Benzylideneacetone (BZA) is a metabolite of gram-negative entomopathogenic bacterium Xenorhabdus nematophila, and it acts as an enzyme inhibitor against phospholipase A2 (PLA2). PLA2 catalyzes a committed biosynthetic step of eicosanoids, which mediate insect immune reactions to infection by microbial pathogens.

A series of conjugates of alpha,beta-unsaturated ketone systems, phenyl-butenone and diaryl-propenones (chalcones), with the tricyclic planar pyrroloquinoline nucleus were synthesised and evaluated for their anticancer properties. The aim was to target DNA by butenone and chalcones, and determine the occurrence

Benzalacetone synthase (BAS), a plant-specific type III polyketide synthase (PKS), catalyzes a one-step decarboxylative condensation of malonyl-CoA and 4-coumaroyl-CoA to produce the diketide benzalacetone. We solved the crystal structures of both the wild-type and chalcone-producing I207L/L208F mutant of Rheum palmatum

The entomopathogenic bacteria Xenorhabdus nematophila and Photorhabdus temperata subsp. temperata suppress insect immune responses by inhibiting the catalytic activity of phospholipase A(2) (PLA(2)), which results in preventing biosynthesis of immune-mediating eicosanoids. This study identified PLA(2) inhibitors derived from culture broths

Twenty-eight compounds related to dehydrozingerone (1), isoeugenol (3), and 2-hydroxychalcone (4) were synthesized and evaluated in vitro against human tumor cell replication. Except for isoeugenol analogues 27-35, most compounds exhibited moderate or strong cytotoxic activity against KB, KB-VCR (a multidrug-resistant
