Cathinones, such as mephedrone (Meph), are often co-abused with alcoholic drinks. In the present study, we investigated the combined effects of Meph plus ethanol (EtOH) on neurotransmitter release in the nucleus accumbens (NAc) and the medial prefrontal cortex (mPFC). A guide canula was stereotaxically implanted into either the NAc or the mPFC of male Sprague-Dawley rats. Seven days after surgery, a microdialysis probe was inserted and rats were administered saline, EtOH (1 g/kg, i.p.), Meph (25 mg/kg, s...

Cathinone derivatives are notorious but still weakly characterized molecules, known mainly as components of the designer and illicit drugs. The knowledge on their acidity is scarce and incomplete, therefore, we decided to determine the pKa values for six of them: 2-methylmethcathinone, 3-methylmethcathinone, 4-methylmethcathinone, α-pyrrolidinovalerophenone, methylenedioxypyrovalerone and ephedrone. For that purpose we employed capillary electrophoresis, which is known for its accurateness in comparison to other analytical techniques...

In vitro and in vivo experiments are widely used for studying the metabolism of new psychoactive substances (NPS). The availability of such data is required for toxicological risk assessments and development of urine screening approaches. This study investigated the in vitro metabolism of the five pyrrolidinophenone-derived NPS alpha-pyrrolidinobutyrophenone (alpha-PBP), alpha-pyrrolidinopentiothiophenone (alpha-PVT), alpha-pyrrolidinohexanophenone (alpha-PHP), alpha-pyrrolidinoenanthophenone (alpha-PEP, PV8), and alpha-pyrrolidinooctanophenone (alpha-POP, PV9)...

An approach to the rapid determination of the structures of novel synthetic cathinone designer drugs, also known as bath salts, is reported. While cathinones fragment so extensively by electron impact mass spectrometry that their mass spectra often cannot be used to identify the structure, collision-induced dissociation (CID) direct analysis in real time-high resolution mass spectrometry (DART-HRMS) experiments furnished spectra that provided diagnostic fragmentation patterns for the analyzed cathinones. From this data, neutral loss spectra, which reflect the presence of specific chemical moieties, could be acquired...

New psychoactive substances are defined as compounds with consciousness-changing effects and have been developed simultaneously with classical drugs. They arise through structural modifications of illegal substances and are mainly produced to circumvent laws. Availability is simple, since new psychoactive substances can be purchased from the Internet. Among them many chemical drug compound classes are chiral and thus the two resulting enantiomers can differ in their effect. The aim of this study was to develop a suitable chiral high-performance liquid chromatography separation method for a broad spectrum of new psychoactive substances using cellulose tris(3,5-dichlorophenylcarbamate) as a chiral selector...

The new psychoactive substance 3,4-methylenedioxypyrovalerone (MDPV) belongs to the group of synthetic cathinones and is purchased mainly as "research chemical" or "bath salt" on the illegal drug market, also in South Bavaria. MDPV was detected in blood and urine samples from 2010 on in 50 authentic routine cases in a forensic setting. Plasma concentrations in 46 cases with available blood specimens ranged from approximately 1.0 to 301μg/L (median 23.7; mean 47.9μg/L), detected by a fully validated LC-MS/MS method...

The rising global availability of the stimulant and euphoric substances, khat and synthetic cathinones, has become a cause for concern in many countries, including the United States. Both substances are illegal in United States, although this has not deterred their use. Besides central nervous system effects, these drugs also cause sympathomimetic and orodental adverse effects, similar to those of amphetamine. Although synthetic cathinones are stronger than khat in most cases, the latter additionally contains tannins, which have astringent effects on tissues components, including those in the oral cavity...

Using the case of synthetic cathinones (commonly referred to as 'bath salts' in the US context), this paper analyses structural factors surrounding novel psychoactive substances (NPS) as contributing to the unique risk environment surrounding their use. Drawing on interviews with 39 people who use bath salts from four U.S. cities and analysis of the infrastructural, social, economic, and policy contexts, we document the unique harms related to changing contexts for illicit drug regulation, manufacture, and consumption...

Objectives: Aminoindanes ("bath salts," a class of novel psychoactive substances, NPSs) increased rapidly in popularity on the recreational drug market, particularly after mephedrone and other synthetic cathinones were banned in the UK in 2010. Novel aminoindanes continue to emerge, but relatively little is known about their effects and risks. Their history, chemistry, pharmacology, behavioral effects, pharmacokinetics, and toxicity are reviewed in this paper. Methods: Scientific literature was searched on ISI Web of Knowledge: Web of Science (WoS) during June and July 2017, using English language terms: aminoindanes such as 5,6-methylenedioxy-2-aminoindane (MDAI), 5-iodo-2-aminoindane (5-IAI), 2-aminoindane (2-AI), 5,6-methylenedioxy-N-methyl-2-aminoindane (MDMAI), and 5-methoxy-6-methyl-2-aminoindane (MMAI)...

