Structure of Azadirachtin B

Zeitschrift für Naturforschung C, 1987
Abstract The structures of azadirachtin B and of detigloylazadirachtin have been determined on the basis of detailed 1H and 13C NMR spectroscopic analysis. Comparison of the data from both com pounds unequivocally proves esterification by tiglic acid at position 3. Our data thus confirm the structure as proposed by Klenk et al., J. Chem.

Efficacy of Selected Commercial Bio‐Products in Disrupting Symbiont Acquisition and Survival of Halyomorpha halys (Hemiptera: Pentatomidae)

Entomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 764-773, July 2026.
Targeting the symbiont Candidatus Pantoea carbekii offers a novel way to manage the invasive brown marmorated stink bug (Halyomorpha halys). Among the three commercial bio‐products tested, Dentamet significantly reduced symbiont acquisition and caused up to 75% nymphal mortality in laboratory conditions, which was confirmed by quantitative Real‐Time ...

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 ...

Pesticide prioritization based on risk and model diet proposals for assessing cumulative exposure to pesticide residues in the Brazilian population through food consumption

Pest Management Science, Volume 82, Issue 4, Page 3853-3873, April 2026.
A risk classification of registered pesticides in Brazil was conducted, and the contribution of food to cumulative pesticide exposure was evaluated. Model diets were proposed, based on Brazilian consumption patterns. Abstract BACKGROUND Pesticide residue exposure assessments can be carried out during both the pre‐regulation and post‐regulation phases ...
