Transcriptome Analysis of Derris fordii and Derris elliptica to Identify Potential Genes Involved in Rotenoid Biosynthesis

Phyton
Derris fordii and Derris elliptica belong to the Derris genus of the Fabaceae family, distinguished by their high iso fl avonoid content, particularly rotenoids, which hold signi fi cance in pharmaceuticals and agriculture.

Novel N-containing rotenoid and seco-rotenoid from the root of Derris elliptica

Journal of Asian Natural Products Research, 2009
Two new rotenoids, 2-hydroxy-5-aminorotenonone (1) and elliptoic acid (2), were isolated from the roots of Derris elliptica collected in Guangdong Province, China. Their structures were established by extensive spectral analysis. Compound 1 is the first N-containing rotenoid and compound 2 is the third rotenoid with the cleavage of C(12)-C(12a).

Discovery of Undescribed Flavonoid and Rotenoid Derivatives From the Leaves of Derris trifoliata With Their Cytotoxic Activity

Chemistry and Biodiversity
Phytochemical study on the leaves of Derris trifoliata led to the isolation of five rotenoids (3–7) and 10 flavonoid derivatives (1, 2, 8–15). Three of them, (2S)‐5,7‐dihydroxy‐6‐(2‐hydroxyethyl)‐2‐(4‐hydroxyphenyl)‐8‐(3‐methylbut‐2‐en‐1‐yl)chroman‐4‐one

Rotenoid synthesis via radical cyclisation

Journal of the Chemical Society, Chemical Communications, 1988
The (±)-6aα, 12aα, 12α-chromanochromanol acetate (11; R = Ac), representing the core structure of the insecticidal rotenoid alcohol (2), has been synthesised in six steps from the chromone (4); the cis,cis-stereochemistry is obtained in an intramolecular 6-exo aryl radical addition.

Dimethylchromene rotenoids from Tephrosia candida

Phytochemistry, 1997
Abstract The hexane and ethyl acetate extracts of roots of Tephrosia candida afforded a new rotenoid, 12a-hydroxy-β-toxicarol, together with a series of known ones, identified as: deguelin, α-toxicarol, tephrosin, 6a,12a-dehydrodeguelin, 12a-hydroxy-α-toxicarol, 6a,12a-dehydro-α-toxicarol and 6a,12a-dehydro-β-toxicarol.

Rotenoids from Amorpha canescens roots

Phytochemistry, 1975
Abstract A new rotenoid termed amorpholone has been isolated from a hexane extract of Amorpha canescens roots and identified as 6-hydroxydehydrorotenone by spectroscopic methods. Its structure was conformed by its conversion to rotenonone and by synthesis from rotenone. Also isolated were rotenonone and acetylursolic acid.

Rotenoids and Isoflavones fromSarcolobus globosus

Planta Medica, 2005
Sarcolobus globosus is a medicinal plant growing in mangrove forests in Asia. No constituents from this plant have been reported previously. From the diethyl ether extract of S. globosus a new rotenoid sarcolobin and a new isoflavone sarcolobone, as well as the previously known rotenoids tephrosin, 12aalpha-hydroxydeguelin, 11-hydroxytephrosin, 12a ...

Antiinflammatory activity of rotenoids from Clitoria fairchildiana

Phytotherapy Research, 2002
Five structurally related rotenoids were isolated from the roots of Clitoria fairchildiana. The antiinflammatory activity was investigated using a capillary permeability assay. The protective effect was measured as the inhibition in vascular permeability produced by acetic acid in the peritoneal cavity. The results suggest that for maximum activity the
