Sericin Protein Particle with Oxidative Stress Property, Method for Preparing the Same and Use Thereof

摘要

The application relates to a sericin protein particle with an oxidative stress property, a method for preparing the same and use thereof. The particle is formed by sericin protein and a tellurium compound. In the method for preparing the sericin protein particle, bis(1-hydroxydodecyl) telluride is first prepared and then mixed with a solution of sericin protein, and a resulting solution is agitated continuously for some time to obtain telluride-modified sericin protein. Then, the solution of the sericin protein is added dropwise into absolute ethanol to obtain a precipitated product. An aqueous solution of the precipitated product and a solution of magnesium ions are mixed and agitated for a certain time to obtain the sericin protein particle with an oxidative stress property. The sericin protein particle disclosed is a hollow particle having a diameter in a range of 600-1250 nm, and is capable of loading biomacromolecule drugs or other components.
