lycoris radiata/neoplasms

In this study, we investigated the effect of methanolic extract isolated from the root of Lycoris aurea (LA) on the growth of cancer cells and the tube formation activity of endothelial cells. Various cancer cells were treated with LA at doses of 0.3, 1, 3, 10 or 30 μg/ml and LA significantly

Numerous clinically valuable medicines, including anticancer drugs, have been developed from biologically active natural compounds and their structurally related derivatives. This review discusses novel natural compounds with promising biological activities and those with novel chemical structures.

Four new Amaryllidaceae alkaloids, (+)-1-hydroxy-ungeremine (1), (+)-6β-acetyl-8-hydroxy-9-methoxy-crinamine (2), (+)-2-hydroxy-8-demethyl-homolycorine-α-N-oxide (3), (+)-N-methoxylcarbonyl-2-demethyl-isocorydione (4), together with two known compounds, (+)-6β-acetyl-crinamine (5) and

Lycoris radiata (L'Her.) Herb. (L. radiata) was traditionally used as a folk medicine in China for treatment of Alzheimer's disease. However, the specific component responsible for its considerable toxicity remained unclear thus restricting its clinical trials. Narciclasine (NCS) was isolated from

Although crude Amaryllidaceae alkaloids (AAs) extracted from Lycoris radiata are reported to exhibit significant anti-cancer activity, both the specific responsible alkaloid(s) and their targets remain elusive. Screening anti-cancer AAs targeted on topoisomerase I from crude AAs could be very

Some active alkaloids isolated from Lycoris, a bulbous perennial herb, was shown to possess various anti-tumor and anti-inflammatory activities. In this study, we evaluated the in vitro apoptotic effect of ethanol extract from Lycoris radiata (LRE) and further probed the underlying molecular

Phytochemical investigation of the 80% EtOH extract of the bulbs of Lycoris aurea led to the isolation of six new alkaloids, 2-demethyl-isocorydione (1), 8-demethyl-dehydrocrebanine (2), 1-hydroxy-anhydrolycorin-7-one (3), (+)-1,2-dihydroxy-anhydrolycorine N-oxide (4),

Overactivated microglia and persistent neuroinflammation hold an important role in the pathophysiology of neurodegenerative diseases. The extract of Lycoris chejuensis (CJ) and its active compound, 7-deoxy-trans-dihydronarciclasine (named E144), attenuated expressions of

OBJECTIVE Lycoris is aurea agglutinin (LAA) has attracted rising attention due to its remarkable bioactivities. Here, we aimed at investigating its anti-tumor activities. METHODS In vitro methods including MTT, cellular morphology observation, FCM and immunoblotting were performed. In vivo methods

Phytochemical investigation of the ethanol extract of the bulbs of Lycoris caldwellii afforded four new alkaloids, (+)-N-methoxylcarbonyl-nandigerine (1), (+)-N-methoxycarbonyl-lindcarpine (2), (+)-10-O-methylhernovine N-oxide (3), and (+)-3-hydroxy-anhydrolycorine N-oxide (4). Structural

Crude Amaryllidaceae alkaloids (AAs) extracted from Lycoris radiata are reported to exhibit significant anti-cancer activity. However, the specific alkaloids responsible for the pharmacodynamic activity and their targets still remain elusive. In this context, we strived to combine affinity

Lycoris species have been known since long ago as a multi-utility ethnomedicinal herbal in China. It has been reported to exhibit a number of properties such as anticancer, neuroprotective, and antibacterial activities. In the present study, the anticancer efficacy of dichloromethane extracts of

The major active constituents from Amaryllidaceae family were reported to be Amaryllidaceae alkaloids (AAs), which exhibited a wide spectrum of biological activities, such as anti-tumor, anti-viral, and acetyl-cholinesterase-inhibitory activities. In order to better understand their potential as a

Aim. The present study was designed to investigate the cytotoxicity of a panel of 280 Korean medicinal plants belonging to 73 families and 198 species against human CCRF-CEM leukemia cells. Selected phytochemicals were investigated in more detail for their mode of action. Methods. The resazurin
