Abstract

By using suitably designed chiral, lysine-based PNAs (chPNAs), the stability of complementary chPNAchPNA duplexes can be depressed, maintaining or improving at the same time the stability of the corresponding PNA-DNA duplexes. This approach could be used in order to develop chPNAs able to perform double duplex DNA invasion.
