Covalent drug discovery: Progress against key targets, emerging strategies and lessons learnt

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Covalent drug discovery is currently experiencing a boom in industrial and academic interest. To date, at least 75 covalent drugs have received regulatory approval, targeting both traditional target classes and more challenging proteins for which other approaches failed. In many cases, unique aspects of covalent targeting are essential for the

5‐HT2A receptor agonism by tert‐leucinamide and valinamide synthetic cannabinoids: In vitro and in vivo evidence

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose New synthetic cannabinoid receptor agonists (SCRAs) are associated with severe adverse effects, including unexpected psychiatric symptoms. These compounds are mainly active through their potent agonism on the cannabinoid receptors CB1 and CB2.

Plasma Pharmacokinetic Profile of Fipronil 1% Pour‐On in Cattle: Photodegradation and the Sustained Systemic Persistence of Fipronil Sulfone

open access: yesJournal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT This study characterized the long‐term pharmacokinetic profile of a 1% fipronil pour‐on formulation in Nellore bulls under field conditions. Seventeen animals received a single topical dose (1 mg/kg), and plasma concentrations of fipronil and its metabolites (sulfone and desulfinyl) were monitored for 175 days using LC–MS/MS.

An Exploration of Vinamidinium Salts for Frame‐Shifted Synthesis

open access: yesIsrael Journal of Chemistry, Volume 66, Issue 4, July 2026.
Oligoheterocycles are widely used in drug discovery and materials science, where they serve as attractive alternatives to peptide fragments. There is strong interest in understanding the structural correspondence between heterocycles and amino acid motifs to recapitulate key binding elements while improving metabolic stability.

Synthesis of Heterocyclic Compounds Derived from 2-Mercapto Quinoline

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2017
2-Mercapto quinoline was used as precursor for synthesis of new heterocyclic derivatives of quinoline nucleus such as pyrazole (3), pyrazolone (4), 1,3,4-oxadiazole (5) and 1,2,4-triazole (8). New Schiff bases (9a-e) were obtained from the reaction of
