Four new compounds (1-4) were isolated along with 16 known compounds from whole plants of Peperomia duclouxii. The new structures were elucidated as 4-hydroxy-2-[(3,4-methylenedioxyphenyl)nonanoyl]cyclohexane-1,3-dione (1), 4-hydroxy-2-[(3,4-methylenedioxyphenyl)undecanoyl]cyclohexane-1,3-dione (2), 4-hydroxy-2-[(3,4-methylenedioxyphenyl)tridecanoyl]cyclohexane-1,3-dione (3), and 2-[(3,4-methylenedioxyphenyl)dodecyl]-4-hydroxy-2,3,4,6,7,8-hexahydro-2H-1-benzopyran-5-one (4), by analysis of… 
Antiangiogenic Polyketides from Peperomia dindygulensis Miq
Two new polyketides are isolated from the whole plant of Peperomia dindygulensis Miq and their structures were elucidated by spectroscopic methods, including 2D-NMR techniques.
New long-chain aliphatic compounds from Peperomia dindygulensis
Three long-chain aliphatic compounds, including one new polyketide derivative, dindygulerione C, were isolated from the whole plant of the Chinese anticancer folk medicine Peperomia d Indygulensis Miq (Piperaceae).
Antifungal and cytotoxic 2-acylcyclohexane-1,3-diones from Peperomia alata and P. trineura.
Bioactivity-guided fractionation of the separate CH2Cl2 extracts from the aerial parts of Peperomia alata and P. trineura yielded seven polyketides that were evaluated for antifungal activity against Cladosporium cladosporioides and C. sphaeospermum and for cytotoxicity against the K562 and Nalm-6 leukemia cell lines.
Efficient Syntheses of New 2,2′-Disubstituted-2,3-dihydrofuran Derivatives and Natural Polyketide Analogues
Abstract Efficient syntheses of new 2,2′-disubstituted-2,3-dihydrofuran(5H)-4-one,spiro{benzofuran-2,2′-bicyclo[2.2.1]heptan}-4(5H)-one derivatives, and natural polyketide analogues have been
Anti-inflammatory and Quinone Reductase-Inducing Compounds from Beilschmiedia mannii.
The fruits of Beilschmiedia mannii, whose dichloromethane extract showed cancer chemopreventive properties, were selected and bioactivity-guided fractionation resulted in the isolation and identification of two γ-pyrones, including desmethoxydihydromethysticin found in a natural source for the first time, as well as five known alkamides.
