A mechanistic insight on the biomimetic activity of surface engineered NH2-MIL-125 with α-Asarone for enhanced ROS production in lung cancer cells
Abstract
The α-Asarone-loaded on NH2-MIL-125 (AS@AMIL) was demonstrated to be exceptional potential as a chemo dynamic therapeutic agent (CDT) for lung cancer cells (A549), showing superior efficiency as compared to α-Asarone as well as pristine NH2-MIL-125. The loading of α-Asarone was achieved through cation-π interactions between –NH3+ groups of NH2-MIL-125 and the aromatic ring of α-Asarone. This interaction enriches the framework of AS@AMIL with electrons enhancing the basicity of the framework (O-atoms), which substantially accelerates the decomposition of endogenous H2O2 into reactive oxygen species (ROS) to exhibit enhanced CDT activity. The AS@AMIL exhibited ∼a 1.36-fold increase in ROS production (CDT activity) compared to pristine NH2-MIL-125. The study suggests that the loading of aromatic compounds in amine-functionalized MOFs through cation-π interactions (with –NH3+ groups) can enhance the basicity of MOFs for improved chemodynamic therapeutic activity, and such materials can also be promising as catalysts and CO2 adsorbents.
