Investigation of the μ- and κ-opioid receptor activation by eight new synthetic opioids using the [35 S]-GTPγS assay: U-47700, Isopropyl U-47700, U-49900, U-47931E, N-methyl U-47931E, U-51754, U-48520, and U-48800
Drug Test Anal 2022 Jul;14(7):1187-1199.PMID:35142070DOI:10.1002/dta.3238.
In 2009, new synthetic opioids appeared on the new psychoactive substances market. This class of new psychoactive substances generally poses a health risk due to the high affinity and potency of most of these compounds for the opioid receptors. It is known that overdoses can lead to respiratory depression and result in death. However, for many new synthetic opioids, data on toxicological and toxicokinetic properties are scarce. In the present study, eight U-opioids were investigated for their structure activity relationships at the μ- and κ-opioid receptors using a [35 S]-GTPγS assay. The potencies of the investigated U-opioids were lower than those of the reference compounds (μ-opioid receptor: hydromorphone, fentanyl; κ-opioid receptor: U-69593, U-50488). At the μ-opioid receptor, U-47700 showed the highest potency with an EC50 value of 111 nM, and at the κ-opioid receptor, U-51754 was found to be the most potent compound with an EC50 value of 120 nM. The following structural features were advantageous for activating the μ-opioid receptor: two chlorine substituents in 3,4-position at the aromatic ring, the absence of the methylene group between the amide group and the aromatic ring, a methyl group at the amide nitrogen, and/or a dimethylamine residue at the amine nitrogen of the cyclohexane ring. Further, the following structural features were beneficial for κ-opioid receptor activation: a methylene group between the amide group and the aromatic ring, a pyrrolidine residue at the amine nitrogen of the cyclohexane ring, a methyl group at the amide nitrogen, and/or a chlorine substitution at the 3,4-position of the aromatic ring.
Analysis of the Illicit Opioid U-48800 and Related Compounds by LC-MS-MS and Case Series of Fatalities Involving U-48800
J Anal Toxicol 2022 Feb 14;46(1):17-24.PMID:33237987DOI:10.1093/jat/bkaa180.
We report a method for the detection and quantitation of 12 drugs and 2 metabolites in the same structural class as the illicit mu-opioid agonist U-47700 in human whole blood. These substances are either known or suspected to be present as potential novel opioids in illicit drug markets. The general class of these drugs was developed in pharmaceutical research programs in the 1970s, but these drugs have recently become of concern for overdoses and death in opioid users in the USA and internationally. The scope of analysis included the following compounds: methylenedioxy U-47700, ethylenedioxy U-47700, ethylenedioxy U-51754, U-69593, U-47931E (bromadoline), U-47700, U-48800, U-49900, U-51754, U-50488, propyl U-47700 and Isopropyl U-47700. Additionally, two metabolites N,N-didesmethyl U-47700 and desmethyl U-47700 were also included in the scope. Drugs were extracted from human whole blood using solid-phase extraction, and the extracts were analyzed by liquid chromatography--tandem mass spectrometry. The assay was validated with respect to bias, carryover, interference, within-run and between-run precision, and accuracy. Eight medicolegal death investigation cases that had screened positive for U-48800 by liquid chromatography--time-of-flight mass spectrometry were successfully confirmed and quantified using this method. The mean and median concentrations of U-48800 in these cases were 2.5 (±2.1) and 1.8 ng/mL, respectively, with a range of concentrations of 0.27-6.2 ng/mL. Case history information including the presence of other drugs in combination are described and discussed.
