Synthesis and in Vitro Evaluation of Novel 5-Nitroindole Derivatives as c-Myc G-Quadruplex Binders with Anticancer Activity

Lead-optimization strategies for compounds targeting c-Myc G-quadruplex (G4) DNA are being pursued to develop anticancer drugs. Here, we investigate the structure-activity- relationship (SAR) of a newly synthesized series of molecules based on the pyrrolidine-substituted 5-nitro indole scaffold to target G4 DNA. Our synthesized series allows modulation of flexible elements with a structurally preserved scaffold. Biological and biophysical analyses illustrate that substituted 5-nitroindole scaffolds bind to the c-Myc promoter G-quadruplex. These compounds downregulate c-Myc expression and induce cell-cycle arrest in the sub-G1/G1 phase in cancer cells. They further increase the concentration of intracellular reactive oxygen species. NMR spectra show that three of the newly synthesized compounds interact with the terminal G-quartets (5′- and 3′-ends) in a 2 : 1 stoichiometry.

Novel methyl indolinone-6-carboxylates containing an indole moiety as angiokinase inhibitors

A novel series of methyl indolinone-6-carboxylates bearing an indole moiety were identified as potent angiokinase inhibitors. The most active compound, A8, potently targeted the kinase activities of vascular endothelial growth factor receptors 2 and 3, and platelet-derived growth factor receptors α and β, with IC50 values in the nanomolar range. In addition, A8 effectively suppressed the proliferation of human umbilical vein endothelial cells, and HT-29 and MCF-7 cancer cells, by inducing apoptosis. Compound A8 is thus a promising candidate for further investigation.
