Abstract
The transformation of monotherapy into multimodal combined targeted therapy to fully exploit synergistic efficacy is of increasing interest in tumor treatment. In this work, a novel nanodrug-carrying platform based on iron-based MOFs, which is loaded with doxorubicin hydrochloride (DOX), dihydroartemisinin (DHA), and glucose oxidase (GOx), and concurrently covalently linked to the photosensitizer 5,10,15,20-tetrakis(4-carboxyphenyl)porphyrin (TCPP) in polydopamine (PDA)-encapsulated MIL-101(Fe) (denoted as MIL-101(Fe)-DOX-DHA@TCPP/GOx@PDA, MDDTG@P), is successfully developed. Upon entering the tumor microenvironment, MDDTG@P catalyzes the hydrogen peroxide (H2O2) into hydroxyl radicals (·OH) and depletes glutathione (GSH); thus, exerting the role of chemodynamic therapy (CDT). The reduced Fe2+ can also activate DHA, further expanding CDT and promoting tumor cell apoptosis. The introduced GOx will rapidly consume glucose and oxygen (O2) in the tumor; while, replenishing H2O2 for Fenton reaction, starving the cancer cells; and thus, realizing starvation and chemodynamic therapy. In addition, the covalent linkage of TCPP endows MDDTG@P with good photodynamic therapeutic (PDT) properties. Therefore, this study develops a nanocarrier platform for triple synergistic chemodynamic/photodynamic/starvation therapy, which has promising applications in the efficient treatment of tumors.

Multimodal Imaging-Guided Synergistic Photodynamic Therapy Using Carbonized Zn/Co Metal-Organic Framework Loaded with Cytotoxin Against Liver Cancer. Int J Nanomedicine 2024; 19:4163-4180. [PMID: 38751660 PMCID: PMC11095517 DOI: 10.2147/ijn.s453275] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Accepted: 04/23/2024] [Indexed: 05/18/2024] Open
Abstract
Purpose The study aimed to address the non-specific toxicity of cytotoxins (CTX) in liver cancer treatment and explore their combined application with the photosensitizer Ce6, co-loaded into carbonized Zn/Co bimetallic organic frameworks. The goal was to achieve controlled CTX release and synergistic photodynamic therapy, with a focus on evaluating anti-tumor activity against human liver cancer cell lines (Hep G2). Methods Purified cobra cytotoxin (CTX) and photosensitizer Ce6 were co-loaded into carbonized Zn/Co bimetallic organic frameworks, resulting in RGD-PDA@C-ZIF@(CTX+Ce6). The formulation was designed with surface-functionalization using polydopamine and tumor-penetrating peptide RGD. This approach aimed to facilitate controlled CTX release and enhance the synergistic effect of photodynamic therapy. The accumulation of RGD-PDA@C-ZIF@(CTX+Ce6) at tumor sites was achieved through RGD's active targeting and the enhanced permeability and retention (EPR) effect. In the acidic tumor microenvironment, the porous structure of the metal-organic framework disintegrated, releasing CTX and Ce6 into tumor cells. Results Experiments demonstrated that RGD-PDA@C-ZIF@(CTX+Ce6) nanoparticles, combined with near-infrared laser irradiation, exhibited optimal anti-tumor effects against human liver cancer cells. The formulation showcased heightened anti-tumor activity without discernible systemic toxicity. Conclusion The study underscores the potential of utilizing metal-organic frameworks as an efficient nanoplatform for co-loading cytotoxins and photodynamic therapy in liver cancer treatment. The developed formulation, RGD-PDA@C-ZIF@(CTX+Ce6), offers a promising avenue for advancing the clinical application of cytotoxins in oncology, providing a solid theoretical foundation for future research and development.

[PMID: 38645527 PMCID: PMC11027480 DOI: 10.1039/d4ra00375f] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2024] [Accepted: 03/11/2024] [Indexed: 04/23/2024] Open
Abstract
Despite consecutive efforts devoted to the establishment of innovative therapeutics for cancer control, cancer remains as a primary global public health concern. Achieving controlled release of anti-cancer agents may add great value to the field of oncology that requires the involvement of nanotechnologies. Metal organic frameworks (MOFs) hold great promise in this regard owing to their unique structural properties. MOFs can act as superior candidates for drug delivery given their porous structure and large loading area, and can be prepared into anti-cancer therapeutics by incorporating stimuli-sensitive components into the ligands or nodes of the framework. By combing through chemical and physical features of MOFs favorable for onco-therapeutic applications and current cancer treatment portfolios taking advantages of these characteristics, this review classified MOFs feasible for establishing controlled anti-cancer modalities into 6 categories, outlined the corresponding strategies currently available for each type of MOF, and identified understudied areas and future opportunities towards innovative MOF design for improved or expanded clinical anti-cancer applications.

Int J Biol Macromol 2024; 259:129325. [PMID: 38219935 DOI: 10.1016/j.ijbiomac.2024.129325] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 12/20/2023] [Accepted: 01/06/2024] [Indexed: 01/16/2024]
Abstract
Hepatocellular carcinoma (HPTC) currently ranks as the third leading cause of cancer-related mortality, necessitating an advanced formulation strategy. Recently, lactoferrin (Lf) has been utilized as a specific targeting ligand in HPTC due to its high specificity towards the asialoglycoprotein receptor expressed in cancer cells. Therefore, we present the fabrication of an Lf-decorated carboxymethyl dextran-encased chitosan-coated europium metal-organic framework-based nanobioconjugate (Lf-CMD-CS-CUR@Eu-MOF) for targeted curcumin (CUR) delivery. Briefly, CUR was loaded into Eu-MOF, followed by coating cationic 'CS' on the CUR@Eu-MOF surface. Simultaneously, Lf-decorated CMD was prepared via an esterification reaction. Subsequently, Lf-CMD-CS-CUR@Eu-MOF was synthesized using the Maillard reaction. Various spectral characterizations, drug entrapment, drug content, in vitro drug release, biocompatibility and cell cytotoxicity studies were performed. It exhibited an entrapment efficiency of 88.87 ± 2.1 %, a drug content of 3.45 ± 0.98 %, and a drug loading rate of 34.85 ± 0.6 mg/g. Furthermore, the Lf-CMD-CS-CUR@Eu-MOF exhibits excellent biocompatibility with normal cells. The in vitro dissolution study confirmed a release of 78.12 % of 'CUR' in pH 5.8 phosphate buffer (over 120 h), attributed to the controlled release rate by the 'CS' coating on the surface of CUR@Eu-MOF. The BEL-7402 cell line showed concentration-dependent toxicity of nanobioconjugate to cancerous cells. Therefore, when 'Lf' is surface-decorated onto an appropriate polymeric material, it gains the capability to function as a carrier for transporting 'CUR' to the precise target site within HPTC. In conclusion, Lf-CMD incorporated CS-coated Eu-MOF can provide a promising approach for targeted drug delivery in HPTC management.
