Pharmacomicrobiomics

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Oral medications encounter gut commensal microbes that participate directly and indirectly in drug effects through metabolism, interactions with drug metabolites, or production of substrates that compete with drugs for drug‐metabolizing enzymes, consequently influencing drug pharmacokinetics.

Association Discovery Approach in Healthcare Big Data to Identify Drug Safety and Drug Repurposing Signals

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Data science approaches have been increasingly implemented in healthcare big data to evaluate the safety and effectiveness of drugs. Association discovery is a data mining approach that finds potentially associated elements in high‐dimensional data. We present a novel implementation of the association discovery approach in longitudinal healthcare data ...

Post‐Mortem Identification and Toxicological Findings of Fluetonitazepyne and Isotonitazepyne

open access: yesDrug Testing and Analysis, EarlyView.
In early 2025, five death cases in Finland tested positive for fluetonitazepyne and one for isotonitazepyne in urine drug screening. A peak corresponding to O‐dealkylated fluetonitazepyne, the 4‐OH‐nitazepyne metabolite, was present in all fluetonitazepyne‐positive urine samples and was later used in the identification of isotonitazepynein one fatal ...

Evaluation of Therapeutic Opioids in Hair of Neonatal and Pediatric Patients

open access: yesDrug Testing and Analysis, EarlyView.
This study investigated the incorporation of novel and traditional medically used opioids into the hair of 118 pediatric and neonatal patients. Concentrations (median [range]) in hair were as follows: fentanyl: 4.03 pg/mg [0.10–343], sufentanil: 0.31 pg/mg [0.10–8.64], remifentanil: 0.14 pg/mg [0.10–0.43], and morphine: 27.4 pg/mg [1.0–1870].

The influence of μ-opioid and noradrenaline reuptake inhibition in the modulation of pain responsive neurones in the central amygdala by tapentadol in rats with neuropathy [PDF]

open access: yes, 2015
Treatments for neuropathic pain are either not fully effective or have problematic side effects. Combinations of drugs are often used. Tapentadol is a newer molecule that produces analgesia in various pain models through two inhibitory mechanisms, namely

Intramolecular Heck Reactions of Cyclic Sulfonamides: Regiochemical Trends and Reductive Cleavage

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
The synthesis of a new class of cyclic sulfonamides and their subsequent conversion into substituted N‐heterocycles is reported. Methyl‐substituted tetrahydropyridine and tetrahydro‐azepine Heck precursors are prepared and cyclized to provide a variety of regioisomeric products.
