The illicit drug market has rapidly evolved from synthetic cannabinoids to cathinone derivatives and now a new emerging threat of synthetic opioids. These compounds were mostly developed by pharmaceutical companies during drug discovery. The new psychoactive substances are not routinely covered in drug screening and may go undetected. Recently fentanyl analogous, AH-7921, MT-45 and now U-47700 have been encountered in clinical and forensic casework. U-47700 is gaining popularity on drug user…

U-47700 and Its Analogs: Non-Fentanyl Synthetic Opioids Impacting the Recreational Drug Market

The evidence demonstrates that U-47700 is a potent μ-opioid receptor agonist, which poses a serious risk for overdosing and death, however, most analogs of U- 47700 appear to be less potent and have been detected infrequently in forensic specimens.

Determination of 37 fentanyl analogues and novel synthetic opioids in hair by UHPLC-MS/MS and its application to authentic cases

The UHPLC-MS/MS method was successfully applied to the detection and quantification of fentanyl and sufentanil in hair samples from two authentic cases and has great potential for detecting fentanyl analogues and novel synthetic opioids in forensic work.

Metabolism of novel opioid agonists U-47700 and U-49900 using human liver microsomes with confirmation in authentic urine specimens from drug users.

This study is the first to map the metabolic profiles of U-47700 and U-49900 using human liver microsomes, as well as theFirst to report any literature involving U- 49900 and analysis of case specimens.

The search for the “next” euphoric non-fentanil novel synthetic opioids on the illicit drugs market: current status and horizon scanning

Pre-emptive research on the most likely compounds to emerge next is recommended, so providing drug metabolism and pharmacokinetic data to ensure that new substances are detected early in toxicological samples is recommended.

U-47700: A Not So New Opioid.

This case report describes the first death in south-central Kansas resulting solely from U-47700 intoxication: a 26-year-old white male found dead in his bedroom with apparent drug paraphernalia.

Multiple Drug-Toxicity Involving Novel Psychoactive Substances, 3-Fluorophenmetrazine and U-47700.

The case history, autopsy and toxicological findings of a fatality involving the designer drugs 3-FPM and U-47700 are presented for the first time in the literature and the potential overlap between recreational and fatal concentrations for some NPS is discussed.

Identification and structure characterization of five synthetic opioids: 3,4-methylenedioxy-U-47700, o-methyl-acetylfentanyl, 2-thiophenefentanyl, benzoylfentanyl and benzoylbenzylfentanyl

Purpose The number of new synthetic opioids, especially fentanyl analogs, on the illicit market is increasing each year and becoming a disturbing phenomenon. Due to the very high potency, ease of



Analysis of Novel Synthetic Opioids U-47700, U-50488 and Furanyl Fentanyl by LC-MS/MS in Postmortem Casework.

Given the widespread geographical distribution and increase in prevalence in postmortem casework, toxicology testing should be expanded to include testing for "designer opioids" in cases with histories consistent with opioid overdose but with no traditional opioids present or insufficient quantities to account for death.

Analysis of MT-45, a Novel Synthetic Opioid, in Human Whole Blood by LC-MS-MS and its Identification in a Drug-Related Death.

This case illustrates the importance of considering non-traditional drugs in unexplained apparent drug-related deaths, and the requirements for acceptable linearity, precision and accuracy of MT-45.

A case of U-47700 overdose with laboratory confirmation and metabolite identification

U-47700 is a potent μ-opioid receptor agonist and has recently been used recreationally, contributing to hospitalizations and likely deaths in the community and appears to be an appropriate marker of use in a serum sample.

Development and validation of a liquid chromatography-tandem mass spectrometry method for the quantitation of synthetic cannabinoids of the aminoalkylindole type and methanandamide in serum and its application to forensic samples.

A liquid chromatography-tandem mass spectrometry method developed and fully validated according to guidelines for forensic toxicological analyses for detection and quantification of synthetic cannabinoids in biological samples originating from psychiatric inpatients, emergency units or assessment of fitness to drive is successfully applied.

Two cases of intoxication with new synthetic opioid, U-47700

Two patients presenting after insufflation of U-47700, a relatively new agent that is easy to obtain over the internet and has the potential to cause significant morbidity and mortality are reported.

Detection and identification of the designer benzodiazepine flubromazepam and preliminary data on its metabolism and pharmacokinetics.

Flubromazepam appears to have an extremely long elimination half-life of more than 100 h, which means that it could be misused in drug-withdrawal settings or in other circumstances requiring regular drug testing, and may be used indrug-facilitated crimes without being detected.

Near death from a novel synthetic opioid labeled U-47700: emergence of a new opioid class

A patient who suffered respiratory failure and depressed level of consciousness after recreationally using a novel synthetic opioid labeled U-47700 was treated with naloxone, which completely reversed his opioid poisoning.

The first reported fatality associated with the synthetic opioid 3,4-dichloro-N-[2-(dimethylamino)cyclohexyl]-N-methylbenzamide (U-47700) and implications for forensic analysis.

The search for synthetic opioids as alternatives to opium-based derivatives has provided an important impulse to drug development around the globe, but the exploration of these important discoveries has also been increasingly mined by largescale producers of these materials, which are then offered for sale.

Toxicological findings of synthetic cannabinoids in recreational users.

The toxicity of the synthetic cannabinoids seems to be worse than that of natural cannabis, probably owing to the higher potency and perhaps also to the presence of several different cannabinoids in the smoked incense and the difficulties of proper dosing.

Fatal intoxications associated with the designer opioid AH-7921.

It is reasonable to assume that no sharp dividing line exists between lethal and non-lethal concentrations, and deaths with AH-7921 seem to occur both at low and high concentrations, probably a result of different tolerance to the drug.
