New Alkaloids and Anti-inflammatory Constituents from the Leaves of Antidesma ghaesembilla

Phan Van Kiem et al. Nat Prod Commun. 2017 Jan.

Abstract

Using various chromatographic methods, two new alkaloids, antidesoic acids A (1) and B (2) along with fourteen known compounds (3-16) were isolated from the leaves of Antidesma ghaesembilla Gaertn. Their chemical structures were elucidated by physical and chemical methods. All the isolated compounds were evaluated for their inhibitory activity on LPS-stimulated nitric oxide (NO) production in BV2 cells and RAW 264.7 macrophages. Bisflavone 8 significantly inhibited LPS- stimulated NO production in BV2 cells and RAW 264.7 macrophages with IC₅₀ values of 5.4 and 8.0 μM, respectively. Compounds 1-3, 7, 10, 12, 14, and 16 showed moderate inhibitory activities with IC₅₀ values ranging from 11.7 to 77.4 μM.
