New cytotoxic butanolides from Lindera obtusiloba BLUME.
Three new butanolides, 2-(1-methoxy-11-dodecenyl)-penta-2,4-dien-4-olide (1), (2Z,3S,4S)-2-(11-dodecenylidene)-3-hydroxy-4-methylbutano lide (2) and (2E,3R,4R)-2-(11-dodecenylidene)-3-hydroxy-4-methoxy-4-methylbu tanolide (3), were isolated from the stems of Lindera obtusiloba BLUME. Their chemical structures were assigned by spectroscopic evidence. They exhibited cytotoxicity against cultured ...
متن کاملbrotic (+)-Episesamin Isolated from Lindera obtusiloba BLUME
In traditional Korean medicine, an aqueous extract of the plant Lindera obtusiloba has been used for centuries to treat infl ammation, improve blood circulation, and prevent liver damage (Yook, 1989). Recently, we demonstrated antifi brotic, antioxidative, anti-infl ammatory, and antiadipogenic activity of this extract (Rühl et al., 2009; Freise et al., 2009). Freise et al. (2011) documented th...
متن کاملBioactive lignan constituents from the twigs of Lindera glauca.
A bioassay-guided fractionation and chemical investigation of the MeOH extract from the twigs of Lindera glauca (SIEB. et ZUCC.) BLUME resulted in the isolation and identification of six lignans (1-6) including three new lignan derivatives, named linderuca A (1), B (2), and C (3). The structures of the new compounds (1-3) were determined on the basis of spectroscopic analyses, including two dim...
متن کاملAbsolute configuration of antifibrotic (+)-episesamin isolated from Lindera obtusiloba BLUME.
Fractionation of a 70% ethanolic extract from twigs of Lindera obtusiloba BLUME (Japanese spicebush, Tohaku) yielded five fractions of different polarity. The antifibrotic activity within the chloroform phase was best assessed by an in vitro bioassay using rat hepatic stellate cell (HSC) proliferation and their autocrine transforming growth factor beta (TGF-beta) expression as sensitive fibrosi...
متن کاملInhibition of Collagen-Induced Platelet Aggregation by the Secobutanolide Secolincomolide A from Lindera obtusiloba Blume
Atherothrombosis is one of the main underlying cause of cardiovascular diseases. In addition to treating atherothrombosis with antithrombotic agents, there is growing interest in the role of natural food products and biologically active ingredients for the prevention and treatment of cardiovascular diseases. This study aimed to investigate the effect of secolincomolide A (3) isolated from Linde...
