Molecular Networking‐Guided Discovery of Kyonggic Acids in Massilia spp.

European Journal of Organic Chemistry, Volume 27, Issue 17, May 3, 2024.
The metabolomes of six Massilia strains were analyzed using a molecular‐networking guided approach, revealing interconnections among metabolites. A closer inspection of the most promising strains led to the discovery of novel N‐acylated amino acids, termed kyonggic acids.

Genomic‐wide identification and expression analysis of AP2/ERF transcription factors in Zanthoxylum armatum reveals the candidate genes for the biosynthesis of terpenoids

The Plant Genome, Volume 17, Issue 1, March 2024.
Abstract Terpenoids are the main active components in the Zanthoxylum armatum leaves, which have extensive medicinal value. The Z. armatum leaf is the main by‐product in the Z. armatum industry. However, the transcription factors involved in the biosynthesis of terpenoids are rarely reported.

Circular dichroism studies of bisindole Vinca alkaloids

Tetrahedron, 1998
Abstract The analysis of a series of seventeen vinblastine analogs by circular dichroism is described. Exciton coupling of the indole and indoline chromophores of these compounds provides a general, non-empirical method for the assignment of the C16′ configuration with the bioactive C16′-S and the inactive C16′-R analogs giving rise, respectively, to
