In order to improve the silencing activity and nuclease resistance of small interfering RNA (siRNA), we designed and synthesized an acyclic thymidine analog containing 4-pentyne-1,2-diol instead of D-ribofuranose. The incorporation of this analog into siRNAs at specific positions in the strands was found to enhance the silencing activity of siRNAs and to increase the resistance of the siRNA to hydrolytic degradation by a 3' exonuclease.
