Patent number: 6165493Abstract: A method for decreasing the frequency of transmission of human immunodeficiency virus or herpesviruses or for preventing the transmission of or treating a sexually transmitted bacterial infection by administering to a human an anti-human immunodeficiency virus amount or an anti-herpesvirus amount or an anti-bacterial amount of cellulose acetate phthalate (CAP) or hydroxypropyl methylcellulose phthalate (HPMCP), such as in micronized form, or a combination thereof, either alone or in combination with a pharmaceutically acceptable carrier or diluent. The CAP and/or HPMCP may be employed as a suspension of micronized particles and may further contain a water miscible, non-solvent for CAP or HPMCP, such as glycerol.Type: GrantFiled: October 20, 1998Date of Patent: December 26, 2000Assignee: New York Blood Center, Inc.Inventors: Alexander Robert Neurath, Shibo Jiang, Asim Kumar Debnath, Nathan Strick, Gordon Jay Dow

Patent number: 5985275Abstract: 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.Type: GrantFiled: September 29, 1995Date of Patent: November 16, 1999Assignee: New York Blood CenterInventors: Alexander Robert Neurath, Asim Kumar Debnath, Shibo Jiang
