UV and IR spectroscopy of singly protonated DIYETDYYR, a tryptic peptide from the regulatory loop of insulin receptor

Bulletin of the Korean Chemical Society, EarlyView.
The structure of singly protonated DIYETDYYR, which is a tryptic peptide in the regulatory loop of the insulin receptor, was determined by cryogenic ion spectroscopy. Abstract DIYETDYYR is a tryptic peptide from the regulatory loop of insulin receptor, which has the three tyrosine residues need for activation of the protein.

Chemical Composition, Antioxidant, and Antibacterial Activities of Mezilaurus duckei (Lauraceae)

Chemistry &Biodiversity, EarlyView.
ABSTRACT Mezilaurus duckei, a Brazilian endemic tree species found exclusively in the Amazon Rainforest, is primarily exploited for timber in construction. Due to its endangered status, this study aimed to investigate the chemical profile and biological properties of the ethanolic extract and its phases derived from M. duckei leaves. Chemical profiling

Co‐cultivation and Medium Optimization: A Strategy for Discovering Fungal‐derived Protease Inhibitors

Chemistry &Biodiversity, EarlyView.
ABSTRACT The fungi Fusarium guttiforme and Phytophthora palmivora were cultivated in four different media (Potato Dextrose Agar, Czapek, rice, and ISP2) and co‐cultured to stimulate fungal interactions and enhance secondary metabolite production. Promising extracts were fractionated, yielding compounds such as the iron complex of fusaric acid (1 ...

Impact of Species, Growth Conditions, and Plant Processing on the Phytochemistry and Antimicrobial Activity of Agrimonia Extracts

Chemistry &Biodiversity, EarlyView.
Agrimony is a medicinal herb known for its content of polyphenols and beneficial bioactivity, both of which can be strongly influenced by cultivation and processing. This study reveals that agrimony plant structures, species, and postharvest processing are the main drivers of observed variability in both phytochemical composition and antimicrobial ...
