ellipticine have been prepared. In addition, a modified synthesis leading to the hitherto unobtainable 8,9-dimethoxy- and 8,9-methylenedioxyellipticines is described. Some of the derivatives described herein exhibit antitumor activity. However, none of the compounds showed activity superior to that of the naturally occurring pyridocarbazoles, ellipticine and 9-methoxyellipticine.
已经制备了玫瑰树碱的几种酰氧基和烷基衍生物。另外,描述了导致迄今无法获得的8,9-二甲氧基-和8,9-亚甲基二氧基玫瑰树碱的修饰的合成。本文所述的一些衍生物表现出抗肿瘤活性。然而,没有一种化合物显示出比天然存在的吡啶并咔唑,玫瑰树碱和9-甲氧基玫瑰树碱更好的活性。
