Abstract
The invention relates to an anti-HIV agent comprising as an effective component a plasma protein of which the polarity of the amino group of the amino acid residue constituting the plasma protein is chemically modified into a negative moiety by a carboxylic acid, for example, by maleic anhydride or succinic anhydride. Plasma proteins modified with dicarboxylic anhydride, which are the effective components of the anti-HIV agent of this invention, inhibit the formation of large cells in mixed culturing of HIV infected cells and non-infected cells as well as the direct infection of helper T cells with HIV. They are very safe compounds and are expected to be applicable to the treatment of HIV infected patients
