ailanthus esquirolii/抗癌藥

Ailanthione (1), glaucarubinone (2) and a mixture of glaucarubol 15-isovalerate (3) and 13,18-dehydroglaucarubol 15-isovalerate (4) were found to be the compounds responsible for the antitumor and cytotoxic activities of extracts of the root bark of Ailanthus excelsa (Simaroubaceae). The latter

Chaparrinone (1) and 6alpha-tigloyoxychaparrinone (2) were shown to be responsible for the antitumor and cytotoxic activities of the root bark of Ailanthus integrifolia ssp. calycina. The structure of the latter compound was established by analysis of spectral data. Compound 2 exhibited a more

Context The bark of Ailanthus altissima (Mill.) Swingle (Simaroubaceae) is traditionally used to treat ascariasis, diarrhoea, spermatorrhoea, bleeding and gastrointestinal diseases. Objective The objective of this study is to investigate the antitumour activity and mechanism of 2-dihydroailanthone

Ailanthone (AIT) is a quassinoid natural product isolated from the worldwide-distributed plant Ailanthus altissima. The drug displays multiple pharmacological properties, in particular significant antitumor effects against a variety of cancer cell lines in vitro. Potent in vivo activities have been

BACKGROUND We report here the isolation and characterization of a new compound Ailanthus excelsa chloroform extract-1 (AECHL-1) (C(29)H(36)O(10); molecular weight 543.8) from the root bark of Ailanthus excelsa Roxb. The compound possesses anti-cancer activity against a variety of cancer cell lines

Ailanthone is isolated from the bark of Ailanthus altissima (Mill.) Swingle (Simaroubaceae). The mechanism that underlies the activity of ailanthone on MCF-7 cells was investigated by MTT assay. Breast cancer MCF-7 cells were treated with 0.5, 1.0, 2.0, 4.0 and 8.0 µg/ml ailanthone for 24, 48 and 72

The South American Simaba cuspidata Spruce and North Indian Ailanthus grandis Prain were investigated as sources of potentially useful antineoplastic agents. Both of these Simaroubaceae plant species were found to produce 6 alpha-tigloyloxychaparrinone (4a) and the new quassinoid 6

BACKGROUND Biologically active compounds from natural sources are of interest as possible new drugs for different diseases. Over many centuries humans have been mining the bounties of nature for discovering natural products that have been used for the treatment of all human diseases. Ailanthus

Three new quassinoids, ailantinol E (1), ailantinol F (2), and ailantinol G (3), and related compounds were isolated from Ailanthus altissima grown in Taiwan. Their structures were elucidated from spectral evidence. Each new quassinoid was evaluated for its antitumor promoting effects against

Four pairs of racemic phenylpropanoids (1a/1b-4a/4b), including five new compounds (1a/1b, 2a, 3a, and 4a) were obtained from the root barks of Ailanthus altissima (Mill.) Swingle. Their structures were determined by comprehensive spectroscopic analyses. The absolute configurations of the

Ailanthus altissima (AA) has been used in various anticancer prescriptions and showed excellent therapeutic effect. However, there is no report on the method of quality control and the anti-glioblastoma activity. In this study, we used a combinative method approach consisting of chromatographic

Cancer is the second leading cause of death after cardiovascular disease. In 2015, >8.7 million people died worldwide due to cancer, and by 2030 this figure is expected to increase to ~13.1 million. Tumor chemotherapy drugs have specific toxicity and side effects, and patients can also develop

Ailanthone, a natural compound isolated from Chinese herb Ailanthus altissima, has drawn a lot of attention for its antitumor activity. In this study, a simple and sensitive method for determination of ailanthone in rat plasma was developed for the first time, using high-performance liquid
