A small molecule inhibitor targeting EB virus antigen protein, and/or a pharmaceutical composition comprising same, capable of being used for treating diseases caused by EB virus infection, such as, but not limited to, cancer, infectious mononucleosis, chronic fatigue syndrome, multiple sclerosis, systemic lupus erythematosus or rheumatoid arthritis, especially nasopharyngeal carcinoma. The present disclosure further provides a small molecule inhibitor against nasopharyngeal carcinoma, and/or a pharmaceutical composition comprising same, capable of being used for treating nasopharyngeal carcinoma.

Disclosed is an edge-functionalized graphitic material manufactured by using a mechanochemical process. The edge-functionalized graphitic material is manufactured by pulverizing graphite in the presence of a variety of atmospheric agents in the form of gas phase, liquid phase, or solid phase. The edge-functionalized graphitic material, which is a precursor applicable into various fields, is expected to replace the prior art oxidized graphite.
