  • br Herein we reported novel NPs


    Herein, we reported novel NPs based on PEO-PBO-loaded LA-SN38 (EBNPs). The EBNPs with small size and narrow distribution, and could effectively control the release rate of SN38. Through in vitro cytotoxi-city and apoptosis assay, we demonstrated EBNPs were more effective in antitumor of human colon cancer cells. Furthermore, cell uptake assay indicated that EBNPs could reduce the Tigecycline of macro-phages and promote the uptake of tumor cells. Pharmacokinetic and biodistribution studies confirmed EBNPs had the advantages of pro-longed blood circulation and enhanced tumor targeting ability. In vivo, EBNPs were more effective in inhibiting the growth of tumor than SNPs and CPT-1, and were well tolerated at the tested dose. In summary, EBNPs are shown as a promising candidate for delivery LA-SN38 for treatment of colorectal cancer. Moreover, EBNPs may be useful as a drug carrier for other drugs in other tumor types.
