A conjugate of the ligand of FS2 venom dihydropyridine receptors with a cationic arginine-containing oligopeptide was synthesized. It was found that the conjugate provides siRNA delivery to murine myotubes differentiated in vitro. The effect of RNA interference with the use of siRNA complexes with the conjugate was observed when siRNA concentrations were an order of magnitude lower than those used in the case of siRNA complexes with a non-conjugated oligopeptide.
