International Classification:

A61K 31/58
A61K 31/70
A01N 43/04
C07J 71/00

US Classification:

514172, 514 27, 540 17

Abstract:

The present invention is based on the discovery that certain chemical compounds isolated from Chinese medicinal herbs are useful as anti-microbial agents, e. g. , anti-bacterial agents, anti-fungal agents, and the like. In particular, the present invention provides compositions useful for treating microbial infections such as, for example, oral microbial infections, including periodontal disease and dental caries.

International Classification:

A61K039/09

US Classification:

424/185100, 424/244100

Abstract:

Dental caries in man may be prevented or treated by oral ingestion of human or humanized murine monoclonal IgG and IgM antibodies that bind to surface antigens of cariogenic organisms, such as . The genetically engineered monoclonal antibodies engage the effector apparatus of the human immune system when they bind to cariogenic organisms, resulting in their destruction. In a preferred embodiment, monoclonal antibodies to cariogenic organisms are produced by edible plants, including fruits and vegetables, transformed by DNA sequences that code on expression for the desired antibodies. The antibodies are applied by eating the plants.

C07K016/46

US Classification:

424/178100, 530/391100

Abstract:

The present invention is based on the discovery of a composition that provides targeted anti-microbial effect. Specifically the composition contains a targeting moiety which recognizes a target microbial organism and an anti-microbial peptide moiety which has anti-microbial activity. In addition, the present invention provides methods of treating a microbial infection, e.g., on mucosal surfaces by using the compositions provided by the present invention.

US Classification:

424/190100, 424/191100, 530/350000

Abstract:

Microbial infection may be treated by administration of a fusion protein comprising one or more recognition sequences and at least one antimicrobial peptide. In preferred embodiments, a linker peptide connects the recognition sequence and one or more antimicrobial peptides. The recognition sequence may be an immunoglobulin molecule, or fragment thereof, that specifically binds to a target antigen present on a pathogen. The recognition sequence may also be a non-immunological polypeptide, providing that the polypeptide binds specifically to a particular ligand. In presently preferred embodiments the recognition sequence is monoclonal antibody that binds specifically to and the antimicrobial peptides are derivatives of histatin.
