We describe a case with chronic bronchial foreign body presenting with recurrent hemoptysis mimicking a peripheral lung tumor, and the outcome of surgical resection. A 61-year-old female with recurrent hemoptysis had a peripheral nodule in the right lower lobe. A right bronchial arteriogram showed
Three new (1-3) and several known (4-6) steroids were isolated from the leaves of Chinese Melia azedarach. The structures of the new compounds were elucidated by means of spectroscopic methods including 2D NMR techniques and mass spectrometry to be
Ten new triterpenoids, named meliasenins I-R (1-10), one new steroid (11), and 11 related known compounds (12-22) were isolated from fruits of Melia toosendan. The structures of the new compounds were established on the basis of spectroscopic methods, including 2D NMR techniques and mass
12-O-Acetylazedarachin B (1), isolated from the fruit extract of Melia azedarach, exhibited potent cytotoxicity against leukemia (HL-60) (IC(50) 0.016 µM) and stomach (AZ521) (IC(50) 0.035 µM) cancer cell lines. Upon assessing the apoptosis-inducing activity in HL-60 cells, compound 1 exhibited
Colorectal cancer is one of the leading causes of death in the world. Plant-derived products have proven to be valuable sources for discovery and development of unique anticancer drugs. In this study, the inhibitory effects of ethanolic extract of Melia toosendan fruit (EMTF), a traditional medicine
In this study, the 4-week oral toxicity and anti-cancer activity of the hexane layer of Melia azedarach L. var. japonica Makino's bark extract were investigated. We carried out a hollow fiber (HF) assay and 28- day repeated toxicity study to confirm the anti-cancer effect and safety of the hexane
The limonoid compound (28-deacetyl sendanin) isolated from the fruit of Melia toosendan SIEB. et ZUCC. was evaluated on anticancer activity. According to a standard in vitro cytotoxicity assay, eight human cancer cell lines and SRB assay were introduced for present evaluation. As a positive
Medicinal plants can be candidate as a common alternative for cancer treatment according to natural landscaping and native plants in each country. The aim of this study was the evaluations of cytotoxicity, apoptosis, and cell cycle arrest induction by using seven leaves extracts of Catharanthus
Melia azedarach L. is used widely in traditional medicine for local or systemic ailments. Although studies exist on phytochemicals and potencies of Chinese and Indian cultivars of Melia, the present study investigated in vitro antioxidant properties of Melia wild type and
This work examines the antitumor activity of an isomeric mixture (1), composed of the limonoids meliartenin and its interchangeable isomer 12-hydroxyamoorastatin. The results obtained showed that 1 displayed outstanding cytotoxic activity against CCRF-CEM, K562, A549 and HCT116 cells, with a highly
Animal models play a key role in identifying treatments for various types of cancer, including lung cancer. The aim of the present study was to develop a new animal model for lung cancer induction using tree shrews from the Yunnan region in China. Tree shrews are suitable for a full simulation of
Toosendanin (TSN) is a triterpenoid purified from the medicinal herb Melia toosendan Sieb. et Zucc and has been used as an insecticide for decades. Recent studies have attracted increasing interest of TSN due to its novel anti-cancer effect in diverse cancer models. The broad spectrum anti-cancer
Toosendanin (TSN) is a tetracyclic triterpenoid extracted from Melia toosendan Sieb, et Zucc, which primarily grows in specific areas of China. Although toosendanin (TSN) exerts antitumoral effects on various human cancer cells, its influence on gastric cancer (GC) is remains to be elucidated.
Toosendanin, a triterpenoid derivative isolated from the barks of Melia toosendan Sieb et Zucc, has been used as an anthelmintic vermifuge against ascaris for more than fifty years in China. In the present study, we investigated the growth inhibition and apoptosis-induced effect of toosendanin on
Adriamycin (ADM) is a commonly used drug in clinical breast cancer treatment. However, some breast cancer types or breast cancers subjected to repeated ADM exposure develop strong resistance to ADM thus limiting its clinical efficacy. In this study, we found for the first time that toosendanin
