The optimised route to this new class of indolocarbazoles and azaindolocarbazoles involved photocyclisation, with typical yields of 50–60%. These derivatives were screened for anti-cancer activity via topo II inhibition and the NCI-60 cell line assay, with the screening indicating a lack of topo II inhibition, but significant in vitro growth inhibition within this new chemical class, in the low micromolar
通过β-酮酯中间体合成了一系列的5,6-双吲哚和5-吲哚-6-(7-氮杂吲哚)嘧啶酮,并进行了环化条件的筛选。这类新型吲哚并咔唑和氮杂吲哚并咔唑的最优化途径涉及光环化,典型收率为50-60%。通过对topo II抑制和NCI-60细胞系分析筛选了这些衍生物的抗癌活性,筛选结果表明缺乏topo II抑制作用,但是在这种新的化学类别中,在低微摩尔范围内具有显着的体外生长抑制作用。对抗肾癌,黑色素瘤和结肠癌细胞系。
