subtle structure of the sugar moiety affected the underlying mechanism strongly. In addition, NPCD showed distinct cell-cycle arrest profiles in BxPC3 prostate cells and MCF-7 breast cells, while NPCD glycosides shared similar cell cycle arrest profiles in MCF-7 and BxPC3 cells, which also indicated that not only the indolocarbazole framework as well known before but the sugar moiety can have a profound

抑制剂,可在乳腺肿瘤
细胞系中诱导强烈的G1期阻滞。在这项工作中,介绍了五种N
PCD糖苷的合成及其对八种肿瘤
细胞系的细胞毒活性,以及对它们的细胞周期阻滞特性的研究。结果表明,在N
PCD上引入糖部分并不会影响其大部分细胞毒性活性,而糖部分的微妙结构会强烈影响其潜在机制。此外,N
