Pancratistatin (PST), a natural compound obtained from the Hawaiian spider lily, is known to be specific and selective in inducing apoptosis in multiple cancer cell lines while sparing noncancerous cells and cell lines. Here we report the ability of PST to induce apoptosis specifically in human
Sensitization of human melanoma cells by tamoxifen to apoptosis induction by pancratistatin, a nongenotoxic natural compound.

The objective of this study was to determine the efficacy of the natural compound pancratistatin (PST), isolated from the Hymenocallis littoralis, in human melanoma cells. Melanoma is an aggressive form of skin cancer that is commonly fatal if not diagnosed in its early stage of development.

By cloning Hymenocallis littoralis, a practical biosynthetic procedure was developed for producing pancratistatin [1]. The plant tissue culture-->greenhouse-->field production sequence was successively utilized for increasing an original 1.5 kg of wild H. littoralis bulbs to some 60,000 bulbs at
Pancratistatin induces apoptosis in clinical leukemia samples with minimal effect on non-cancerous peripheral blood mononuclear cells.

BACKGROUND
Pancratistatin, a natural compound extracted from Hymenocallis littoralis, can selectively induce apoptosis in several cancer cell lines. In this ex vivo study, we evaluated the effect of pancratistatin on peripheral blood mononuclear cells obtained from 15 leukemia patients prior to
Pancratistatin Inhibits the Growth of Colorectal Cancer Cells by Inducing Apoptosis, Autophagy, and G2/M Cell Cycle Arrest.

BACKGROUND Worldwide, colorectal cancer is ranked as the third most prevalent cancer. The natural compound, pancratistatin, extracted from the spider lily, has previously been shown to target apoptosis in cancer cells lines. This study aimed to investigate the effects of pancratistatin in human
Pancratistatin: a natural anti-cancer compound that targets mitochondria specifically in cancer cells to induce apoptosis.

The major hurdle in the fight against cancer is the non-specific nature of current treatments. The search for specific drugs that are non-cytotoxic to normal cells and can effectively target cancer cells has lead some researchers to investigate the potential anti-cancer activity of natural
A novel synthetic C-1 analogue of 7-deoxypancratistatin induces apoptosis in p53 positive and negative human colorectal cancer cells by targeting the mitochondria: enhancement of activity by tamoxifen.

The natural compound pancratistatin (PST), isolated from the Hymenocallis littoralis plant, specifically induces apoptosis in many cancer cell lines. Unlike many other chemotherapeutics, PST is not genotoxic and has minimal adverse effects on non-cancerous cells. However, its availability for
Effects of atmospheric CO2 enrichment on the growth and development of Hymenocallis littoralis (Amaryllidaceae) and the concentrations of several antineoplastic and antiviral constituents of its bulbs.

Two 2-yr crops of tropical spider lily (Hymenocallis littoralis) plants were grown in field soil in clear-plastic-wall open-top enclosures in the Sonoran Desert environment of central Arizona. Half of the plants were exposed to ambient air of 400 ppm atmospheric CO(2) concentration and half of them

The bulbs of Hymenocallis littoralis, collected in Hawaii and horticulturally grown in Arizona, and bulbs of Hymenocallis caribaea and Hymenocallis latifolia, collected in Singapore, were found to contain a cytotoxic, isocarbostyril-type biosynthetic product, 7-deoxy-trans-dihydronarciclasine [2].

Seven species (and one cultivated variety) of Hymenocallis (Amaryllidaceae) and the related Pancratium maritima, representing a broad geographical selection, were investigated as sources of pancratistatin [1] now undergoing preclinical development as an anticancer agent. Pancratistatin [1] was found
Isolation and structural modification of 7-deoxynarciclasine and 7-deoxy-trans-dihydronarciclasine.

As an extension of structure-activity relationship studies of pancratistatin (1), various techniques were first evaluated for separating the mixtures of 7-deoxynarciclasine (2b) and 7-deoxy-trans-dihydronarciclasine (3a) isolated from Hymenocallis littoralis. An efficient solution for that otherwise
