- 1. Field of the Invention
- The present invention relates to novel disulfide derivatives useful for treating allergic diseases.
- 2. Description of the Related Art
- Antihistamines and mast cell stabilizers are two types of drugs currently used topically to treat allergic diseases. Antihistamine drugs are used to interrupt the allergic effects that histamine causes after it has been released from a mast cell. Many topical antihistamine drugs are marketed. For example, emedastine difumarate and levocabastine hydrochloride are available for ocular allergies (seeOphthalmic Drug Facts 1999, Facts and Comparisons, St. Louis, Mo., pp. 59-80).
- Mast cell stabilizers prevent mast cells from “degranulating” or releasing histamine and other components or “mediators” during an allergic reaction. Examples of ophthalmic drugs marketed as mast cell stabilizers include olopatadine (see U.S. Pat. No. 5,641,805) and cromolyn sodium.
- U.S. Pat. No. 4,705,805 discloses certain disulfide derivatives that are useful as anti-thrombotic agents. The disulfide derivatives suppress blood platelet aggregation. The '705 patent does not disclose the use of disulfide derivatives in the topical treatment of allergic diseases of the eye or nose.
- The present invention provides methods for preventing or treating allergic diseases of the eye, nose, skin, ear, gastrointestinal tract, airways or lung. The methods may also be used to treat manifestations of systemic mastocytosis.

-
- The appropriate isocyanate is added to a stirring solution of the bis amino-disulfide in a solvent such as tetrahydrofuran or methylene chloride at a temperature between −20° C. and 30° C.

The concentration of the compound of formula (I) in the formulations of the present invention will depend on the selected route of administration and dosage form. The concentration of the compound of formula (I) in topically administrable formulations will generally be about 0.00001 to 5 wt. %. For systemically administrable dosage forms, the concentration of the compound of formula (I) will generally range from about 10 mg to 1000 mg.

Conventional excipients include preservatives, buffering agents, chelating agents or stabilizers, viscosity-enhancing agents and others. The chosen ingredients are mixed until homogeneous. After the solution is mixed, pH is adjusted (typically with NaOH or HCl) to be within a range suitable for topical ophthalmic use, preferably within the range of 4.5 to 8.

EXAMPLE 1 Topical Ophthalmic Solution Formulation Ingredient Concentration (wt. %) Compound of formula (I) 0.0001 to 0.2 Dibasic Sodium Phosphate (Anhydrous) 0.5 Sodium Chloride 0.65 Benzalkonium Chloride 0.01 NaOH/HCl q.s. pH 6-8 Purified Water q.s. 100 -
EXAMPLE 2 Topical Ophthalmic Gel Formulation Ingredient Concentration (wt. %) Compound of formula (I) 0.0001 to 0.2 Carbopol 974 P 0.8 Edetate Disodium 0.01 Polysorbate 80 0.05 Benzalkonium Chloride 0.01 NaOH/HCl q.s. pH 6-8 Water for Injection q.s. 100 - To a stirred solution of 2-aminophenyl disulfide (1.5 g, 6 mmol) in 10 ml of THF, was added allyl isocyanate (1.1 ml, 12 mmol). After stirring at room temperature for 5 min, 1 ml of triethylamine was added. The resulting mixture was stirred and refluxed for 18 hr. After cooling, the solvent was evaporated and the solids were filtered off. The filtrate was washed with 5% of HCl, saturated NaHCO3 and saturated NaCl and then dried over MgSO4. Concentration under reduced pressure and chromatography of the residue on silica gel, eluting with 30% of ethyl acetate in hexane to 60% of ethyl acetate in hexane gave 0.31 g of 11 as a white solid.

- Preparation of Cell Suspension
- Methods detailing preparation of monodispersed HCTMC and mediator release studies with these cells have been described (U.S. Pat. No. 5,360,720 and Miller et al, Ocular Immunology and Inflammation, 4(1):39-49 (1996)). Briefly, human conjunctival tissue mast cells were isolated from post-mortem tissue donors obtained within 8 hours of death by various eye banks and transported in Dexsol® corneal preservation medium, or equivalent. Tissues were enzymatically digested by repeated exposure (30 min. at 37° C.) to collagenase and hyaluronidase (2× with 200 U each/gram tissue, then 24× with 2000 U each/gram tissue) in Tyrode's buffer containing 0.1% gelatin. (Tyrode's buffer (in mM): 137 NaCl, 2.7 KCl, 0.35 NaH2PO4, 1.8 CaCl2, 0.98 MgCl2, 11.9 NaHCO3, and 5.5 glucose). Each digestion mixture was filtered over Nitex® cloth (100 μm mesh, Tetko, Briarcliff Manor, N.Y.) and washed with an equal volume of buffer. Filtrates were centrifuged at 825× g (7 min). Pellets were resuspended in buffer then combined for enrichment over a 1.058 g/L Percoll® cushion. The enriched pellet was washed, resuspended in supplemented RPMI 1640 medium and incubated at 37° C. to equilibrate.
- Histamine Release Studies
- Cells were harvested from the culture plate and counted for viability (trypan blue exclusion) and mast cell number (toluidine blue O). Mast cells (5000/tube; 1 mL final volume) were challenged (37° C.) for 15 min with goat-anti-human IgE (10 μg/mL) following treatment (15 minutes; 37° C.) with test drug or Tyrode's buffer. Total and non-specific release controls were exposed to 0.1% Triton X-100 and goat IgG (10 μg/mL), respectively. The reaction was terminated by centrifugation (500× g, 4° C., 10 min). Supernatants were stored at −20° C. until analyzed for histamine content by RIA (Beckman Coulter, Chicago, Ill.).
- Preparation of Test Drug Solutions
- All test drugs were made to solution immediately prior to use. Each was dissolved in DMSO at 10 mM or greater concentration and then diluted in Tyrode's buffer containing 0.1% gelatin over the concentration for evaluation.
- Data Analysis
-
- The data shown in Table 1 indicate that the compounds of formula (I) potently inhibit histamine release from human conjunctival mast cells in an in vitro model of allergic conjunctivitis.

The embodiments described above are therefore considered to be illustrative in all respects and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description.
