摘要
Two new beta-carboline alkaloids, anemonilins A and B (1-2), and two known beta-carboline alkaloids, flazine (3) and 4-(9H-beta-carbolin-l-yl)-4-oxo-butyric acid (4), were isolated from the roots of Anemone altaica. The structures of the isolated compounds were elucidated with spectroscopic and spectrometric methods (1D and 2DNMR, HRESIMS). Compounds 2 and 4 significantly attenuated the growth inhibition induced by lipopolysaccharide (LPS) in normal rat kidney tubule epithelioid (NRK52e) cells (p < 0.05 or p < 0.01). Furthermore, compound 2 significantly reduced the apoptosis (p < 0.05) and the caspase-3/9 expression of NRK52e cells induced by LPS. [GRAPHICS] .
