  • Patent number: 5985275
    Abstract: A composition is provided which comprises a protein or peptide containing lysines, wherein at least one of the lysines and/or the N-terminal amino group of the protein or peptide, such as casein, .beta.-lactoglobulin, powdered milk or whey, is modified by contact with an aromatic acid anhydride compound, such as trimellitic anhydride, trimellitic anhydride chloride or 3-hydroxyphthalic anhydride. Additionally a composition is provided wherein a protein or peptide containing arginines is modified by an arginine modifying agent containing at least one carboxyl group, such as p-carboxyphenylglyoxal. The compositions are capable of binding to CD4 cell receptors, such as the HIV-1 or HIV-2 binding site on CD4 cell receptors. The compositions are thus useful for the prevention of HIV-1 or HIV-2 infection, especially by local administration.
