elephantopus mollis/抗癌藥

BACKGROUND Deoxyelephantopin (DOE) is a natural bioactive sesquiterpene lactone from Elephantopus scaber, a traditionally relevant herb in Chinese and Indian medicine. It has shown promising anticancer effects against a broad spectrum of cancers. METHODS We examined the effect of DOE on growth,

OBJECTIVE To evaluate antitumor activity of sesquiterpene lactones (scabertopin (ES-2), isoscabertopin (ES-3), deoxyelephantopin (ES-4), isodeoxyelephantopin (ES-5)) isolated from Elephantopus scaber L. in vitro and in vivo. METHODS SMMC-7721, Caco-2 and HeLa cell lines were treated with ES-2,3,4,5.

Isolated from Elephantopus scaber L., a Chinese medicinal herb that is widely used to prevent and treat cancers in China, isodeoxyelephantopin (ESI) exerted antitumor effects on several cancer cells. However, its antitumor mechanism is still not clear. In this study, we found that ESI could induce

Cancer is the 2nd leading cause of death worldwide. The development of drugs to target only one specific signaling pathway has limited therapeutic success. Developing chemotherapeutics to target multiple signaling pathways has emerged as a new prototype for cancer treatment. Deoxyelephantopin (DET)

The ethanolic extract of Elephantopus mollis yielded three novel cytotoxic antitumor germacranolides, molephantin, molephantinin, and phantomolin. The extract also yielded three inactive known triterpenes, beta-amyrin acetate, lupeol acetate, and epifriedelanol, as well as stigmasterol. The

Lupeol is a triterpenoid, present in most of the medicinally effective plants and possess a wide range of biological activity against human diseases. The present study aims at evaluating the anticancer potentials of lupeol, isolated from the leaves of Elephantopus scaber L. and thereby explores its

OBJECTIVE Deoxyelephantopin, a sesquiterpene lactone from Elephantopus scaber, showed inhibition of the growth of various tumor cells in vitro. In the present study, we investigated the cytotoxicity and apoptosis-inducing capacity of deoxyelephantopin on lung adenocarcinoma (A549) cells. METHODS The

Nudaphantin, a new cytotoxic germacranolide, and the known elephantopin were isolated from Elephantopus nudatus, and their structures elucidated on the basis of physicochemical data, spectral evidence, and direct comparison with authentic samples.

7.12-dimethylbenz (α)anthracene (DMBA) is a carcinogenic compound. It is metabolized in the liver by cytochrome P450 enzyme into 7.12-dimethylbenz (α) anthracene-3.4-diol-1.2-epoxide (DMBA-DE) which is more reactive and can damage the hepatic cell. Furthermore, DMBA also can damage the kidneys and

The active principle responsible for the significant inhibitory activity against the Walker 256 carcinosarcoma (ascites) in rats, isolated from the chloroform extract of the whole plant of Elephantopus carolinianus Willd., was characterized as deoxyelephantopin, a sesquiterpene lactone.

The structures and absolute stereochemistries of tomenphantins A (1) and B (2), cytotoxic germacranolides isolated from Elephantopus tomentosus, are reported herein. 1H and 13C NMR spectroscopic data, chemical transformation, and single-crystal X-ray analysis were used in these determinations.

Isodeoxyelephantopin (IDET) has been identified as an anti-tumor natural constituent whose anti-tumor activity and mechanism have been widely investigated. Since the occurrence and development of cancer usually accompany with inflammation, and tumor signaling shares many components with inflammation

Isodeoxyelephantopin (ESI), isolated from Elephantopus scaber L. has been reported to exert anticancer effects. In this study, we aimed to investigate whether and how cancer cells exert protective responses against ESI treatment. Confocal fluorescence microscopy showed that ESI significantly induced

In order to look for lower toxic and strongly active compounds, the structure of sesquiterpene lactones from Elephantopus scaber was modified. Deoxyelephantopin and scabertopin were isolated from the whole plant of Elephantopus scaber and hydrogenated and epoxidated. Five sesquiterpenoide
