Cytotoxic and anti-inflammatory triterpenoids from Toona ciliata.

Toonaciliatavarins A-H (1-8), including three new protolimonoids (1-3), two new tirucallane-type triterpenoids (4 and 5), and three new tetranortriterpenoids (6-8), and 10 known compounds were isolated from the stem barks of Toona ciliata Roem. var. henryi. Their structures were identified on the basis of spectroscopic analysis. The absolute configurations of 2 and 8 were determined by ECD calculation. The new isolates were evaluated for their cytotoxicities using six human cancer cell lines and also for their inhibitory effects on lipopolysaccharide-induced nitric oxide production in RAW264.7 cells. Compounds 4 and 5 showed moderate cytotoxicities, and the protolimonoids (1-3) exhibited marked inhibitory effects on LPS-stimulated NO production.
