Phragmalin-Type Limonoids from the Fruits of Chukrasia tabularis and Their Anti-Inflammatory Activity

Phytochemical investigation on the fruits of C. tabularis led to the isolation of five new phragmalin-type limonoids (1–5) and four known ones (6–9). The structures of the new compounds 1–5, named chuktabamalins A–E, were elucidated via spectroscopic techniques (HRESIMS, 1D and 2D NMR) and were comp...

Sumario:Phytochemical investigation on the fruits of C. tabularis led to the isolation of five new phragmalin-type limonoids (1–5) and four known ones (6–9). The structures of the new compounds 1–5, named chuktabamalins A–E, were elucidated via spectroscopic techniques (HRESIMS, 1D and 2D NMR) and were comparable with the literature data of known compounds. In addition, new compounds were evaluated for in vitro anti-inflammatory activity. Compounds 1, 2, 3 and 5 showed moderate anti-inflammatory activity with IC(50) values of 21.72 ± 2.79, 23.29 ± 1.00, 47.08 ± 3.47 and 66.67 ± 2.89 μM, respectively.
