Biomaterials 2022; 287:121681.

Abstract
Stimulus-responsive self-assembling prodrug-based nanomedicine has emerged as a novel paradigm in controlled drug delivery. All-trans retinoic acid (RA), one of vitamin A metabolites, induces apoptotic cancer cell death, but its clinical applications are limited by weak anticancer efficacy. To fully maximize the therapeutic potential of RA, we exploited the unique chemistry of arylboronic acid which undergoes hydrogen peroxide (H2O2)-triggered degradation to release quinone methide (QM) that alkylates glutathione (GSH) to disrupt redox homeostasis and is also converted into hydroxybenzyl alcohol (HBA) to suppress the expression of vascular endothelial growth factor (VEGF). Here, we report that boronated retinoic acid prodrug (RABA) can be formulated into self-deliverable nanoassemblies which release both RA and QM in a H2O2-triggered self-immolative manner to exert cooperative anticancer activities. RABA nanoassemblies exert anticancer effects by inducing reactive oxygen species (ROS)-mediated apoptosis, eliciting immunogenic cell death (ICD) and suppressing angiogenic VEGF expression. The excellent anticancer efficacy of RABA nanoassemblies can be explained by benefits of self-assembling prodrug-based drug self-delivery and cooperative anticancer actions. The design strategy of RABA would provide a new insight into the rational design of self-deliverable and self-immolative boronated prodrug nanoassemblies for targeted cancer therapy.

[PMID: 35519742 PMCID: PMC9055350 DOI: 10.1039/d0ra03069d] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2020] [Accepted: 05/08/2020] [Indexed: 12/19/2022] Open
Abstract
In clinical tumor therapy, traditional treatments such as surgery, radiotherapy and chemotherapy all have their own limitations. With the development of nanotechnology, new therapeutic methods based on nanomaterials such as photothermal therapy (PTT) have also emerged. PTT takes advantage of the poor thermal tolerance of tumor cells and uses the heat generated by photothermal reagents to kill tumor cells. A transition metal sulfide represented as Cu2S is an ideal photothermal reagent because of its easy preparation, high extinction coefficient and photothermal conversion efficiency. Surface modification of nanoparticles (NPs) is also necessary, which not only can reduce toxicity and improve colloidal stability, but also can provide the possibility of further chemotherapeutic drug loading. In this work, we report the fabrication of Tween-20 (Tw20)-modified and doxorubicin (Dox)-loaded Cu2S NPs (Cu2S/Dox@Tw20 NPs), which significantly improves the performance in tumor therapy. Apart from the enhancement of colloidal stability and biocompatibility, the drug loading rate of Dox in Tw20 reaches 11.3%. Because of the loading of Dox, Cu2S/Dox@Tw20 NPs exhibit chemotherapeutic behaviors and the tumor inhibition rate is 76.2%. Further combined with a near-infrared laser, the high temperature directly leads to the apoptosis of a large number of tumor cells, while the release of chemotherapeutic drugs under heat can not only continue to kill residual tumor cells, but also inhibit tumor recurrence. Therefore, with the combination of PTT and chemotherapy, the tumor was completely eliminated. Both hematological analysis and histopathological analysis proved that our experiments are safe. In clinical tumor therapy, traditional treatments such as surgery, radiotherapy and chemotherapy all have their own limitations.![]()
