Abstract
Portimine B was isolated from an extract derived from the dinoflagellate Vulcanodinium rugosum, a known producer of the closely related portimine A. Initial molecular characterization studies of portimine B suggested an open tetrahydrofuranyl ring isomer, contrary to the intact ring moiety found in portimine A. In 2023, the Baran lab synthesized both portimines A and B suggesting that both macrocyclic analogs contained the intact tetrahydrofuranyl ring. In this note, we utilize newly acquired NMR data, the i-HMBC NMR experiment, and advanced density functional theory calculations to define the structural divergence, originating from the presence of a transient hydrate.
期刊介绍:
The Journal of Natural Products invites and publishes papers that make substantial and scholarly contributions to the area of natural products research. Contributions may relate to the chemistry and/or biochemistry of naturally occurring compounds or the biology of living systems from which they are obtained.
Specifically, there may be articles that describe secondary metabolites of microorganisms, including antibiotics and mycotoxins; physiologically active compounds from terrestrial and marine plants and animals; biochemical studies, including biosynthesis and microbiological transformations; fermentation and plant tissue culture; the isolation, structure elucidation, and chemical synthesis of novel compounds from nature; and the pharmacology of compounds of natural origin.
When new compounds are reported, manuscripts describing their biological activity are much preferred.
