Organic Framework

As an emerging kind of crystalline material, the metal-organic framework (MOF) has shown great promise in the biomedical domains such as drug storage and delivery. In this study, a new porous MOF, [[Dy2(H2O)3(SDBA)3](DMA)6] (1, H2SDBA = 4,4′-sulfonyldibenzoic acid, DMA = N,N-dimethylacetamide (C4H9NO)), with uncoordinated O donor sites has been fabricated using a bent polycarboxylic acid organic linker under the solvothermal condition. The structure of the obtained crystalline product has been fully determined by the X-ray single-crystal diffraction, TGA, elemental analysis, XRD, and the gas sorption measurement. Due to the suitable window size and polar atom functionalized 1D channels, the activated 1 (1a) compound was used for the anticancer drug 5-fluorouracil (5-Fu, C4H3FN2O2) loading by a simple impregnation method. A moderate drug loading and pH-dependent drug-release behavior could be observed for 1a. Furthermore, as indicated by the MTT assay, this drug/MOF composite shows low toxicity toward the human normal cells and demonstrates obvious anticancer activity against the human osteosarcoma cell line MG63.

Oridonin (ORI) is a natural active ingredient with strong anticancer activity. But its clinical use is restricted due to its poor water solubility, short half-life, and low bioavailability. The aim of this study is to utilize the metal organic framework material MOF-5 to load ORI in order to improve its release characteristics and bioavailability. Herein, MOF-5 was synthesized by the solvothermal method and direct addition method, and characterized by Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FTIR), Thermogravimetric Analysis (TG), Brunauer–Emmett–Teller (BET), and Dynamic Light Scattering (DLS), respectively. MOF-5 prepared by the optimal synthesis method was selected for drug-loading and in vitro release experiments. HepG2 cells were model cells. MTT assay, 4′,6-diamidino-2-phenylindole (DAPI) staining and Annexin V/PI assay were used to detect the biological safety of blank carriers and the anticancer activity of drug-loaded materials. The results showed that nano-MOF-5 prepared by the direct addition method had complete structure, uniform size and good biocompatibility, and was suitable as an ORI carrier. The drug loading of ORI@MOF-5 was 52.86% ± 0.59%. The sustained release effect was reliable, and the cumulative release rate was about 87% in 60 h. ORI@MOF-5 had significant cytotoxicity (IC50:22.99 μg/mL) and apoptosis effect on HepG2 cells. ORI@MOF-5 is hopeful to become a new anticancer sustained release preparation. MOF-5 has significant potential as a drug carrier material.

A peroxotungstate composite comprising the chromium terephthalate metal–organic framework MIL-101(Cr) and the Venturello peroxotungstate [PO4{WO(O2)2}4]3− (PW4) has been prepared by the impregnation method. The PW4@MIL-101(Cr) composite presents high catalytic efficiency for oxidative desulfurization of a multicomponent model diesel containing the most refractory sulfur compounds present in real fuels (2000 ppm of total S). The catalytic performance of this heterogeneous catalyst is similar to the corresponding homogeneous PW4 active center. Desulfurization efficiency of 99.7% was achieved after only 40 min at 70 °C using H2O2 as an oxidant and an ionic liquid as an extraction solvent ([BMIM]PF6, 2:1 model diesel/[BMIM]PF6). High recycling and reusing capacity was also found for PW4@MIL-101(Cr), maintaining its activity for consecutive oxidative desulfurization cycles. A comparison of the catalytic performance of this peroxotungstate composite with others previously reported tungstate@MIL-101(Cr) catalysts indicates that the presence of active oxygen atoms from the peroxo groups promotes a higher oxidative catalytic efficiency in a shorter reaction time.

Abstract Two-dimensional (2D) nanomaterials generally exhibit enhanced physiochemical and biological functions in biomedical applications due to their high surface-to-volume ratio and surface charge. Conventional cancer chemotherapy based on nanomaterials has been hindered by their low drug loading and poor penetration in tumor tissue. To overcome these difficulties, the novel materials systems are urgently needed. Hereby, the lanthanide-based porphyrin metal organic framework (MOF) nanosheets with promising cancer imaging/chemotherapy capacities are fabricated, which displays superior performance in the drug loading and tumor tissue penetration. The biodegradable PPF-Gd nanosheets deliver an ultrahigh drug loading (>1500%) and demonstrate the stable and highly sensitive stimuli-responsive degradation/release for multimodal tumor imaging and cancer chemotherapy. Meanwhile, PPF-Gd NSs also exhibits excellent fluorescence and magnetic resonance imaging capability in vitro and in vivo. Compared to the traditional DOX chemotherapy, the in vivo results confirm the evident suppression of the tumor growth by the PPF-Gd/DOX drug delivery system with negligible side effects. This work further supports the potential of lanthanide-based MOF nanomaterials as biodegradable systems to promote the cancer theranostics technology development in the future.
