We synthesized five novel uridine-based cationic nucleolipids, introducing basic amino acid residues at the 5′ position of uridine, through 1,3-dipolar cycloaddition, and hydrophobic alkyl moieties at the 2′ and 3′ positions, through carbamate linkages. Their lipoplexes delivered siRNAs efficiently to cells, in vitro, without any severe toxicity.
我们合成了五种新型的尿苷基阳离子核脂质,通过1,3-极性环加成反应在尿苷的5'位点引入了基本氨基酸残基,并通过氨基甲酸酯链接在2'和3'位点引入了疏水的烷基基团。它们的脂质复合物能够有效地将siRNA递送到细胞中,在体外研究中没有表现出严重的毒性。
