Comparative Transcriptome Analysis of Rhynchophorus ferrugineus (Coleoptera: Curculionidae) Reveals Potential Mechanisms Involved in the Toxication and Detoxification of the External Immune Compound p-Benzoquinone Present in Oral Secretions

Insects
p-Benzoquinone (PBQ), a highly toxic compound, is the main active component in larval oral secretions of red palm weevil (RPW), Rhynchophorus ferrugineus, playing critical roles in external immunity and pathogen defense.

Catalytic, Asymmetric Inverse Electron Demand Hetero Diels-Alder Reactions of o-Benzoquinone Derivatives and Ketene Enolates

CHIMIA, 2007
We present an array of [4+2] cycloaddition reactions between ketene enolates, catalytically derived from acid chlorides and cinchona alkaloid nucleophilic catalysts in the presence of stoichiometric base, and o-benzoquinone derivatives.

Tyrosinase Driven‐Intracellular Polymerization of a Porphyrin Derivative Induced Immunogenic Death of Melanoma Cells and Strengthened Photodynamic Therapy

Advanced Science, EarlyView.
This study uses tyrosinase, which is highly expressed in melanoma, to drive porphyrins to polymerize and self‐assemble within tumor cells to form retented microstructures. This process induces immunogenic death and activates immune responses (M1 macrophages, dendritic cells, CD8+T cells), turning “cold” tumors into “hot” tumors.

Carboxyphenolate Coordination Frameworks for High‐Voltage Calcium Storage

Advanced Science, EarlyView.
A hexaanionic carboxyphenolate coordination framework, Ca2‐M‐THBPD (M = Mg, Ca, Ba), exhibits ligand‐centered enolate‐quinonoid redox activity enabling tunable, high‐voltage Ca2+ storage (3.5 V vs Ca2+/Ca) modulated by spectator cations. The amorphous structure accommodates reversible divalent‐ion insertion, contributing to enhanced cycling stability ...
