title: 4-Guanidino-2-pyrimidinone nucleobases: synthesis and hybridization properties.
abstract: N-Alkylated 4-guanidino-2-pyrimidinone-containing nucleosides, in which the guanidine group mimics the double hydrogen bond donor pattern of protonated cytosine, were introduced in polypyrimidine sequences to explore their triple-helix forming capabilites. UV and CD melting experiments showed that strands containing these base analogues did not form triplex complexes.
