Example 5. In Vitro Buffer Stability

[0227] The in vitro stability effect of certain of the compounds provided herein is assessed in a 10 mM phosphate buffer solution at pH 5 or pH 6 at a targeted concentration of approximately 1 mg/mL.

[0228] Initial preparations of compounds are made in 10 mM Phosphate buffer (pH 6.0). Each compound (1.0-1.5 mg) was weighed in a 4 mL glass vial and 10 mM phosphate buffer pH 6.0 was added targeting API concentration of 0.1% followed by vortex. The typical initial pH was in the range between 4.1 and 4.5, then the pH was adjusted to 6.00?0.10 with 1N NaOH (or 1N HCl if necessary). In order to assess intrinsic solubility of each compound, no solubilizing agents were added. Solubility of the compound is evaluated at this point, including assessment of the purity of the compound at the initial time point using HPLC-MS. Stability is evaluated at day 5 and day 12. Stability evaluation is normalized to the initial purity from day 0. Total concentration is observed over the time period.

[0229] The difference in stability can be seen in FIG. 5. Compounds including a glutarate or carbonate linker were both more stable than a compound including a glutamate linker. Removing an amine from the linker, when comparing glutarate and glutamate linkers, provided a surprisingly more stable compound. A more stable compoundone that paces hydrolysis-permits a likewise pacing of continuity in treatment as compared to a compound that hydrolyses according to a more rapid exponential decayone having a rapid initial hydrolysis followed by a slower tailing hydrolysis. FIG. 6 shows the hydrolysis of the compounds varies in a 10 mM phosphate buffer solution at pH 6 depending on the linker and steroid used. FIG. 7 shows a number of compounds having a glutarate linker that demonstrate a hydrolysis profile within about 10% of one another after 12 days in buffer.

Example 6. In Vitro Pig Liver Esterase (PLE) Stability

[0230] The in vitro enzymatic hydrolysis of compounds was evaluated using pig liver esterase (PLE) enzyme. In a time course study, each compound at 50 UM was incubated with 0.5 U PLE at room temperature in aqueous buffer pH 7 and samples taken at 0, 30, 60, 120, and 240 minutes for subsequent analytical assessment. Sample in the absence of PLE enzyme was run as a control measure of non-enzymatic hydrolysis of the compounds. Samples were analyzed by HPLC-MS for the change in parent compounds well as increase of the predicted metabolites. FIG. 8 shows compounds with a glutarate linker are more susceptible to faster pig liver esterase degradation (cell-free, in vitro enzyme metabolism time course assay) as compared to compounds with a cyclopropyl or succinate linker.

Example 7. Chronic/Severe Allergic Eye Disease (AED) Model

[0231] E5 was formulated in 5% sulfobutylether-?-cyclodextrin (SBE?CD), 10 mM PBS (0.1% NaCl) solution, pH 6 and filtered with a 0.2 ?m PVDF filter. AED was induced in wildtype C57Bl/6 mice. Animals were immunized with one intraperitoneal (i.p) injection of 100 ?g of OVA (InvivoGen) in 300 ng of pertussis toxin (List Biologicals) and 4 mg of aluminum hydroxide (Alum, Thermo Fisher Scientific Pierce) on Day 0. Two weeks later, mice were treated topically QD with 5 ?L OVA (50 ?g/?L) in sterile saline for 5 days. Mice were treated topically BID with 5 uL of vehicle (10% SBE?CD), Lotemax? (Bausch & Lomb; loteprednol etabonate ophthalmic gel 0.5%) or 0.1% E5 in SBE?CD (50:1). The first treatment was administered on Day 14 (2 weeks after initial immunization), 10 minutes prior to OVA instillation followed by a second dose >7 hrs thereafter.

[0232] Assessment was carried out following euthanasia. All four lids were gently inverted under a dissection microscope to expose the posterior lid margin. The number of plugs on the upper and lower eyelids are analyzed and scored for severity as follows: 0 indicates no plug, 1+ indicates appearance of plug. 2+ is assigned to a plug that obstructs the entire MG (Meibomian gland) orifice, 3+ is a plug with a dome that rises above the plane of the eyelid margin, and a 4 is given to a plug that covers a larger surface than the MG orifice (usually with irregular circumference edges).

