In this study, twenty-two Amaryllidaceae alkaloids were screened for their anticancer potential. All isolates were evaluated for antiproliferative activities on a panel of 17 human cell types of different tissue origin using WST-1 assay. In addition, we determined the antiproliferative effect with a

Plants from the Amaryllidaceae family have been shown to be a promising source of biologically active natural compounds of which some selected are currently in pre-clinical development. Regardless of interesting pioneer works, little is known about Amaryllidaceae alkaloids that have shown promising

Hostasinine A (1), a benzylphenethylamine alkaloid with an unprecedented skeleton featuring a C-4-C-6 linkage and a nitrone moiety, was isolated from Hosta plantaginea. Its structure was established on the basis of spectroscopic data, and was further confirmed by single-crystal X-ray diffraction.

From the bulbs and leaves of Hymenocallis expansa (Amaryllidaceae), three alkaloid constituents were identified: (+)-tazettine, (+)-hippeastrine, and (-)-haemanthidine. These alkaloids demonstrated significant cytotoxicity when tested against a panel of human and murine tumor cell lines.
