Two new furanocoumarins, lucidafuranocoumarins B (1) and C (2), were isolated from the twigs of Feroniella lucida, together with five known compounds (3–7). The structures of these compounds were identified on the basis of extensive spectroscopic methods. The absolute configurations of lucidafuranocoumarin C at C-2″ and C-5″ were established as R- and S-configurations, respectively, by applying Mosher's method. Some isolates were also evaluated for their cytotoxicity against KB, MCF-7 and NCI-H187 cell lines. 相似文献

A new hydroperoxyquinolone alkaloid, glycopentaphyllone (1), along with nine compounds (2–10), was isolated from the fruits of Glycosmis pentaphylla. Their structures were elucidated on the basis of spectroscopic methods. The absolute configuration of glycopentaphyllone at C-2′ was established as S-configuration by applying Mosher's method. In addition, the completed assignments of 13C NMR as well as 2D NMR spectral data of compound 5 were reported herein for the first time. Also, all isolates were evaluated for antibacterial activity against Escherichia coli TISTR 780, Salmonella typhimurium TISTR 292, Staphylococcus aureus TISTR 1466, and Methicillin-resistant S. aureus SK1. 相似文献

A phytochemical investigation of the twigs of Glycosmis cochinchinensis led to the isolation of two new alkaloids, glycosmisacridone (1) and glycosmisindole (2), together with eight known compounds (3–10). Their structures were elucidated by intensive analysis of their spectroscopic data. Compound 9 exhibited moderate antibacterial activity against methicillin-resistant Staphylococcus aureus SK1with an MIC value of 16 μg/mL. 相似文献
