A New Languidulane Diterpenoid from Salvia mexicana var. mexicana

Molecules, 2011
From the aerial parts of Salvia mexicana var. mexicana, two C-10 epimers (α and β) of salvimexicanolide were isolated. Our interpretation of the data, especially the 13C NMR, led us to conclude that the previously described 13C-NMR spectrum of the α ...

Biosynthetic Pathways and Regulation of Antibacterial Compounds From Endophytic Fungi: From Chemistry to Genomics and Biotechnology

Chemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Endophytic fungi encode abundant cryptic biosynthetic gene clusters that remain largely silent under conventional cultivation. This review highlights how genome mining, multi‐omics, and cluster activation strategies bridge the BGC‐to‐metabolite gap, enabling the discovery of structurally diverse antibacterial natural products with activity against ...

Meroterpenoids Produced by Fungi: Occurrence, Structural Diversity, and Biological Activity (An Update: February 2020 to December 2025)

Chemistry &Biodiversity, Volume 23, Issue 11, November 2026.
This review firstly summarizes the update of meroterpenoids from February 2020 to December 2025 by applying a new classification method based on twelve key non‐terpene precursors. ABSTRACT Meroterpenoids are a class of hybrid natural products, biosynthesized from terpenoid fragments and non‐terpenoid precursors, exhibiting a wide range of biological ...
