Due to their great instability, phosphodiester antisense oligonucleotides (PO-ODNs) are rapidly degraded in the intracellular environment, which limits their biological activity. The release of PO-ODNs during a prolonged period of time could however greatly enhance their antisense effect by creating a pool of intact PO-ODNs at any time point. Poly-beta-aminoesters are biodegradable cationic polymers which show potential for the controlled release of short DNA fragments like ODNs and small… CONTINUE READING
