Divergent Total Synthesis of Denudatine Alkaloids Cochlearenine, Macrocentrine, Dictizine, 15‐Veratroyl‐17‐Acetyl‐19‐Oxodictizine, and the Proposed Structure of Acochlearine

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.
An intramolecular Mannich reaction (A/B/E/F rings) and intermolecular Diels–Alder reactions (C/D rings) afforded a cage‐like hexacyclic core skeleton of denudatine alkaloids. Derivatization of the hexacyclic intermediate enabled the first asymmetric total syntheses of four denudatine alkaloids: (–)‐cochlearenine, (–)‐macrocentrine, (–)‐dictizine, and (–

Evaluation of the pollution pressures posed by groups of chemicals on British riverine invertebrate populations

Biological Reviews, Volume 101, Issue 1, Page 106-127, February 2026.
ABSTRACT Globally, rivers receive a diverse range of chemicals, including metals, pesticides, persistent organic pollutants, petrochemicals, human and veterinary pharmaceuticals and personal care products. However, the extent to which these different chemical groups affect riverine invertebrate communities is not well defined.

Microplastic Pollution in Aquaculture: Challenges and Mitigation

Water and Environment Journal, Volume 40, Issue 1, Page 3-20, February 2026.
ABSTRACT Microplastics (MPs) have gained significant attention due to their potential environmental threat. This paper addresses MPs contamination in aquaculture, a critical concern for food safety and public health. The extensive use and disposal of plastic products in aquaculture, like netting materials, pose a significant threat to aquatic life ...
