Unique Gene‐Silencing and Structural Properties of 2′‐Fluoro‐Modified siRNAs

Abstract

With little or no negative impact on the activity of small interfering RNAs (siRNAs), regardless of the number of modifications or the positions within the strand, the 2′-deoxy-2′-fluoro (2′-F) modification is unique. Furthermore, the 2′-F-modified siRNA (see crystal structure) was thermodynamically more stable and more nuclease-resistant than the parent siRNA, and produced no immunostimulatory response.
