Abstract
Five complex indoline alkaloids, alstolarsines A-E (1-5) possessing two unprecedented carbon skeletons of 6/5/5/7/6/6(5) fused polycyclic systems, were isolated from Alstonia scholaris. Their structures were characterized using various methods including spectroscopic data, ECD spectra, and single-crystal X-ray diffraction. The inhibitory activities of alstolarsines A-D (1-4) on DRAK2 phosphorylation and ATP-citrate lyase were evaluated, but all of them were inactive.
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.
