Adenine-, cytosine-and thymine-containing peptide nucleic acid (PNA) monomers have been synthesized in which either diacetylenic or stearoyl moieties are attached to the N-or C- terminus; the diacetylenic group is embedded within a long hydrocarbon chain. A range of analogous lipophilic functionalized PNA oligomers have been prepared using either solid phase synthesis or a post-synthetic solution phase procedure following cleavage of the ...