[0233] Clinical parameters including eyelid edema, chemosis, conjunctival redness, and tearing were each scored on a scale of 0-3+. A score of 0 indicated no evidence of the respective parameter, 1+ is assigned if the response is mild, but distinctly greater than the naive controls; 2+ for a moderate change in the respective parameters that could be noted by slit-lamp microscopy, but not with naked eye; and 3+ if the response is severe enough that could be perceived with naked eye.

[0234] Results are shown in FIG. 9, FIG. 10, and FIG. 11. Clinical scoring shows 0.1% E5 is statistically significantly improved compared to vehicle performed better than loteprednol gel demonstrating statistical significance on day 4 (FIG. 9). 0.1% E5 was effective in lowering both the number and severity of the MG plugs compared to both vehicle and loteprednol (FIG. 10). 0.1% E5 reduced the number of neutrophils in the Meibomian gland and conjunctiva (FIG. 11).

Example 8. In Vivo PK/PD Ocular Surface Corneal Wound Healing Model

[0235] E5 was formulated in 3.5% sulfobutylether-?-cyclodextrin (SBE?CD), 10 mM PBS, pH 6 and filtered with a 0.2 ?m PVDF filter.

[0236] Anesthetized animals (8-10 weeks old male C57/B1/6 mice) were placed under a dissecting microscope and eyes proposed. Corneas of OD eyes were demarcated by centrally, and softly, marking the perimeters of the debridement area with a 2 mm trephine. A 10 ?L drop of PBS was placed on the eye and an Algerbrush with a 0.5 mm burr attachment was utilized to carefully remove the epithelium within the demarcated area of the cornea. Topical fluorescein (Sigma) was applied, and excess fluorescein flushed prior to capture of a baseline image of the wound (time=0). Topical treatments were administered at t=0 and t=6 hours post-injury by applying 5 UL to the surface of the debrided eye. Fluorescein-stained corneas were imaged again 24 h after injury. Percent re-epithelialization was assessed by analysis of imaged corneas with Image J (NIH, Bethesda, MD).

[0237] Results are shown in FIG. 12 and FIG. 13. The corneal wound healing model shows the ability of 0.1% E5 to reduce eye surface inflammation (MPO; myeloperoxidase) without having the negative effect on epithelium regrowth/healing 24 hrs after epithelium debridement. 0.1% dexamethasone and 0.5% loteprednol were used as positive clinically relevant controls. 0.1% E5 did not affect the recovery of epithelium in this model (FIG. 12). 0.1% E5 significantly reduced the cornea inflammation in comparison to PBS (phosphate-buffered saline) vehicle and loteprednol groups (FIG. 13).

Example 9. Intraocular Pressure Study in Normotensive Dutch Belted Rabbits

[0238] E5 was formulated in 3.5% or 6.5% sulfobutylether-?-cyclodextrin (SBE?CD), 10 mM PBS, pH 6 and filtered with a 0.2 ?m PVDF filter. A single dose was administered and the intraocular pressure was measured, e.g., with a pneumatonometer, for 32 hours post-dose. Results are shown in FIG. 14 and FIG. 15. A single dose of E5 lowered IOP in a dose-dependent manner with no hyperemia observed (FIG. 14 and FIG. 15).

Example 10. In Vitro Steroid and ROCKi Activity

[0239] Activities of certain compounds and components of compounds described herein were assayed. Results are shown in Table 7. It was observed that E5 and E15 possess both ROCKi and steroid potency and activity. Rho-associated protein kinase 2=ROCK2; Rho-associated protein kinase 1=ROCK1; Porcine Trabecular Meshwork cells=PTM; Human Trabecular Meshwork cells=HTM; Splenic Interleukin-23=SPNL IL23; and Tumor Necrosis Factor ?=TNF?.
