| Popis: | Ovarian cancer remains one of serious hazards to human health due to many drawbacks of existing available treatment options. In this study, a multifunctional chemo-thermo combined therapy nanoplatform (OMCNPID) was successfully prepared, which is composed of I6P8 peptide as a targeting moiety to interleukin-6 receptors (IL-6Rs), oxidized mesoporous carbon nanospheres (OMCN) as a near infrared (NIR)-triggered drug carrier and doxorubicin (DOX) as a chemotherapeutic drug and fluorescent agent. The synthesized multifunctional nanoplatform displayed high storage capacity for drugs and excellent photothermal properties. Besides, DOX was rapidly released from OMCNPID at the condition of low pH and NIR laser irradiation due to the dissociation of DOX from graphitic cores of OMCN. In vitro experimental results verified that OMCNPID could be markedly taken up by SKOV-3 monolayer cells and tumor spheroids, and revealed a remarkable synergistic chemo-photothermal effect against ovarian cancer. All the results demonstrated that OMCNPID is a pH/NIR dual-stimulus responsive nanoplatform and can achieve efficient chemo-thermo combined therapy. |
