deguelin/デリス属

Deguelin is a natural compound of the flavonoid family products isolated from Derris trifoliata Lour. or Mundulea sericea (Leguminosae). It exhibited significant anti-tumorigenesis and anti-proliferative activity in various types of cancer both in vitro and in vivo. Deguelin induced cell apoptosis

From the acetone extract of the roots of Derris trifoliata an isoflavonoid derivative, named 7a-O-methyldeguelol, a modified rotenoid with an open ring-C, representing a new sub-class of isoflavonoids (the sub-class is here named as rotenoloid), was isolated and characterised. In addition, the known

OBJECTIVE To study the brine shrimp lethal activities of the roots and stems from Derris trifoliata. METHODS The biological activity of the athyl acetate extract was tested by the 2nd-instar of Artemia franciscana by the method of Silica gel column chromatography, Sephadex LH-20 column

A new flavanone, 4',5,7-trihydroxy-6,8-di-(2-hydroxy-3-methylbut-3-enyl)- flavanone, was isolated from the aerial parts of Derris trifoliate, together with eleven known compounds: rotenone, tephrosin, 12a-hydroxyrotenone, deguelin, 6a,12a-dehydro-rotenone, dehydrodeguelin, 7a-O-methyldeguelol,

Using the natural rotenoids rotenone, amorphigenin, deguelin, rotenonic acid, dalpanol and munduserone as examples, their phytochemical biosynthesis has been examined in Derris elliptica, Amorpha fruticosa and Tephrosia vogelii. The rotenoids are advanced isoflavonoids, and construction of their

Rotenoids are the active ingredients of some botanical insecticides and prospective candidates as anticancer agents. The proper isolation and determination of rotenoids in plants is of great importance for their further research and development. However, the HPLC method available for this purpose

A study of the chemical constituents of the stems of Derris trifoliata Lour. (Leguminosae) led to the isolation and identification of one new rotenoid, 6aalpha,12aalpha-12a-hydroxyelliptone ( 3), together with five other known rotenoids. In a search for novel cancer chemopreventive agents

Nine rotenoids were isolated from the hexane and dichloromethane extracts of Derris trifoliata stems and were tested for nitric oxide (NO) inhibitory activity using RAW264.7 cells. The result indicated that 12a-hydroxyrotenone (7) possessed very potent NO inhibitory activity with an IC(50) value of

Two rotenoids (rotenone and deguelin) were successfully isolated and purified from the roots of Derris by high-speed counter-current chromatography (HSCCC) with a two-phase solvent system composed of n-hexane-ethylacetate-methanol-water (7: 0. 25:5:3, v/v/v/v) on a preparative scale. The lower phase

A glass capillary column coated with PS-086 (15% phenyl-80% methylpolysiloxane, 15 m x 0.30-mm i.d., 0.1-microm film thickness) is used to analyze extracts from Lonchocarpus urucu (Derris urucu). Several secondary metabolites (8 flavonoids, 10 rotenoids) are characterized without derivatization, and
