Abstract:
Nucleic acid aptamers are innovative and promising candidates to block the hallmark event in the prion diseases, that is the conversion of prion protein (PrP) into an abnormal form; however, they need chemical modifications for effective therapeutic activity. This communication reports on the development and biophysical characterization of a small library of chemically modified G-quadruplex-forming aptamers targeting the cellular PrP and the evaluation of their anti-prion activity. The results show the possibility of enhancing anti-prion aptamer properties through straightforward modifications.
