The present invention is directed compositions for targeted delivery of RNA interference (RNAi) polynucleotides to cell in vivo. The pharmacokinetic modulator improve in vivo targeting compared to the targeting ligand alone. Targeting ligand-pharmacokinetic modulator targeting moiety targeted RNAi polynucleotides can be administered in vivo alone or together with co-targeted delivery polymers.
本发明涉及用于靶向递送RNA干扰(RNAi)多核苷酸至体内细胞的组合物。药代动力学调节剂相较于单独的靶向
配体能够提高体内靶向效果。靶向
配体-药代动力学调节剂靶向基团靶向的RNAi多核苷酸可以单独或与共靶向递送聚合物一起在体内给予。
