Synthesis and insecticidal activities of 4-(propargyloxy) benzenesulfonamide derivatives

Journal of Asian Natural Products Research, 2022
A series of 4-(propargyloxy) benzenesulfonamide derivatives with different substituents on the benzene ring were synthesized and evaluated for their insecticidal activity. Some of the compounds showed good insecticidal activity against Mythimna separata, and the LC50 value of the most active compound B2.5 was 0.235 mg/ml. Ultrastructural changes in the

Recent Advances in Intramolecular C─N Bond Formation for Pyrrolidine Synthesis

ChemistryOpen, Volume 15, Issue 6, June 2026.
This review highlights synthetic advances (2013–2025) in intramolecular C─N bond formation for constructing the pharmaceutically relevant pyrrolidine core. The review is organized into five methodological clusters: 1) intramolecular alkene/alkyne amination; 2) tandem annulations, which involve C─N bond formation as the key step; 3) nucleophilic ...

Radioiodination of Two Carborane‐Based Dual Cyclooxygenase‐2/5‐Lipoxygenase Inhibitors and Their In Vitro and In Vivo Evaluation

ChemBioChem, Volume 27, Issue 7, 14 April 2026.
Two dicarbadodecaborane(12)‐based dual cyclooxygenase‐2/5‐lipoxygenase (COX‐2/5‐LO) inhibitors were 123I‐labeled. Refinement of labeling and formulation conditions and extensive in vitro characterization are presented. Cell uptake studies in COX‐2‐ and 5‐LO‐overexpressing cell lines showed COX‐2‐independent and partly 5‐LO‐dependent uptake.

Bimetallic M2B Boride Nanoparticles: A Robust and Recyclable Platform for Dehydration‐Driven Condensation of Aldehydes

ChemistryOpen, Volume 15, Issue 4, April 2026.
Metal borides (MBs) emerge as a versatile class of nanomaterials, featuring high stability and bifunctional Lewis‐acidic/basic active sites. Despite these properties, their applications in CN bond formation are less explored. Herein, we report the first systematic use of M2B‐type boride nanoparticles as efficient and magnetically recoverable catalysts
