Definitions
- the present invention relates to methods for treating glaucoma or improving accommodation (i.e. the process by which the eye adjusts for vision at different distances).
- the present invention relates to a method of decreasing the intraocular pressure caused by glaucoma.
- Diabetes is the major determinant to the development of visual disability and blindness in parts of the world unencumbered by causes related to malnutrition or infectious diseases.
- Retinopathy is the leading cause of blindness in diabetics and is a progressive, degenerative disease.
- the level of glucose in the plasma has been widely investigated. It is well accepted that a lower incidence of retinopathy is associated with decreased plasma levels of glucose.
- Ophthalmologic disorders in diabetes include opacification and glaucoma. The occurrence of these indications is correlated with the persistent hyperglycemia of the disease. Although the incidence of glaucoma is significant in diabetic populations, glaucoma affects a substantial portion of the general aging population as well.
- New strategies for pharmaceutical intervention in the treatment of glaucoma based upon new mechanisms of action need to be identified.
- pharmaceutical agents that decrease the intraocular pressure associated with glaucoma are needed.
- the methods of improving accommodation provided by the invention allow one to avoid costly and burdensome optical solutions, such as the use of separate reading glasses or glasses with bifocal lenses.
- the invention relates to a method of treating or ameliorating or preventing glaucoma, decreasing intraocular pressure or improving or ameliorating ocular accommodation in an animal, including a human, comprising administering an intraocular pressure decreasing or ocular accommodation improving amount of a compound of the formula I:
- W and Y are independently N or, respectively, CR W or CR Y .
- Z is O, S or NR Z .
- Q is -CH 2 - or -(CO)-CH 2 -, where the methylene is bonded to a ring nitrogen.
- R w and R ⁇ are independently hydrogen, alkyl, -C ⁇ CR E , -CH 2 -C ⁇ CR P , alkenyl, aryl, arylalkyl, aryloxy, arylthio, amino, alkylamino, arylamino, dialkylamino, diarylamino,
- R E or R p is alkyl, hydrogen, hydroxyalkyl or aryl.
- R is alkyl, -CH 2 -C ⁇ CR P , aryl, arylalkyl, or aroylalkyl.
- R 1 and R 2 are independently hydrogen, alkyl or hydroxymethyl.

- the method provides for administration of classes of inhibitors of advanced glycation.
- the invention further provides for methods to monitor the improvement in the ocular condition during the course of the administration of compound.
- Primary open angle glaucoma is characterized by an increase in intraocular pressure.
- the condition of open angle glaucoma is characterized by an increase in the pressure within a person's eye or eyes, called the intraocular pressure.
- the normal pressure is about 15 mmHg. Elevated pressures of 20-30 mm Hg create a strong risk of damage to the optic nerve and blindness.
- Glucose reacts with proteins by a non-enzymatic, post-translational modification process called non-enzymatic glycosylation.
- the resulting sugar-derived adduct, the advanced glycosylation end product (AGE), matures to a molecular species that is reactive, and can readily bond to amino groups on adjacent proteins, resulting in the formation of AGE cross-links between proteins.

- Compounds of the invention can be used in conjunction with monitoring the improvement (decrease) in the intraocular pressure in a mammal using standard methodology.
- the methods of the inventions can be assessed in animal models for ophthalmologic function.
- improvements in fluid outflow facility can be studied in Rhesus monkeys treated with the compounds and methods of the invention.
- Aged Rhesus monkeys receive a single transcorneal injection of 30 ⁇ L of a test compound (of the invention) at a concentration of about 1 mM in the anterior chamber of one eye, and Barany's solution, as a control, in the adjacent eye. Needle outflow facility is measured under baseline and pilocarpine-stimulated conditions at appropriate time points (for example, 3, 8, 12 and 24 weeks) after the administration of the test compound.
- Increases in outflow facility in the drug treated vs. the control eye under baseline and cholinergic-stimulated e.g.
- pilocarpine conditions at the various time points are compared.
- Various routes of administering the cholinergic agent can be studied to determine their influence on outflow facility measured in the experiments. For instance, an intravenous administration versus a direct administration of pilocarpine can be compared. The above experiment demonstrates one method of measuring the improvement in ophthalmologic function.
- pilocarpine-stimulated accommodation i.e, the process of effecting refractive changes in the shape of the lens
- improvements in pilocarpine-stimulated accommodation can also be assessed in animal studies.
- cholinergic input stimulates the movement of the ciliary muscle to control the shape of the lens, and allows accommodation in conditions of low illumination.
- Accommodation is impaired in a vast majority of individuals and begins to become noticeable to the individual around the age of 40 years.
- changes in accommodative response occur much earlier in life, around 18 years of age, and progress until vision is noticeably impaired.
- Physiological studies on accommodation are conducted following intraocular injection of a test compound and the results are compared relative to the results of control (untreated) animals.
- primates for example, Rhesus monkeys
- PGF 2 ⁇ prostaglandin F 2 ⁇
- both eyes are treated first with 2 ⁇ g of PGF ⁇ -followed 2 hours later with an intraocular injection of 10 ⁇ L of the test compound at a final concentration of 1 mM. No injection is made to the control eye.
- a course of therapy consisting of once a day dosing for a total of 4 days accommodative responses to i.m. pilocarpine administration is performed following phenylephrine refraction.
- test compounds of the invention can be tested to determine corneal penetration to the anterior chamber of the eye following topical administration of eye drops.
- a test compound is assayed in vitro through an intact rabbit cornea for transcorneal penetration in a standard diffusion chamber apparatus. Corneas are mounted in a chamber at 37 °C with the epithelial side exposed to the test compound in Barany's solution. One mL samples are taken from the endothelial side 1 hour after addition of the test compound at a final concentration of 1 mM to the epithelial chamber. The volume of the chamber is replaced with phosphate buffered saline.
- the amount of test compound can be measured using any means that can be used to separate the compound and measure its concentration. For example, an HPLC with an attached UV detector can be used to determine the concentration of the test compound that has penetrated the cornea. Penetration values are also determined at later time points, for example, at 5 hours.
- Assessment of corneal penetration of compounds of the invention can be determined in vivo, for example, in Cynomolgus monkeys. During these studies, the penetration of a test compound into the eye over a period of 5 hours is evaluated using an eye-cup containing a solution of 10 mM of the test compound in Barany's solution. At the end of the experiment the eye cup is removed, the eye is repeatedly flooded with Barany's solution and a sample of intraocular fluid is removed from the anterior chamber with a needle inserted through the cornea. The quantity of the test compound in the intraocular fluid is determined using, for example, HPLC methods.