Methylone (3,4-methylenedioxy-N-methylcathinone) is a synthetic cathinone analog of the recreational drug ecstasy. Although it is marketed to recreational users as relatively safe, fatalities due to hyperthermia, serotonin syndrome, and multi-organ system failure have been reported. Since psychopharmacological data remain scarce, we have focused our research on pharmacokinetics, and on a detailed evaluation of temporal effects of methylone and its metabolite nor-methylone on behavior and body temperature in rats...

In this report, we evaluate the concentration, pH, temperature and analyte-dependent effects on cathinone stability in preserved human urine. A total of 22 synthetic cathinones were evaluated at 100 ng/mL and 1,000 ng/mL in pH 4 and pH 8 urine over 6 months. Specimens were stored at -20°C, 4°C, 20°C and 32°C. The stability of synthetic cathinones was highly dependent on urine pH and storage temperature. Cathinones were considerably more stable in acidic urine (pH 4) at low temperature. In alkaline urine (pH 8) at 32°C, significant losses (>20%) were observed within hours for the majority of drugs...

Synthetic cathinones, frequently referred to as "bath salts", have significant abuse potential, and recent evidence suggests that these novel psychoactive substances can also produce cognitive deficits as well as cytotoxic effects. However, most of these latter findings have been obtained either using high concentrations in vitro or following non-contingent high dose administration in vivo. The present study utilized a model of long-term voluntary binge-like self-administration to determine potential detrimental effects of synthetic cathinones on cognitive function and their known underlying neural circuits, collectively referred to as neurocognitive dysfunction...

In the last few years an increasing number of new psychoactive substances (NPS), with different chemical structures (of which 37% are stimulants), have been released into the illicit drug market. Their detection and identification in biological samples is hence of great concern. The aim of this work was to develop a high-throughput and rapid method for the determination of different classes of stimulants (amphetamine-type stimulants, cathinones, phenethylamines and ketamine analogues) from blood and urine samples using GC-MS...

New psychoactive substances (NPS), namely cannabinoids, cathinones, and opioids, have surged in popularity among school-age children, resulting in serious morbidity and mortality globally. In the last decade, there has been a rapid evolution of NPS resulting in hundreds of new compounds. Little to no evidence for humans is available on most compounds. The clinical presentations of patients intoxicated with cannabinoids and cathinones are highly variable but most commonly present with a sympathomimetic toxidrome, for example, agitation, delirium, and tachycardia...

BACKGROUND: Electronic Dance Music (EDM) party attendees are often polysubstance users and are at high risk for use of new psychoactive substances (NPS). We sought to identify patterns of use of common illegal drugs among EDM party attendees, sociodemographic correlates, and use of NPS as a function of patterns of use of more common drugs to inform prevention and harm reduction. METHOD: Using time-space-sampling, 1045 individuals aged 18-40 were surveyed entering EDM parties in New York City...

Khat (Catha edulis) is a evergreen flowering shrub that is cultivated at high altitudes, especially in East Africa and the southwest of the Arabian Peninsula. The plant contains alkaloids, of which cathinone and cathine have structural similarity and pharmacological action similar to amphetamines. The leaves are, therefore, consumed in some regions as a psychoactive stimulant due to cultural beliefs and misperceptions on the health benefits of khat consumption. This resulted in a growing prevalence of khat consumption among pregnant women...

Phenethylamine derivatives are being increasingly exploited for recreational use as "designer" stimulants designed to mimic psychostimulant properties of amphetamine or other illicit substances like 3,4-methylenedioxymethamphetamine (MDMA [ecstasy]). Clandestine operations meticulously design phenethylamines so the user can bypass legal action when detected, as many of these are yet to be regulated by government authorities. Substituted phenethylamines or 2C amines, N-methoxybenzyl derivatives of the corresponding 2C amines commonly known as NBOMe compounds, and cathinones are among the most commonly abused phenethylamines...

The use of new psychoactive substances (NPS) is increasing and currently >600 NPS have been reported. However, limited information on neuropharmacological and toxicological effects of NPS is available, hampering risk characterization. We reviewed the literature on the in vitro neuronal modes of action to obtain effect fingerprints of different classes of illicit drugs and NPS. The most frequently reported NPS were selected for review: cathinones (MDPV, α-PVP, mephedrone, 4-MEC, pentedrone, methylone), cannabinoids (JWH-018), (hallucinogenic) phenethylamines (4-fluoroamphetamine, benzofurans (5-APB, 6-APB), 2C-B, NBOMes (25B-NBOMe, 25C-NBOMe, 25I-NBOMe)), arylcyclohexylamines (methoxetamine) and piperazine derivatives (mCCP, TFMPP, BZP)...
