A carrier for delivering small interfering RNA (siRNA) into cells includes a cholesterol residue covalently bonded to oligoarginine. Mixing the siRNA with the carrier produces a complex-containing composition. Contacting a cell with the complex-containing composition results in delivery of the siRNA into the cell. Delivery of an siRNA targeted to vascular endothelial growth factor is a treatment for cancer. Methods of making the carrier and complex are also disclosed.
一种用于将小干扰RNA(siRNA)传递到细胞中的载体包括共价键结合到寡精
氨酸的
胆固醇残基。将siRNA与载体混合可产生含有复合物的组合物。将细胞与含有复合物的组合物接触可将siRNA传递到细胞中。将针对血管内皮生长因子的siRNA传递到细胞中是癌症治疗的一种方法。还公开了制备载体和复合物的方法。
