Synthesis and Thermolysis of Ylidyl‐Substituted Stannylenes

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
The synthesis of an amino(ylidyl)stannylene is reported. The title compound was characterized via X‐ray diffraction and features a Sn2C2 heterocycle. Thermal treatment of the stannylene leads to the elimination of the amine. The products of the thermolysis are discussed.

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

British 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

British 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

Journal 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

Israel 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 pyrazole and pyrazoline derivatives of β-ionone: Exploring anti-inflammatory potential, cytotoxicity, and molecular docking insights

European Journal of Medicinal Chemistry Reports
In the present paper, pyrazole and pyrazoline derivatives of β-ionone were synthesized. The protocol involved intramolecular oxidative C–H amination of hydrazone to yield corresponding pyrazole in moderate to good yields.

Azide‐to‐Diazo Transformation Facilitated by Michael Addition via Phosphazide Formation

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
A new type of Michael addition based on azide‐to‐diazo conversion is disclosed. This unusual transformation proceeds via 1,4‐addition accompanied by N─N bond cleavage of phosphazide intermediates under practical conditions. The high versatility of the resulting Michael adducts enables the synthesis of a wide variety of organonitrogen compounds ...
