Claims (25)

1. A 13-substituted methacycline compound of the formula:

wherein:

R 4 and R 4′ are each alkyl;

R 5 is hydrogen, hydroxyl, or a prodrug moiety;

R 6 is an alkyl or an aryl group, and pharmaceutically acceptable salts thereof.

2. The 13-substituted methacycline compound of claim 1 , wherein R 5 is hydroxyl.

3. The 13-substituted methacycline compound of claim 1 , wherein R 4 and R 4′ are each methyl.

4. The 13-substituted methacycline compound of claim 1 , wherein R 6 is alkyl.

5. The 13-substituted methacycline compound of claim 1 , wherein R 6 is aryl.

6. A method for treating a tetracycline responsive state in a mammal, comprising administering to said mammal a 13-substituted methacycline compound, such that said tetracycline responsive state is treated, wherein said 13-substituted methacycline compound is of the formula:

wherein:

R 4 and R 4′ are each alkyl;

R 5 is hydrogen, hydroxyl, or a prodrug moiety;

R 6 is an alkyl or an aryl group, and pharmaceutically acceptable salts thereof.

7. The method of claim 6 , wherein said tetracycline responsive state is a bacterial infection.

10. The method of claim 7 , wherein said bacterial infection is associated with E. faecalis.

11. The method of claim 7 , wherein said bacterial infection is resistant to other tetracycline antibiotics.

12. The method of claim 6 , wherein said compound is administered with a pharmaceutically acceptable carrier.

13. A pharmaceutical composition comprising a therapeutically effective amount of a 13-substituted methacycline compound and a pharmaceutically acceptable carrier, wherein said 13-substituted methacycline compound is of the formula:

wherein:

R 4 and R 4′ are each alkyl;

R 5 is hydrogen, hydroxyl, or a prodrug moiety;
