inhibitor (SNRI) class. It is used to treat major depressive disorder, generalized anxiety disorder, panic disorder, and social anxiety disorder. Studies have shown that venlafaxine improves post-traumatic stress disorder (PTSD) as a recommended first-line treatment. It may also be used for chronic neuropathic pain. It is taken orally (swallowed by mouth). It is also available as the salt venlafaxine besylate (venlafaxine benzenesulfonate monohydrate) in an extended-release formulation (Venbysi XR). Common side effects include loss of appetite, constipation, dry mouth, dizziness, sweating, insomnia, drowsiness and sexual problems. Severe side effects include an increased risk of suicide, mania, and serotonin syndrome. Antidepressant withdrawal syndrome may occur if stopped. A meta-analysis of randomized trials in depression found an inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JNJ-7925476
JNJ-7925476 is a triple reuptake inhibitor antidepressant discovered by Johnson & Johnson, but never marketed. These molecules were first prepared by Bruce E. Maryanoff and coworkers during the late 1970s–1980s. The structure is a pyrroloisoquinoline core, with an overlaid benzhydryl motif. Incorporating the pyrrolidine, pyrrolidino ring onto the tetrahydroisoquinoline scaffolding markedly improves potency, although this only works for one of the available stereoisomers. JNJ-7925476 is a racemic preparation of the more potent diastereomer. Of these enantiomers, the eutomer is the (6''R'',10b''S'') stereoisomer, known as JNJ-39836966, and the distomer, (6''S'',10b''R''), is JNJ-39836732 There is some confusion over the nomenclature and Cis–trans isomerism, ''cis''/''trans'' isomeric relationship at the piperidine ring. The compounds as depicted have the carbon of the pyrrolidine carbon and the phenyl ''cis'', but Maryanoff and coworkers are of the opinion that the compound ...
