- Abstract
The phytochemical investigations of the tuber roots of Asparagus flagellaris led to the isolation of a new alkaloid, schweinfurthiamide (1) and eight known compounds. The structures of the isolated compounds were elucidated using spectroscopic techniques 1D and 2D NMR (1H, 13C, COSY, HMBC, HMQC, HSQC-TOCSY). The absolute configuration of 1 was unambiguously determined using DP4 calculations. Compound 1 showed significant cytotoxicity against MCF-7 (breast cancer), NCI-H460 (lung cancer), and Hela (cervical cancer) cancer cell lines with IC50 values of 1.18 ± 0.02 µM, 2.25 ± 0.19 µM, and 4.23 ± 0.26 µM, respectively and no toxicity against normal human fibroblast (BJ).
