  • Publication number: 20240390513
    Abstract: A composition is useful for treating inflammatory diseases, in which hydrophobic manganese oxide is loaded on micelles so as to be stably protected in vivo thereby easily being delivered to a target site. In addition, the hydrophilic and hydrophobic regions of micelles are bonded with a reactive oxygen species (ROS) cleavable linker and decomposed in response to active oxygen species at an inflammatory site, thereby efficiently releasing hydrophobic manganese oxide particles, and released hydrophobic manganese oxide can generate oxygen to change the microenvironment of the target site, thereby improving the effects of physiologically active substances loaded on the micelles.
