Inhibition of vascular endothelial growth factor with a sequence-specific hypoxia response element antagonist [PDF]
, 2004 Vascular endothelial growth factor (VEGF) and its receptors have been implicated as key factors in tumor angiogenesis that are up-regulated by hypoxia. We evaluated the effects of DNA-binding small molecules on hypoxia-inducible transcription of VEGF.

Solution-phase synthesis of pyrrole-imidazole polyamides [PDF]
, 2009 Pyrrole−imidazole polyamides are DNA-binding molecules that are programmable for a large repertoire of DNA sequences. Typical syntheses of this class of heterocyclic oligomers rely on solid-phase methods. Solid-phase methodologies offer rapid assembly on
