DNA-selective hybridization and dual strand invasion of short double-stranded DNA using pyren-1-ylcarbonyl-functionalized 4′-C-piperazinomethyl-DNA†
Abstract
Incorporation of a novel pyren-1-ylcarbonyl-functionalized 4′-C-piperazinomethyl-DNA monomer into oligodeoxynucleotides leads to increased thermal stability of duplexes with DNA complements but reduced thermal stability of duplexes with RNA complements. This DNA-selective hybridization is explored for recognition of
