Schweinfurthiamide, a new alkaloid isolated from the tuber roots of < em > Asparagus flagellaris < /em > Baker (Liliaceae)

Nat Prod Res. 2023 Sep 18:1-7. doi: 10.1080/14786419.2023.2257358. Online ahead of print.ABSTRACTThe 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).PMID:37722707 | DOI:10.1080/14786419.2023.2257358
