ChemistrySelect, Volume 11, Issue 24, 25 June 2026.In this work, the preparation of new coumarin–indazole–triazole–sulfonamide hybrids via a multistep route has been fine‐tuned. The synthesis involves nitration, reduction, formation of a sulfonamide, alkylation, and CuAAC coupling. The synthesized compounds were screened for antiproliferative activity against MDA‐MB‐231 triple‐negative breast cancer ...

Cedrela fissilis Vell. Inner Bark: LC–MS/MS‐Based Chemical Profiling and Toxicological Effects
Chemistry &Biodiversity, Volume 23, Issue 5, May 2026.ABSTRACT Investigating the mechanistic toxicity of plant extracts is essential for safety assessment. The predictive toxicological effects of Cedrela fissilis were evaluated, and LC–MS/MS‐based chemical profiling was performed. The hydroethanolic extract (HeECf) and ethyl acetate (EA) fraction were assessed in multimodel systems with different levels ...
