[Antisense DNA]

Abstract

Antisense DNA has been given a big attention as future therapeutic reagents. However, there are several shortcomings including biological instability and low membrane permeability. In order to overcome these shortcomings, the first generation of oligonucleotides has been synthesized. The efficacy of these analogues in vitro or in vivo seems to be promising. In this reviewing article, we mainly describe the intracellular delivery of oligonucleotides from the pharmaceutical point of view.
