From data to discovery: leveraging big data in plant natural products biosynthesis research

open access: yesThe Plant Journal, Volume 122, Issue 6, June 2025.
SUMMARY Plant natural products or specialized metabolites play a vital role in drug discovery and development, with many clinically important derivatives such as the anticancer drugs topotecan (derived from the natural alkaloid camptothecin) and etoposide (derived from the natural polyphenol podophyllotoxin).

The genomic and enzymatic basis for iridoid biosynthesis in cat thyme (Teucrium marum)

open access: yesThe Plant Journal, Volume 118, Issue 5, Page 1589-1602, June 2024.
SUMMARY Iridoids are non‐canonical monoterpenoids produced by both insects and plants. An example is the cat‐attracting and insect‐repelling volatile iridoid nepetalactone, produced by Nepeta sp. (catmint) and aphids. Recently, both nepetalactone biosynthetic pathways were elucidated, showing a remarkable convergent evolution. The iridoid, dolichodial,

Total Synthesis of the Myrioneuron Alkaloid (−)‐Schoberine B and Its Enantiomer (+)‐Schoberine B

open access: yesAdvanced Synthesis &Catalysis, Volume 366, Issue 4, Page 948-954, February 20, 2024.
Abstract A dynamic kinetic asymmetric transformation, involving the generation of four stereogenic centers with a well‐defined configuration, occurs in the cyclocondensation of diastereomeric mixtures of 2‐oxocyclohexanepropionic acid racemates 6 with (1S,2R)‐cis‐aminoindanol: two major tetracyclic lactams, 7 a and 7 b, that differ in the configuration

Alkaloids of Lycopodium magellanicum

open access: yesPhytochemistry, 1979
Abstract Six alkaloids have been isolated from Lycopodium magellanicum. These include the known alkaloids lycopodine, acetyldihydrolycopodine, lycodine, N-methyllycodine, acetylfawcettine and a new alkaloid, 5-dehydro-magellanine. The chemical correlation of magellanine and paniculatine and the establishment of their absolute configuration are ...
