Besides, IMD-0354 can inhibit a variety of tumor cells in culture, but its poor water solubility and low utilization have limited its clinical application.Methods: In this study, IMD-0354 was synthesized through esterifying the folate acid (FA) conjugated dextran (Dex) as well as the lauryl alcohol (LA).Results:The particle (IMD/FA-Dex-LA) size was 212.13±10.62nm, the encapsulation efficiency was 89.27±6.51%, and the drug loading was 4.25±0.42%. Cell viability studies indicated that the IMD/FA-Dex-LA effectively inhibited survival of B16F10 cells in culture. Meanwhile, Western Blotting results showed that the nuclear transport of NF-κB was reduced after blocking the IKK pathway, which would thereby suppress melanoma cell division and proliferation. Moreover, subcutaneous tumor implantation experiment revealed that, the drug-loading complex had an obvious effect on suppressing melanoma cells. Findings of this study demonstrated that the IMD-0354 loaded FA-Dex-LA was more effective than IMD-0354 alone.Conclusion: In summary, FA-Dex-LA has been successfully synthesized in this study, which can serve as a carrier for hydrophobic drug. Further, it is believed the FA-Dex-LA can potentially applied in cancer treatment.Keywords: dextran, lauryl alcohol, folate acid, IKK inhibitor, melanoma
