Abstract

The present invention relates to methods, formulations, and compositions for the treatment of biofilms. In particular, the application discloses isothiocyanate functional surfactants either alone or combination with adjunct agents to treat biofilms. One suitable isothiocyanate functional surfactant is represented by the following chemical structure:

First claim

What is claimed and desired to be secured by Letters Patent of the United States is:

1. A method, comprising the step of administering to a patient having a biofilm a composition comprising an isothiocyanate functional surfactant, wherein the protonated form of the isothiocyanate functional surfactant is represented by the following chemical structure:

2. The method according to claim 1 , wherein the composition comprising the isothiocyanate functional surfactant is administered to the patient at least one of orally, intravenously, intramuscularly, intrathecally, cutaneously, subcutaneously, transdermally, sublingually, buccally, rectally, vaginally, ocularly, otically, and nasally.

3. The method according to claim 1 , wherein the composition comprising the isothiocyanate functional surfactant is topically administered to the patient.

4. The method according to claim 3 , wherein the amount of isothiocyanate functional surfactant in the composition topically administered to the patient ranges from approximately 0.5 nmol/cm2 to approximately 10 μmol/cm2.

5. The method according to claim 4 , wherein the composition comprising the isothiocyanate functional surfactant is a topical preparation selected from the group consisting of ointment, cream, emulsion, lotion and gel.

6. The method according to claim 5 , wherein the composition further comprises one or more pharmaceutical, biological or molecular biological active agents.

7. The method according to claim 6 , wherein the patient is a mammal.

8. The method according to claim 7 , wherein the mammal is a human.
