Amamistatins isolated from Nocardia altamirensis
Four new phenolic siderophores were isolated from the actinomycete Nocardia altamirensis along with the known natural product amamistatin B and a putative biosynthetic shunt product.

The Structural Elucidation of Glycosaminoglycans [PDF]
There is accumulating evidence of the importance of linear polysaccharides in modulating biological phenomena in both the normal and the diseased states. This layer of regulation results from interactions between polysaccharides and other biomolecules, such as proteins, at the cell-extracellular matrix interface.

Elsinopirins A–D, Decalin Polyketides from the Ascomycete Elsinoё pyri
In course of our screening for new secondary metabolites from ecological niche specialized, phytopathogenic fungi, the plant pathogen Elsinoё pyri, strain 2203C, was found to produce four novel compounds (1–4), which were named elsinopirins A–D, in ...

Sampling CASE Application for the Quality Control of Published Natural Product Structures
Structure elucidation with NMR correlation data is dicey, as there is no way to tell how ambiguous the data set is and how reliably it will define a constitution.

Software Tools and Approaches for Compound Identification of LC-MS/MS Data in Metabolomics. [PDF]
The annotation of small molecules remains a major challenge in untargeted mass spectrometry-based metabolomics. We here critically discuss structured elucidation approaches and software that are designed to help during the annotation of unknown compounds.

Tackling the stacking disorder of melon—structure elucidation in a semicrystalline material [PDF]
In this work we tackle the stacking disorder of melon, a layered carbon imide amide polymer with the ideal composition (C6N7(NH)(NH2)). Although its existence has been postulated since 1834 the structure of individual melon layers could only recently be ...
