Abstract | AIM: MATERIALS & METHODS:
Octreotide acts as a modified ligand for receptor-mediated targeting and the coated Fe3O4 nanoparticles offer the magnetic targeting property. SSTR2 overexpressed A549 cells and S180 cells were chosen to explore the targeting ability and antitumor effect of the oleanolic acid (OA)-loaded OMlips in vitro and in vivo. RESULTS: The OMlips platform significantly improves the targeting, penetrating and accumulation of OA at the SSTR2 overexpressed cells and SSTR2-positive tumor-bearing mice. CONCLUSION: The OA-loaded OMlips have better antitumor effect and lower systemic toxicity. Such a receptor-mediated and magnetically-orienting dual-targeting drug nanocarriers may have great potentials in clinical practice.
