Limonoids from the Branches and Leaves of Aglaia lawii and Their Cytotoxic Activities

Abstract

AbstractThree undescribed limonoids (1–3), named aglaians G–I, and one new natural product azedaralide (4), together with nine known analogues (5–13) were isolated from the branches and leaves of Aglaia lawii by RP C18 column, silica gel column, Sephadex LH‐20 column chromatography and preparative HPLC. The structures of the new compounds were elucidated by IR, HRESIMS, 1D, 2D NMR, electronic circular dichroism (ECD) calculations and X‐ray crystallography diffraction analysis. The results of bioassay showed that the compound 12 exhibited potential inhibitory activity against six human tumor cell lines (MDA‐MB‐231, MCF‐7, Ln‐cap, A549, HeLa and HepG‐2) with IC50 values as 8.0–18.6 μM.
