Small molecule inhibitors of bacterial motility and a high throughput screening assay for their identification
Certain compounds are provided that can selectively inhibit motile bacteria such as V. cholerae motility. These compounds can indirectly diminish production of cholera toxin and other major virulence required by the cholera bacterium to cause disease.
1. A method for inhibiting motility of a Vibrio cholerae which comprises contacting the Vibrio cholerae with an effective amount of a compound selected from the group consisting of at least one compound selected from the group consisting of at least one compound represented by the following formulae:
and pharmaceutically acceptable salt thereof, solvate thereof, prodrug thereof and mixtures thereof.
2. A method for treating a patient by inhibiting motility of Vibrio cholerae in a patient exposed to the Vibrio cholerae which comprises administering to the patient an effective amount of a compound selected from the group consisting of at least one compound represented by the following formulae:
and pharmaceutically acceptable salt thereof, solvate thereof, prodrug thereof and mixtures thereof.
3. A method for the prophylaxis treatment of a cholera outbreak due to the Vibrio cholerae by administering to a patient in danger of exposure to the Vibrio cholerae at least one compound selected from the group consisting of at least one compound represented by the following formulae:
and pharmaceutically acceptable salt thereof, solvate thereof, prodrug thereof and mixtures thereof.
4. The method according to claim 1 wherein said compound is
5. The method according to claim 2 wherein said compound is
6. The method according to claim 3 wherein said compound is
