Synthesis of DSPE-PEG-Angiopep-2

To synthesize DEPE-PEG-Angiopep-2, 5 mg of DSPE-PEG-Mal was completely dissolved in 10 mL of water. Then, 6 mg of Angiopep-2-cys was added to the solution, and the mixture was stirred at 37°C for 12 hours. The solution was dialyzed (MW3500) to remove excess Angiopep-2-cys. The resulting purified product, DSPE-PEG-Angiopep-2, was then freeze-dried and stored at −20°C for subsequent usage.

DSPE-PEG-Angiopep-2的合成

为了合成DEPE-PEG-Angiopep-2,将5mg DSPE-PEG-Mal完全溶解在10mL水中。然后,向溶液中加入6mg Angiopep-2-cys,并将混合物在37°C下搅拌12小时。将溶液透析(MW3500)以去除多余的Angiopep-2-cys。然后将所得纯化产物DSPE-PEG-Angiopep-2冷冻干燥并储存在-20°C下以备后续使用。

CG/SN-38纳米粒子(NP)的制备与之前报道的相同,但经过了修改。G和1 mg SN-38溶解在20μL DMSO中,然后向溶液中加入1 mL水,然后超声处理5分钟。将制剂用蒸馏水(1L)透析(MW3500)12小时。然后,将NP溶液与一定量的巨噬细胞膜超声2分钟,以获得巨噬细胞膜/IGC/SN-38(M-NP)。此外,通过超声处理(400 W,2 s开/3 s关,2 min)M-NP和预先制备的100μg DSPE-PEG-Angiopep-2,获得1 mL Angiopep-2修饰的M-NP(AM-NP)。
