3-Substitued indoles: One-pot synthesis and evaluation of anticancer and Src kinase inhibitory activities
摘要:
An efficient and economical method was developed for the synthesis of 3-substituted indoles by one-pot three-component coupling reaction of a substituted or unsubstituted benzaldehyde, N-methylaniline, and indole or N-methylindole using Yb(OTf)(3)-SiO2 as a catalyst. All the synthesized compounds were evaluated for inhibition of cell proliferation of human colon carcinoma (HT-29), human ovarian adenocarcinoma (SK-OV-3), and c-Src kinase activity. The 4-methylphenyl (4o and 4p) and 4-methoxyphenyl (4q) indole derivatives inhibited the cell proliferation of SK-OV-3 and HT-29 cells by 70-77% at a concentration of 50 mu M. The unsubstituted phenyl (4d) and 3-nitrophenyl (4l) derivatives showed the inhibition of c-Src kinase with IC50 values of 50.6 and 58.3 mu M, respectively. (C) 2011 Elsevier Ltd.

Graphite oxide (GO) was utilized for the one-pot three-component syntheses of pharmaceutically important 4H-chromenes and 3-amino alkylated indoles in water and solvent-free reaction conditions, respectively. Spectroscopic techniques such as FT-IR, XPS, SEM, TEM, SAED, EDX, PXRD, Raman, and TGA confirmed the formation and thermal stability of GO. These protocols provide green and sustainable reaction
氧化石墨 (GO) 分别用于在水和无溶剂反应条件下一锅三组分合成药学上重要的 4 H-色烯和 3-氨基烷基化吲哚。FT-IR、XPS、SEM、TEM、SAED、EDX、PXRD、拉曼和 TGA 等光谱技术证实了 GO 的形成和热稳定性。这些协议提供了绿色和可持续的反应条件,包括优异的催化活性、良好的产品产率、催化剂的可重复使用性、高官能团耐受性和克级合成。此外,本方法排除了金属毒性、金属废物处理、产品中的金属污染以及挥发性有机溶剂的使用等问题。
