The DNA binding characteristics of a series of homologous 2,6-disubstituted anthraquinone threading intercalators bearing one to four ethylene glycol units in their side chains have been studied. Binding constants were measured via surface plasmon resonance (SPR). These compounds bind to an AT-rich hairpin with slightly higher affinity than to a GC-rich hairpin. The binding constants decrease as the

substituted with oligomeric alkoxy functions were synthesized by incorporating the Blaise reaction in the key step. Mono-methylated oligomeric polyethylene glycols were subjected to a three step protocol, namely (i) Michael addition to acrylonitrile, (ii) Blaise reaction with ethyl bromoacetate and (iii) condensation with 4-N,N-diethylamino-2-hydroxybenzaldehyde to give fluorescent water soluble coumarins

A series of oligo(ethyleneoxide) (oligoEO) substituted 2-ureido-pyrimidinones (UPy), differing in the number of ethyleneoxide units and the length of the aliphatic spacer connecting the oligoEO side chain with the UPy group, have been prepared. It was found that variation in these structural parameters strongly influences the dimerization constant (Kdim) of the UPy dimer and the association constant
