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.

Claims (11)

1. A method of inhibiting the activity of a yeast or fungal microorganism, said method comprising contacting the yeast or fungal microorganism with a composition comprising polyphyllin D as an active ingredient, in an amount sufficient to inhibit the activity of said yeast, or fungal microorganism.

2. The method of claim 1 , wherein the microorganism is an oral pathogenic microorganism.

3. The method of claim 1 , wherein the microorganism causes dental caries or periodontal disease.

4. The method of claim 1 , wherein the microorganism is on a mucosal surface.

5. The method of claim 1 , wherein the microorganism is associated with a tooth structure.

6. The method of claim 1 , wherein the microorganism is associated with an infection in an epithelial tissue.

7. The method of claim 1 , wherein the microorganism is a drug resistant microorganism.

8. The method of claim 1 , wherein the microorganism is a fungal microorganism.

9. The method claim of 1 , wherein the microorganism is a drug resistant Candida.

10. The method of claim 1 , wherein the polyphyllin D is naturally occurring.

11. The method of claim 1 , wherein the polyphyllin D is chemically synthesized.
