Reactive Oxygen Species (ROS)

Reactive oxygen species (ROS), such as superoxide anion (O2-), hydrogen peroxide (H2O2), and hydroxyl radical (HO•), consist of radical and non-radical oxygen species formed by the partial reduction of oxygen. Cellular ROS are generated endogenously during mitochondrial oxidative metabolism as well as in cellular response to xenobiotics, cytokines, and bacterial invasion.

ROS also activates MAPK pathways by the direct inhibition of MAPK phosphatases. Through PTEN, the PI3K pathway is subject to reversible redox regulation by ROS generated by growth factor stimulation. The activation of autophagy may be a cellular defense mechanism in response to ROS.

Pharmaceutical excipients generally refer to inactive ingredients in pharmaceutical preparations that can improve the stability, solubility and processability of pharmaceutical preparations. Pharmaceutical excipients also affect the absorption, distribution, metabolism and elimination (ADME) process of co-administered drugs. Titanium(IV) oxide can use light energy to generate electron-hole pairs to degrade pollutants. Photons excite electrons in TiO2 to generate active oxygen species (such as ·OH and ·O2-), thereby oxidizing and mineralizing pollutants such as organic compounds and heavy metals. TiO2 can be used in the research of environmental remediation fields such as water treatment, air purification and self-cleaning materials.
