title: New thiazane and thiazolidine PNA monomers: synthesis, incorporation into PNAs and hybridization studies.
abstract: New constrained PNA monomers containing a substituted thiazolidine or a thiazane ring were synthesized and incorporated in the center of a 9-mer homothymine PNA. The PNA/DNA hybrids stability was studied by UV-melting experiments which showed that the presence of the modified unit destabilizes the PNA/DNA triplexes.
