Synthesis and Evaluation of the Cytotoxicities of Tetraindoles: Observation that the 5-Hydroxy Tetraindole (SK228) Induces G<sub>2</sub> Arrest and Apoptosis in Human Breast Cancer Cells
Current chemical and biological interest in indole-3-carbinol (I3C) and its metabolites has resulted in the discovery of new biologically active indoles. As part of a program aimed at the development of indole analogues, tetraindoles 1-15 were prepared and their antiproliferative effects on human breast cancer cells were evaluated. The results show that the 5-hydroxy-tetraindole 8 (SK228) has optimum antiproliferative activity against breast adenocarcinoma (MCF 7 and MDA-MB-231) cells and that this activity involves G(2)-phase arrest of the cell cycle with a distinctive increase in the expression of cyclin B1 and phospho-cdc2. Further observations suggest that 5-hydroxy-tetraindole 8 induces apoptosis through externalization of membrane phosphatidylserine, DNA fragmentation, and activation of caspase-3. Given the fact that I3C and its metabolites have been shown to improve therapeutic efficacy and to have a broad range of antitumor activities in human cancer cells, the current findings have important pharmacological relevance as they open a promising route to the development of a potential chemotherapeutic application of tetraindoles as agents for the treatment of breast cancer.

NaY Zeolite Functionalized by Sulfamic Acid/Cu(OAc)<sub>2</sub>as a Novel and Reusable Heterogeneous Hybrid Catalyst in Efficient Synthesis of Bis, Tris, and Tetrakis(indolyl)methanes, 3,4-Dihydropyrimidin-2(1<i>H</i>)-ones, and 2-Aryl-1<i>H</i>-benzothiazoles
An efficient acid‐catalyzed synthesis of some bis, tris, and tetrakis(indolyl)methanes, 3,4‐dihydropyrimidin‐2(1H)‐ones, and 2‐aryl‐1H‐benzothiazoles is reported usingNaYzeolitefunctionalized by sulfamic acid/Cu(OAc)2 (NaYzeolite‐NHSO3H/Cu(OAc)2) in excellent yield. The heterogeneous catalyst has a simple work‐up procedure and could be recycled and reused for six reaction cycles.
据报道,使用通过氨基磺酸官能化的NaY沸石,可以高效地酸催化合成一些双,三和四(吲哚基)甲烷,3,4-二氢嘧啶-2(1 H)-酮和2-芳基-1 H-苯并噻唑。酸/ Cu(OAc)2(NaY沸石-NHSO 3 H / Cu(OAc)2)的产率很高。非均相催化剂的后处理程序很简单,可以循环使用六个反应周期。
