Abstract (Summary)

Natural products from plants have been an important source in drug discovery throughout human history, especially in anticancer drug development. The New Jersey Pine Barrens (NJ pinelands) is a vast wild ecosystem from which little chemical or bioactivity exploration of the plants has been done. In our continuing search for naturally-occurring compounds with interesting biological activities, bioassay-guided fractionation of Leiophyllum buxifolium (sand myrtle) collected from the NJ pinelands, led to the isolation of a new C-methylisoflavone, isosideroxylin. This new compound displayed a selective antiproliferative effect against MDA-MB-231 cells, while showing weak inhibition against the MCF-7 cell line and no inhibition against the normal fibroblast cell line. To prepare for the SAR study and search for more potent analogs, a proof of concept study of the total synthetic route of isosideroxylin starting from phloroglucinol was developed.
