Angewandte Chemie, Volume 134, Issue 26, June 27, 2022., 2022 Dynamic conversions of single molecules can be monitored at doubly cucurbit[7]uril‐functionalized supramolecular junctions. Through this intermolecular recognition tunneling technique, the molecular conductance of different analytes and analyte mixtures can be finger‐printed in dependence on pH and competitive salts, showcasing the first examples of ...

Chemistry &Biodiversity, Volume 20, Issue 12, December 2023., 2023 Abstract Genus Corydalis is a rich source of isoquinoline alkaloids reported to having potential bioactivities. Corydalis chaerophylla collected from Nepal at an altitude of 2400–4800 m was extracted using hexane, methanol and chloroform as solvents. The resulting hexane, methanol and chloroform extracts were subjected to LC–DAD‐MSn analysis to yield ...

Advances in the natural α‐glucosidase inhibitors
eFood, Volume 4, Issue 5, October 2023., 2023 Natural products are a great source for the development of new α‐glucosidase (AG) inhibitory drug candidates. We aim to summarize advances in natural AG inhibitors according to their secondary metabolite groups in the last decade. Their mechanisms of action and structure–activity relationships will especially be discussed.

Sanguinarine reductase, a key enzyme of benzophenanthridine detoxification [PDF]
Plant, Cell & Environment, 2005 ABSTRACTCultured cells of Eschscholzia californica respond to a yeast glycoprotein elicitor by producing benzophenanthridine alkaloids, which are excreted into the cell wall and the outer medium. These compounds, preferentially sanguinarine, are efficient phytoalexins because of their ability to intercalate double‐stranded DNA (dsDNA), penetrate ...

Sanguinarine synergistically potentiates aminoglycoside‐mediated bacterial killing
Microbial Biotechnology, Volume 15, Issue 7, Page 2055-2070, July 2022., 2022 Aminoglycosides primarily interact with the bacterial ribosomes and result in protein misfolding and ROS production. Insertion of abnormal proteins into the cell membrane increases the membrane permeability and leads to enhanced uptake of sanguinarine.
