Angewandte Chemie, Volume 138, Issue 6, 2 February 2026.New push–pull para‐azaquinodimethane derivatives were synthetized through a sustainable protocol. Transient absorption results showed ultrafast intermolecular singlet fission (SF) in film and demonstrated for AsOMe higher triplet energy than for literature SF materials, with intriguing perspectives for photovoltaics toward silicon matched SF.

Cyclic Dipeptides Mediating Quorum Sensing and Their Biological Effects in Hypsizygus Marmoreus
Biomolecules, 2020 A novel quorum sensing (QS) system was discovered in Serratia odorifera, the symbiotic bacterium of Hypsizygus marmoreus. This system uses cyclo(Pro-Phe), cyclo(Pro-Tyr), cyclo(Pro-Val), cyclo(Pro-Leu), cyclo(Tyr-Leu), and cyclo(Tyr-Ile) as autoinducers.

Antimicrobial and Biofilm Inhibiting Diketopiperazines
Current Medicinal Chemistry, 2012 Diketopiperazines are the smallest cyclic peptides known. 90% of Gram-negative bacteria produce diketopiperazines and they have also been isolated from Gram-positive bacteria, fungi and higher organisms. Biosynthesis of cyclodipeptides can be achieved by dedicated nonribosomal peptide synthetases or by a novel type of synthetases named cyclopeptide ...

Diketopiperazines from Alternaria dauci
Journal of the Mexican Chemical Society, 2020 Abstract. Alternaria dauci is the causal agent of Alternaria leaf blight (ALB), a foliar disease of carrot crops (Daucus carota) around the world. In terms of phytotoxic metabolites production, A. dauci has received limited attention. Previous studies carried out on the secondary metabolites involved in the pathogenicity of this fungus have only ...
