Labdane-type diterpenoids from the fruits of Vitex trifolia.
Seven new labdane-type diterpenoids, vitextrifolins A-G (1-7), along with eight previously reported analogues, were isolated from the fruits of Vitex trifolia. The structures of 1-7 were elucidated by spectroscopic data interpretation. The isolates were evaluated for their cytotoxicity against four human cancer cell lines (A549, HCT116, HL-60, and ZR-75-30), but all were inactive (IC(50) < 5 μg...
متن کاملAnti-inflammatory constituents from the fruits of Vitex rotundifolia.
Three new diterpenes (7, 15 and 17) and two new neolignans (19 and 20) along with nineteen known compounds have been isolated from the fruits of Vitex rotundifolia. Their structures were elucidated by a combination of 1D and 2D NMR, HRESI-MS, and CD data. All isolates were tested for their inhibitory activities on LPS-induced nitric oxide production in RAW264.7 cells. Of these, compounds 3, 4, ...
متن کاملTen new labdane-type diterpenes from the fruit of Vitex rotundifolia.
Ten new labdane-type diterpenes were isolated from the fruit of Vitex rotundifolia L. (Verbenaceae), along with a known diterpene, vitexilactone. Their chemical structures were determined on the bases of spectroscopic data.

متن کاملLabdane diterpenoids and lignans from Calocedrus macrolepis.
Three new labdane diterpenoids, calomacrins A-C (1-3), and a new diaryl butyrolactone-type lignan, calomacrol A (8), as well as four known labdane diterpenoids and six known lignans, were isolated from the twigs and leaves of Calocedrus macrolepis. Structures of the new compounds were elucidated on the basis of their spectroscopic methods, including 1D and 2D NMR techniques. Compounds 3-14 were...
