Abstract
Prorocentrin-5 (1) was isolated from the benthic marine dinoflagellate Prorocentrum lima. A combination of NMR spectroscopy, quantum chemical calculations, and chemical reactions was then employed to elucidate its molecular structure, including the configurations of all stereogenic centers. In cytotoxicity assays, prorocentin-5 exhibited potent activity against the HCT-116 and Neuro2a cell lines, with IC50 values of 4.4 and 2.8 μM, respectively. Furthermore, 1 increased the apoptotic cell population and induced cell cycle arrest, leading to the accumulation of cells in the S or G2/M phase and an accompanying decrease in the G0/G1 phase in HCT-116, Neuro2a, and HepG2 cells.
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.
