The review describes key aspects of the synthesis and biological activities of conjugates of oligonucleotides and their analogues with synthetic peptides, in particular aimed towards gene silencing applications. The common methods of synthesis of oligonucleotide-peptide conjugates (OPCs) and PNA-peptide conjugates (PPCs) are described, which include both total solid-phase and fragment coupling approaches. In addition, various applications of conjugates as gene silencing agents are outlined. These include antisense and steric block applications in mammalian cells of OPCs, PPCs and phosphorodiamidate morpholinooligonucleotide (PMO)-peptide conjugates, gene silencing in bacteria, various DNA targeting applications, and recent reports of gene silencing activities of siRNA-peptide conjugates. A table listing all peptides used as oligonucleotide conjugates for gene silencing applications is also included.
