Abstract:
The intraocular use of combinations of lens epithelial cell growth stimulators (e.g., TGF- beta ) and antimetabolites (e.g., mitomycin C) is described. The combination is applied to the capsular bag to prevent or retard the formation of secondary cataracts following cataract surgery. The lens epithelial cell stimulators activate DNA synthesis in dormant lens epithelial cells, and thereby make those cells susceptible to the antimetabolites. This enables the antimetabolites to suppress the proliferation of lens epithelial cells to a much greater extent, relative to the proliferation observed when the metabolites alone are utilized. The increased suppression of the growth of lens epithelial cells results in a significant improvement in the ability to prevent or retard the formation of opacities on the lens capsule (i.e., secondary cataracts).
Abstract:
The use of TGF- beta 3 to reduce the formation of scar tissue as a result of trauma to the cornea of the eye is described. The invention is particularly directed to the use of TGF- beta 3 to reduce the formation of scar tissue in connection with ophthalmic surgical procedures involving the cornea, such as laser irradiation of the cornea. A composition containing TGF- beta 3 is applied to the site of the trauma to alter the production and composition of extracellular matrix synthesized by fibroblasts, and thereby reduce the formation of scar tissue and consequent impairment of vision.
Abstract:
Compounds having anti-inflammatory and anti-oxydant activity are disclosed. The compounds are useful in preventing and treating inflammatory disorders through several mechanisms. Methods of treatment employing these properties of the compounds and corresponding pharmaceutical compositions are disclosed.
Abstract:
The intraocular use of combinations of stromal cell growth stimulators (e.g., TGF- beta ) and antimetabolites (e.g., mitomycin C) in connection with glaucoma filtration surgery is described. The combination is applied to the surgical site to attract, mitogenically activate, and neutralize the potential for extracellular matrix synthesis leading to scar formation by stromal cells. Without such treatment, the formation of scar tissue may lead to impairment of the outflow of aqueous humor at the surgical site, particularly the fistula. The mitogenic activation of the stromal cells makes these cells susceptible to the antimetabolites. This enables the antimetabolites to suppress the proliferation of the fibroblasts and other associated stromal cells to a much greater extent, relative to the proliferation seen when the metabolites alone are utilized. The increased suppression of the proliferation and metabolism of these cells results in a significant improvement in the ability to prevent or retard the formation of scar tissue, and thereby reduces the incidence of fistula closure following glaucoma filtration surgery.

Abstract:
The compounds of the present invention are of the formula (I): A-X-(CH2)n-Y-(CH3)m-Z wherein: A is an non-steroidal anti-inflammatory agent (NSAIA); A-X is an ester or amide linkage derived from the carboxylic acid moiety of the NSAIA, wherein X is O or NR; R is H, C1-C6 alkyl or C3-C6 cycloalkyl; Y, if present, is O, NR, C(R)2, CH(OH) or S(O)n'; n is 2 to 4 and m is 1 to 4 when Y is O, NR, or S(O)n'; n is 0 to 4 and m is 0 to 4 when Y is C(R)2 or is not present; n is 1 to 4 and m is 0 to 4 when Y is CH(OH); n' is 0 to 2; and Z is (a), (b), (c), (d) or (e) wherein: R' and R3 are H, C(O)R, C(O)N(R)¿2, PO3?-, or SO¿3?-; R' is H or C¿1?-C6 alkyl; and R' and R?3¿ together may form a ring having structure: (1) or (2); and provided that when Z is (e), X is not O. The compounds of the present invention also include pharmaceutically acceptable salts of the compounds of formula (I). Methods for treating inflammatory pathologies are disclosed. Particularly, the methods utilize pharmaceutical compositions containing certain compounds having an anti-inflammatory and anti-oxidant moiety covalently linked by an amide or ester bond. The compounds are useful in preventing and treating inflammatory disorders through several mechanisms.
