Eighteen new β‐carboline‐based indole‐4,7‐quinone derivatives (12a–i and 13a–i ) were designed and synthesized, and their in vitro and in vivo antiproliferative activities were studied. Most of target compounds showed strong inhibition on three human tumor cells' proliferation. In particular, the most active compound 13g not only displayed more prominent antiproliferative activities than β‐lapachone, a clinical antitumor candidate, but also exerted significant NAD(P)H: quinone‐oxidoreductase‐1 (NQO1) inhibitory activity and NQO1‐dependent cytotoxicity in HT29 cells. Furthermore, 13g dose‐dependently induced high ROS levels in HT29 cells, and selectively inhibited cancer cell but not non‐tumor colon cell proliferation in vitro. Importantly, 13g promoted HT29 cell apoptosis and DNA damage by regulating relative apoptotic proteins and H2AX expression. Finally, 13g displayed significant growth inhibition of HT29 human colorectal adenocarcinoma xenograft in mice without overt toxicity.

作为 NAD(P)H 的新型 β-咔啉基吲哚-4,7-醌衍生物：醌氧化还原酶-1 抑制剂，通过诱导活性氧、细胞凋亡和 DNA 损伤具有有效的抗肿瘤活性。

设计并合成了18 种新的基于 β-咔啉的吲哚-4,7-醌衍生物（12a-i和13a-i），并研究了它们的体外和体内抗增殖活性。大多数目标化合物对三种人类肿瘤细胞的增殖表现出强烈的抑制作用。特别是，活性最强的化合物13g不仅显示出比临床抗肿瘤候选药物 β-拉帕酮更显着的抗增殖活性，而且还发挥了显着的 NAD(P)H：醌-氧化还原酶-1 (NQO1) 抑制活性和 NQO1 依赖性细胞毒性在 HT29 细胞中。此外，13g剂量依赖性地诱导 HT29 细胞中的高 ROS 水平，并在体外选择性抑制癌细胞但不抑制非肿瘤结肠细胞增殖。重要的是，13g通过调节相对凋亡蛋白和 H2AX 表达促进 HT29 细胞凋亡和 DNA 损伤。最后，13g在小鼠中显示出对 HT29 人结肠直肠腺癌异种移植物的显着生长抑制，而没有明显的毒性。
