Four new carbazole alkaloids, clausenawallines C-F (1-4), along with 18 known compounds (5-22) were isolated from the roots of Clausena wallichii. Compounds 3, 9, and 22 exhibited significant antibacterial activity against methicillin-resistant Staphylococcus aureus SK1 (MRSA SK1) and Staph. aureus TISTR 1466 with MIC values in the range 4-16 μg/mL, whereas compound 4 showed the highest cytotoxicity against oral cavity cancer (KB) and small-cell lung cancer (NCI-H187) with IC(50) values of 10.2 and 4.5 μM, respectively.
从黄皮 Clausena wallichii 的根部分离得到了四个新的咔唑生物碱,分别为克劳森瓦林 C-F(1-4),以及 18 个已知化合物(5-22)。化合物 3、9 和 22 对耐甲氧西林金黄色葡萄球菌 SK1(MRSA SK1)和金黄色葡萄球菌 TISTR 1466 具有显著的抗菌活性,MIC 值在 4-16μg/mL 范围内,而化合物 4 对口腔癌(KB)和小细胞肺癌(NCI-H187)的细胞毒性最高,IC50 值分别为 10.2 和 4.5μM。
