5个新的含硫多溴吲哚类化合物:2-甲基亚磺酰基-3-甲硫基-4,5,6-三溴吲哚(1),3-甲基亚磺酰基-2,4,6-三溴吲哚(2),4,6-二溴-2,3-二(methylsulfinyl)indole(3),3,3'-bis(2 '-甲基亚磺酰基-2-甲硫基-4,6,4',6 '-四溴)吲哚(4)和3,3-双(4,6-二溴-2-甲基亚磺酰基)吲哚(5),以及七种已知的含硫多溴吲哚,3-甲硫基-2,4,6-三溴吲哚(6),3-甲硫基-2,1,5,6-四溴吲哚(7),4,6-二溴-2,3-二(甲硫基)吲哚(8)、2,3-二(甲硫基)4,5,6-三溴吲哚(9)、4,6-二溴-2-甲基亚磺酰基-3-(甲硫基)吲哚(10)、4,6-二溴-2-(甲硫基)吲哚(11)和3,3-二(4,6-二溴-2-甲硫基)吲哚(12)已从台湾红棕凹顶藻(Laurencia brongniartii)中分离得到。通过广泛的光谱分析阐明了结构,并在体外测量了它们对选定癌细胞的细胞毒性。
Five new sulfur-containing polybromoindoles, 2-methylsulfinyl-3-methylthio-4,5,6-tribromoindole (1), 3-methylsulfinyl-2,4,6-tribromoindole (2), 4,6-dibromo-2,3-di(methylsulfinyl)indole (3), 3,3'-bis(2'-methylsulfinyl-2-methylthio-4,6,4',6'-tetrabromo)indole (4), and 3,3-bis(4,6-dibromo-2-methylsulfinyl)indole (5), as well as seven known sulfur-containing polybromoindoles, 3-methylthio-2,4,6-tribromoindole (6), 3-methylthio-2,,1,5,6-tetrabromoindole (7), 4,6-dibromo-2,3-di(methylthio)indole (8), 2,3-di(methylthio)4,5,6-tribromoindole (9), 4,6-dibromo-2-methylsulfinyl-3-(methylthio)indole (10), 4,6-dibromo-2-(methylthio)indole (11), and 3,3-bis(4,6-dibromo-2-methylthio)indole (12), have been isolated from the Formosan red alga Laurencia brongniartii. The structures were elucidated by extensive spectral analysis, and their cytotoxicity against selected cancer cells was measured in vitro.
