The Structures and Stereochemistry of Cytotoxic Sesquiterpene Quinones from Dactylospongia elegans.
Natural Products from Antarctic Colonial Ascidians of the Genera Aplidium and Synoicum: Variability and Defensive Role
A series of colonial Antarctic ascidians from deep-water collections belonging to the genera Aplidium and Synoicum are analyzed to evaluate the incidence of organic deterrents and their variability and the possible origin of both types of metabolites is discussed.
Structural characterization of vanchrobactin, a new catechol siderophore produced by the fish pathogen Vibrio anguillarum serotype O2
Structure and Biosynthetic Assembly of Piscibactin, a Siderophore from Photobacterium damselae subsp. piscicida, Predicted from Genome Analysis
An NRPS-mediated mechanism similar to that for yersiniabactin was suggested by protein sequence comparisons and the results obtained in the structural and functional characterization of piscibactin enabled the proposal of a biosynthetic pathway.
Signaling the induction of sporulation involves the interaction of two secondary metabolites in Aspergillus nidulans.

This study has shown that mutants that are defective in the fluG gene fail to undergo sporulation because they lack an endogenous diffusible factor that purportedly accumulates on aerial hyphae, thus signaling the initiation of development can be reversed by adding culture extracts from a wild-type strain onto a mutant colony.
Evaluation of the effects of several zoanthamine-type alkaloids on the aggregation of human platelets.
A Transmissible Plasmid-Borne Pathogenicity Island Confers Piscibactin Biosynthesis in the Fish Pathogen Photobacterium damselae subsp. piscicida
The importance of pPHDP70, with its capacity for piscibactin-mediated iron acquisition, in the virulence of P. damselae subsp.

Comparison of NMR spectral data strongly suggests that pyrostatins A and B are identical to 5-hydroxyectoine and ectoine, respectively.
