Targeted drug delivery platforms can increase the concentration of drugs in specific cell populations, reduce adverse effects, and hence improve the therapeutic effect of drugs. Herein, we designed two conjugates by installing the targeting ligand GalNAc (N-acetylgalactosamine) onto atorvastatin (AT). Compared to the parent drug, these two conjugates, termed G2-AT and G2-K-AT, showed increased hepatic cellular uptake. Moreover, both conjugates were able to release atorvastatin, and consequently showed dramatic inhibition of β-hydroxy-β-methylglutaryl-CoA (HMG-CoA) reductase and increased LDL receptors on cell surface.
靶向药物递送平台可以增加特定细胞群体中药物的浓度,减少不良反应,从而提高药物的治疗效果。在此,我们通过将靶向配体半乳糖胺(N-乙酰半乳糖胺)连接到阿托伐他汀(AT)上,设计了两种缀合物。与母体药物相比,这两种缀合物,称为 G2-AT 和 G2-K-AT,显示出增加的肝细胞摄取。此外,两种缀合物都能够释放阿托伐他汀,因此显著抑制β-羟-β-甲基戊二酸单酰辅酶 A(HMG-CoA)还原酶,并增加细胞表面的 LDL 受体。
