Pterocarpans from Derris laxiflora.
Six compounds were isolated from Derris laxiflora Benth., including two new pterocarpans, 7,6'-dihydroxy-3'-methoxypterocarpan (1) and derrispisatin (2), as well as four known ones, lespedezol D, (3), secundiflorol 1 (4), 6a-hydroxymaackiain (5) and pisatin (6). The structures of these compounds were determined by analysis of their spectroscopic data.
متن کاملPterocarpans and flavanones from Sophora flavescens displaying potent neuraminidase inhibition.
Pterocarpans (1-3) and flavanones (4-10) were isolated from Sophora flavescens and screened for their ability to inhibit neuraminidase (an enzyme crucial in the proliferation of the influenza virus). The majority of inhibitors were shown to have IC(50) values of 20 microM or below. Interestingly, pterocarpan 1 emerged as the best inhibitor with an IC(50) of 1.4 microM. We were thus able to prov...
متن کاملAntiplasmodial and Larvicidal Flavonoids from Derris Trifoliata
From the dichloromethane-methanol (1:1) extract of the seed pods of Derris trifoliata, a new flavanone derivative (S)-lupinifolin 4 -́methyl ether was isolated. In addition, the known flavonoids lupinifolin and rotenone were identified. The structures were determined on the basis of spectroscopic evidence. Lupinfolin showed moderate in vitro antiplasmodial activity against the D6 (chloroquine-se...
متن کاملPterocarpans and a Novel Flavanone from Harpalyce brasiliana Roots
A nova “(-)-7,8,3’,4’-tri-hidróxi-8-(3’’,7’’-dimetil-octa-2’’,6’’-dienoil)-flavanona foi isolada a partir do extrato etanólico das raízes de Harpalyce brasiliana, juntamente com os pterocarpanos conhecidos (-)-2-geranil-3-hidróxi-8,9-metilenodioxipterocarpano, harpalicina, medicarpina, maackiaina e as cabenegrinas A-I e A-II. Os metabólitos isolados foram caracterizados com base nos seus dados ...
متن کاملMeranzin hydrate from Muraya paniculata
The coumarin ring system in the title compound, C(15)H(18)O(5) [IUPAC name: 8-(2,3-dihydr-oxy-3-methyl-butyl)-7-meth-oxy-2H-1-benzopyran-2-one], isolated from Muraya paniculata, is planar (r.m.s. deviation 0.017 Å). In the crystal, the two hydr-oxy groups are involved in O-H⋯O hydrogen bonding with adjacent mol-ecules, forming a sheet structure.
