Abstract

A highly stabilizing metal-mediated base pair formed from the canonical nucleobase cytosine (C), the transition metal ion AgI, and the artificial nucleobase 1H-imidazo[4,5-f][1,10]phenanthroline (P) was used in the generation of molecular beacons for the detection of medicinally relevant single nucleotide polymorphisms (SNPs) based on either a C→T or a T→C transition (T: thymine). The beacons exploit the fact that a P–C pair is strongly stabilized in the presence of AgI, whereas a P–T pair is significantly destabilized. A direct correlation of oligonucleotide sequence, duplex stability prior to the addition of AgI, stabilization due to metal-mediated base pair formation, and performance of the molecular beacon was not observed. Nonetheless, the data show for the first time that metal-mediated base pairing can be applied in the detection of medicinally relevant SNPs.
