high selectivities against a wide range (>50) of other CNS relevant receptors. First, structure-affinity relationships of these ligands are discussed. In terms of functionality, high-affinity antagonists, as well as agonists and even partial agonists, were prepared. Compounds 19c and 19g represent the highest-affinity 5-HT(6) agonists ever reported in the literature. These valuable tool compounds should

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
bearing an indole moiety were identified as potent angiokinase inhibitors. The most active compound, A8, potently targeted the kinase activities of vascular endothelial growthfactorreceptors 2 and 3, and platelet-derivedgrowthfactorreceptors 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
