A series of 49 oxygenated tricyclic carbazole derivatives has been tested for inhibition of the growth of Mycobacterium tuberculosis and a mammalian cell line (vero cells). From this series, twelve carbazoles showed a significant anti-TB activity. The four most active compounds were the naturally occurring carbazole alkaloids clauszoline-M (45), murrayaline-C (41), carbalexin-C (27), and the synthetic
已经测试了一系列49个氧化的三环咔唑衍生物对结核分枝杆菌和哺乳动物细胞系(vero细胞)的生长的抑制作用。从该系列中,十二种咔唑显示出显着的抗结核活性。四种活性最高的化合物是天然存在的咔唑生物碱clauszoline-M(45),murrayaline-C(41),carbalexin-C(27)和MIC 90值为1.5至3.7μM的合成咔唑衍生物22。在浓度高达50μM的范围内,活性化合物对哺乳动物细胞系几乎无毒。
