Recombinant Monoclonal Antibodies for Detecting the Tubulin Post‐Translational Modifications Glutamylation and Lysine‐40 Acetylation

Cytoskeleton, EarlyView.
ABSTRACT Post‐translational modifications (PTMs) to tubulin subunits in microtubule filaments are thought to comprise a component of the tubulin code that specifies microtubule functions in cell physiology and animal development. Acetylation of Lysine‐40 (K40) on α‐tubulin (αTub‐K40ac) and glutamylation of both α‐ and β‐tubulin are two tubulin PTMs of ...

Non‐Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof‐of‐Concept Study

Clinical Pharmacology &Therapeutics, EarlyView.
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...

Reprocessing Mass Spectra from Therapeutic Drug Monitoring to Unveil Proton Pump Inhibitor Use and Quantify Phenoconversion of Escitalopram Metabolism in CYP2C19‐Genotyped Patients

Clinical Pharmacology &Therapeutics, EarlyView.
Escitalopram is a frequently prescribed antidepressant drug. CYP2C19 genotype is a major determinant of escitalopram metabolism and treatment outcome. However, real‐life studies show a high degree of genotype–phenotype mismatch in escitalopram metabolism.

Detection of Nitazenes in the Illicit Drug Supply Utilizing Precursor Ion Scan Methods With Paper Spray Mass Spectrometry

Drug Testing and Analysis, EarlyView.
Nitazenes are increasingly present in the illicit drug supply, complicating harm reduction efforts. We have developed a rapid, nontargeted precursor ion scan method to detect emerging nitazenes in real‐world opioid samples. The method identified multiple nitazenes, often replacing pharmaceutical opioids or mixed with fentanyl and benzodiazepines ...

Simultaneous Detection of Steroid Esters and Multi‐Class Substances in Dried Blood Spots by LC‐HRMS/MS From a Single Spot for Human Doping Control

Drug Testing and Analysis, EarlyView.
A validated LC‐HRMS/MS method enabled, for the first time, the comprehensive detection of steroid esters and multi‐class menu substances from a single dried blood spot. Following extraction, the resulting extract is split into two aliquots, reducing sample consumption and simplifying the analytical workflow.
