Summary for Patent: 4,391,824
Title: Ureylenebis (hydroxy naphthalenesulfonic acids)
Abstract:Methods of use and compositions of matter of certain ureides of substituted naphthalenesulfonic acids and salts thereof, useful as inhibitors of connective tissue destruction.
Inventor(s): Siuta; Gerald J. (New City, NY), Bernstein; Seymour (New City, NY)
Assignee: American Cyanamid Company (Stamford, CT)
Application Number:06/286,736
Patent Claims:1. A method of inhibiting connective tissue destruction in a warm-blooded animal suffering from connective tissue destruction disease which comprises administering to said warm-blooded animal an effective connective tissue destruction inhibiting amount of a compound selected from those of the formula: ##STR5## wherein R.sub.1 is selected from the group consisting of hydrogen and --SO.sub.3 A; R.sub.2 is selected from the group consisting of hydrogen, ortho-SO.sub.3 A, ortho-methyl and meta-methyl; and A is selected from the group consisting of hydrogen and a nontoxic pharmaceutically acceptable cation salt.

2. A method of inhibiting the degradation sequelae of collagenase activity in a warm-blooded animal suffering from elevated levels of collagenase which comprises administering to said warm-blooded animals an effective collagenase inhibiting amount of a compound selected from those of the formula: ##STR6## wherein R.sub.1 is selected from the group consisting of hydrogen and --SO.sub.3 A; R.sub.2 is selected from the group consisting of hydrogen, ortho-SO.sub.3 A, ortho-methyl and meta-methyl; and A is selected from the group consisting of hydrogen and a nontoxic pharmaceutically acceptable cation salt.

3. The method according to claim 1 or 2, wherein the compound is 4,4'-[ureylenebis(m-phenylenecarbonylimino)]bis[5-hydroxy-2,7-naphthalened isulfonic acid]tetrasodium salt.

4. The method according to claim 1 or 2, wherein the compound is 3,3'-[ureylenebis(m-phenylenecarbonylimino)]bis[5-hydroxy-2,7-naphthalened isulfonic acid]tetrasodium salt.

5. The method according to claim 1 or 2, wherein the compound is 4,4'-[ureylenebis(3-methyl-p-phenylenecarbonylimino)]bis[5-hydroxy-2,7-nap hthalenedisulfonic acid]tetrasodium salt.

6. The method according to claim 1 or 2, wherein the compound is 4,4'-[ureylenebis(2-methyl-3,1-phenylenecarbonylimino)]bis[5-hydroxy-2,7-n aphthalenedisulfonic acid]tetrasodium salt.

7. The method according to claim 1 or 2, wherein the compound is 4,4'-[ureylenebis(6-methyl-3,1-phenylenecarbonylimino)]bis[5-hydroxy-2,7-n aphthalenedisulfonic acid]tetrasodium salt.

8. The method according to claim 1 or 2, wherein the compound is 5,5.dbd.-[ureylenebis(2-sulfo-4,1-phenylenecarbonylimino)]bis[4-hydroxy-2- naphthalenesulfonic acid]tetrasodium salt.

9. The method according to claim 1 or 2, wherein the compound is administered internally.

10. The method according to claim 1 or 2, wherein the compound is administered topically.

11. The method according to claim 1 or 2, wherein the compound is administered periodontally in the oral cavity.

12. The method according to claim 1 or 2, wherein the compound is administered intra-articularly.

13. The method according to claim 1 or 2, wherein the compound is administered parenterally.

14. The method according to claim 1, wherein said warm-blooded animal is suffering from periodontal disease.

15. The method according to claim 1, wherein said warm-blooded animal is suffering from diseases of the teeth.
