Summary for Patent: 6,660,762

Title:	Methods and compositions to treat lung diseases
Abstract:	Methods, compositions, pharmaceutical compositions and packaged pharmaceuticals that include porphyrin analogues are described. The porphyrin analogues identified in the present application can be used to treat various pneumoconiosic diseases, including berylliosis. Effective treatment by the porphyrin analogues is best accomplished via an aerosol.

Application Number:	10/146,607
Patent Claims:	1. A method to treat a subject having berylliosis comprising the step of administering to the subject a therapeutically effective amount of a porphyrin analogue or a pharmaceutically acceptable salt, ester, amide, or prodrug thereof. 2. The method of claim 1, wherein the porphyrin analogue or pharmaceutically acceptable salt, ester, amide, or prodrug thereof is administered as an aerosol. 3. The method of claim 2, wherein the aerosol is administered in conjunction with an inhaler. 4. The method of claim 1, wherein the porphyrin analogue is hemin, meso-tetra (4-carboxyphenyl) porphyrin, phthalocyanine tetrasulfonate, meso-tetra (4-sulfonatophenyl) porphyrin, or magnesium phthalocyanine tetrasulfonate tetra sodium salt porphyrin. 5. The method of claim 1, wherein the porphyrin analogue comprises at least 4 interconnected heteroatoms in an organic structure that provides a binding site for a metal ion associated with pneumoconiosis. 6. The method of claim 5, wherein the heteroatoms are each independently nitrogen, oxygen, sulfur, or selenium and combinations thereof. 7. The method of claim 6, wherein each of the four heteroatoms are nitrogen atoms. 8. The method of claim 6, wherein at least two of the four heteroatoms are nitrogen atoms. 9. The method of claim 6, wherein the porphyrin analogue has at least one functional group appended thereto. 10. The method of claim 9, wherein the functional group comprises a sulfur moiety. 11. The method of claim 10, wherein the sulfur moiety is a sulfonate. 12. The method of claim 9, wherein the functional group comprises a carboxylate. 13. The method of claim 12, wherein the porphyrin analogue chelates the metal ion associated with pneumoconiosis. 14. The method of claim 13, wherein the metal ion is an element, a metal oxide, a mineral or a metal salt. 15. The method of claim 5, wherein the porphyrin analogue has the following formula (Formula I): ##STR2## wherein each A, independently, is a heteroatom; each Z, independently, is a carbon atom or a heteroatom; each Y, independently, is a hydrogen atom, a functional group or when Z is a heteroatom, forms part of a double bond; S and T are each, independently, a functional group or together form a ring; and each n is an integer of 1 or 2 to complete the carbon chain. 16. The method of claim 15, wherein each A is a nitrogen atom, each Z is a nitrogen atom or a carbon atom, S and T together form a pyrrole or a phenyl group, and n=1, wherein the pyrrole or phenyl group is substituted with at least one sulfur containing moiety. 17. The method of claim 16, wherein the sulfur containing moiety is a sulfonate. 18. The method of claim 5, wherein the porphyrin analogue has the following formula (Formula II): ##STR3## wherein each A, independently, is a heteroatom; each Z, independently, is a carbon atom or a heteroatom; each Y, independently, is a hydrogen atom, a functional group or when Z is a heteroatom, forms part of a double bond; and S and T are each, independently, a functional group or together form a ring. 19. The method of claim 18, wherein each A is a nitrogen atom, each Z is a nitrogen atom or a carbon atom, S and T together form a pyrrole or a phenyl group, and wherein the pyrrole or phenyl group is substituted with at least one sulfur containing moiety. 20. The method of claim 19, wherein the sulfur containing moiety is a sulfonate.
