摘要
Due to the resistance and toxicity of existing anticancer agents, it forces people to continuously develop antitumor drugs that can overcome these side effects. Herein, we designed and synthesized a trifluoromethyl-containing triazole derivative compound TBHPC (tert-butyl (2-(3-(2-hydroxy-4-(trifluoromethyl)phenyl)-1H-1,2,4-triazol-5-yl)phenyl) carbonate). It displays abundant physical properties, such as high thermostability and an obvious pH response. As drug delivery is considered a practical technology, it has been applied for the delivery of the required cargo for tumor therapy. Thus, the nanoporous zeolitic imidazolate framework-8 (ZIF-8), featuring a large specific surface area and porosity, was used to convey TBHPC for a synergistic antitumor effect. Because of the high loading rate of ZIF-8 (10.6 wt %) and the synergistic effect of different components in restrained malignant cells, nearly 60% of H22 cells treated with ZIF-8/TBHPC at a concentration of 5 μg/mL were killed after 24 h of incubation, which exceeded the capacity of pure TBHPC. Moreover, pathological sections showed that ZIF-8/TBHPC showed low biotoxicity to normal tissue in the mice. Furthermore, the intratumoral application of ZIF-8/TBHPC greatly inhibited tumor growth in H22 tumor-bearing mice. Therefore, this ZIF-8/TBHPC system can be regarded as an alternative tactic to fight malignant tumors.
