The structure of janthinolide A was established using MS spectrometry in combination with 1D and 2D NMR data (molecular formula C23H32N2O7), however it was later amended with the use of Structure Elucidator Suite combined with DFT based NMR chemical shift prediction.

Sonnenschein et al. investigated the fungus Pseudoalteromonas piscicida S2040 to yield pseudochelin A - a new siderophore containing a 4,5-dihydroimidazole moiety. This challenging structure containing eight heteroatoms (three atoms of nitrogen and fife atoms of oxygen) was elucidated by Structure Elucidator fully automatically in 1.5 seconds.

Get a deeper insight into how computer assisted structure elucidation can help you assign structures to data with confidence. Alexei shares his decades of experience in structure elucidation and presents technology solutions (CASE and DFT) to prevent misassignments as illustrated by natural product structure revisions published in recent years.

Sesquiterpenoids are a class of compounds known to have complex structures, and due to the wide variability of these compounds, it is often challenging to determine the exact structure. Here we discuss the incorrect determination of the structure of Nordine, and later correction; as well as the elucidation of the correct structure using CASE.

Xiao-Wei and coworkers identified a new aspergillamide C (molecular formula C28H34N4O4). To elucidate the structure of this compound, 1D NMR, HSQC, HMBC, COSY and NOESY data were entered into Structure Elucidator Suite.
