Molecular Editing Reveals a Bilobalide Chemotype that Attenuates Prolyl Endopeptidase (PREP)‐Linked Neuroinflammation

Advanced Science, EarlyView.
Molecular editing of bilobalide uncovers BB56, a PREP‐engaging chemotype with enhanced anti‐inflammatory activity in microglia. Integrated CETSA‐MS, SAR, and pathway analyses link BB56 to attenuation of p38 MAPK/NF‐κB and NLRP3‐associated inflammatory signaling, highlighting bilobalide editing as a strategy for developing neuroinflammation‐modulating ...

Marine sesquiterpene/quinones

, 1995
This chapter discusses marine sesquiterpene/quinones. Although marine sesquiterpene/quinones have predominantly been isolated from sponges, several earliest examples were reported from brown algae, and at least one example has been described from a ...

Essential Oils of Argyreia capitiformis (Poir.) Ooststr. and Argyreia nasirii D.F. Austin: Chemical Analysis and Biological Activities. [PDF]

Chem Biodivers
Essential oils of Argyreia capitiformis and Argyreia nasirii display clearly distinct chemical and biological profiles. A. capitiformis is dominated by sesquiterpene hydrocarbons, particularly (E)‐caryophyllene, and shows cytotoxicity against HepG2, SK‐LU‐1, and MCF‐7 cells. In contrast, A.

Investigations of the Evolved Molecular Basis for Terpenoid Biosynthesis in Marine Sponges

Advanced Science, EarlyView.
Confirming and extending a previous observation in another Bubarida sponge, genomic and functional analyses of A. cavernosa reveal that sponges retain the mevalonate pathway and employ single α‐domain T1TSs and UbiA‐type TSs for terpenoid biosynthesis. The absence of T1TSs clustering with other biosynthetic genes tentatively suggests, based on limited ...

An Effector TaCRVP From Tuta Absoluta Oral Secretion Impairs H2O2‐Mediated Plant Defense by Targeting Tomato SlCAT2

Advanced Science, EarlyView.
The Tuta absoluta salivary effector TaCRVP subverts tomato immunity by hijacking host catalase SlCAT2. Through a sophisticated dual mechanism, TaCRVP simultaneously promotes SlCAT2 tetramerization for activation and blocks its SlAdBiL‐mediated degradation for stabilization.
