TPP-PEG-TK-PLGA

ROS is a by-product of normal aerobic metabolism and plays an important role in cell signal transduction and dynamic balance.The high concentration of ROS in tumor cells is because the stimulation of oncogenes increases the metabolic activity of tumor cells.At the same time,the disorder of mitochondrial function also leads to the increase of ROS concentration in tumor cells.TPP is a white odorless tablet or powder crystal,insoluble in water,soluble in ethanol,easily soluble in organic solvents such as benzene,chloroform,ethylene and acetone, and also soluble in vegetable oil.It has low volatility,transparency,softness, toughness,plasticization,flame retardancy and excellent light stability.
