BACKGROUND
High consumption of flavonoids has been associated with a decrease risk of cancer. Alfalfa (Medicago sativa) leaves have been widely used in traditional medicine and is currently used as a dietary supplement because of their high nutrient content. We previously reported the cytotoxic
Tumor necrosis factor α-related apoptosis-inducing ligand (TRAIL) is a promising anticancer agent with cancer cell-selective cell death inducing effect. However, the major limitation in the usage of TRAIL as a chemotherapeutic agent is the development of TRAIL resistance in many cancer types
Agrobacterium tumefaciens-induced plant tumors accumulate considerable concentrations of free auxin. To determine possible mechanisms by which high auxin concentrations are maintained, we examined the pattern of auxin and flavonoid distribution in plant tumors. Tumors were induced in transformants
Alfalfa (Medicago sativa) has been used to cure a wide variety of ailments. However, only a few studies have reported its anticancer effects. In this study, extracts were obtained from alfalfa leaves and their cytotoxic effects were assessed on several sensitive and multidrug-resistant tumor cells
The promising biological role of the ubiquitin proteasome pathway (UPP) in cancer therapy has recently emerged. Inhibition of proteasome has been proposed as a new therapeutic target for treatment of cancer. Bioassay-guided fractionation of a MeOH extract of the stems of Spatholobus suberectus
Pterocarpans, a special kind of isoflavonoids possessing two contiguous benzofuran and benzopyran rings, have been reported as possessing several biological activities. In order to isolate and identify the active principles possibly responsible for the stronger activity of the EtOH extract from
A new phenolic compound, 1-(3-hydroxy-4-methoxyphenyl)-3-(2,4-dihydroxy-5-methoxyphenyl) propan-1-ol, named as millettinol (1), along with six known compounds, medicarpin (2), 4-hydroxy-3-methoxy-8,9-methylenedioxypterocarpan (3), 5,4'-dihydroxy-7,8-dimethoxyisoflavone (4), physcion (5),
Two new isoflavonoids, 7-hydroxy-6,4'-dimethoxy-isoflavonequinone (1) and 2'-hydroxy-6,4',6' ',4' ''-tetramethoxy-[7-O-7' ']-bisisoflavone (2), and seven other known flavonoids, 3-hydroxy-9-methoxypterocarpan (medicarpin), 3,10-dihydroxy-9-methoxypterocarpan, 3,9-dimethoxypterocarpan
An extract from Spatholobus suberectus (S. suberectus) Dunn has been reported to show potent antimutagenic effects against N-alkyl-N-nitrosoureas in umu screening. The aim of this study was to identify the antimutagenic components
