Definitions

  • Cataracts are an abnormal progressive condition of the lens of the eye, characterized by loss of transparency. A gray- white opacity can be seen within the lens, behind the pupil. Most cataracts are caused by degenerative changes, occurring most often after fifty years of age, however in susceptible patients such as diabetics, cataracts can occur at a much earlier age.
  • cataracts Two types have been described: (1) metabolic or juvenile cataracts, which are observed in children and young adults with uncontrolled diabetes, and (2) senile cataracts which are more common than metabolic cataracts.
  • the cataracts in diabetics are similar to the senile cataracts observed in non-diabetic patients but tend to occur at a younger age (e.g. the aging process is accelerated).
  • cataracts The tendency to develop cataracts is inherited and can be accelerated by diseases such as diabetes. If cataracts are untreated, sight is eventually lost. First, vision is blurred, then bright lights glare diffusely, and finally, distortion and double vision may develop.
  • cataracts have been treated according to the progressive condition of the lens of the eye.
  • senile cataracts are usually treated with excision of the lens and prescription of special contact lenses or glasses.
  • the soft cataracts of children and young adults can either be incised and drained or fragmented by ultrasound, followed by irrigation and aspiration of the fragments through a minute incision.
  • diseases such as diabetes. Diabetes is the leading cause of blindness in adults and accounts for loss of vision in 8% of those who are legally blind in the United States (Klein and Klein, 1995). Sixty-five percent of diabetic patients develop blindness within five years after detection of proliferative retinopathy (Lavine, 1990).
  • tetracycline Using compounds approved for use in humans and available in the oral, injectable and topical routes, such as tetracycline, to treat diseases or conditions such as cataracts has not been suggested.
  • the compound, tetracycline exhibits the following general structure:
  • the numbering system of the ring nucleus is as follows:
  • Tetracycline as well as the 5-OH (Terramycin) and 7-C1 (Aureomycin) derivatives exist in nature, and are well known antibiotics.
  • Natural tetracyclines can be modified without losing their antibiotic properties, although certain elements of the structure must be retained.
  • the modifications that can and cannot be made to the basic tetracycline structure have been reviewed by Mitscher in The Chemistry of Tetracyclines, Chapter 6, Marcel Dekker, Publishers, New York (1978). According to Mitscher, the substituents at positions 5-9 of the tetracycline ring system may be modified without the complete loss of antibiotic properties.
  • CMT chemically modified tetracycline
  • tetracyclines have been described as having a number of other uses.
  • tetracyclines are also known to inhibit the activity of collagen destructive enzymes such as mammalian collagenase, gelatinase, macrophage elastase and bacterial collagenase.
  • tetracyclines have been known to inhibit wasting and protein degradation in mammalian skeletal muscle, U.S. Pat. No. 5,045,538. Furthermore, tetracyclines have been shown to enhance bone protein synthesis in U.S. Pat. No. Re. 34,656 and to reduce bone resorption in organ culture in U.S. Pat. No. 4,704,383.
  • U.S. Pat. No. 5,532,227 to Golub et al. discloses that tetracyclines can ameliorate the excessive glycosylation of proteins.
  • tetracyclines inhibit the excessive collagen cross linking which results from excessive glycosylation of collagen in diabetes.
  • tetracyclines Suppress Metalloproteinase Activity in Adjuvant Arthritis and, in Combination with Flurbiprofen, Ameliorate Bone Damage," Journal of Rheumatology 19:927-938(1992); Greenwald et al., “Treatment of Destructive Arthritic Disorders with MMP Inhibitors: Potential Role of Tetracyclines in, Inhibition of Matrix Metalloproteinases: Therapeutic Potential, "
  • Tetracyclines have also been suggested for use in treating skin diseases.
  • White et al. Lancet, Apr. 29, p. 966 (1989) reports that the tetracycline minocycline is effective in treating dystrophic epidermolysis bullosa, which is a life- threatening skin condition believed to be related to excess collagenase.
  • the effectiveness of tetracycline in skin disorders has also been studied by Elewski et al., Journal of the American Academy of Dermatology 8:807-812 (1983). Elewski et al. disclosed that tetracycline antibiotics may have anti-inflammatory activity in skin diseases.
  • Plewig et al. Journal of Investigative Dermatology 65:532 (1975), disclose experiments designed to test the hypothesis that antimicrobials are effective in treating inflammatory dermatoses.
  • the experiments of Plewig et al. establish that tetracyclines have anti-inflammatory properties in treating pustules induced by potassium iodide patches.
  • tetracyclines in combination with non-steroidal anti-inflammatory agents has been studied in the treatment of inflammatory skin disorders caused by acne vulgaris. Wong et al., Journal of American Academy of Dermatology 1 : 1076- 1081 (1984), studied the combination of tetracycline and ibuprofen and found tetracycline to be an effective agent against acne vulgaris and ibuprofen to be useful in reducing the resulting inflammation by inhibition of cycloxygenase. Funt et al.,
  • doxycycline An antimicrobial tetracycline derivative, doxycycline has been used to inhibit nitrate production.
  • D'Agostino et al., Journal of Infectious Diseases: 177:489-92 (1 98) discloses experiments where doxycycline, administered to mice injected with bacterial lipopolysaccharide (hereinafter LPS), exerted a protective effect by inhibiting nitrate production by an IL-10 independent mechanism.
  • LPS bacterial lipopolysaccharide
  • Experiments carried out in vitro also showed that doxycycline inhibited nitric oxide synthesis by LPS activated macrophages without enhancing endogenous IL-10 release.
  • tetracyclines have been found to be effective in different treatments. However, there has been no suggestion whatsoever that tetracyclines can be used to reduce the risk of cataract development in a mammal. Accordingly, it is one of the purposes of this invention, among others, to provide an economical and relatively uncomplicated method of reducing the risk of cataract development.

Applicants are unaware of any physiological or biochemical basis for expecting that tetracyclines would reduce the risk of cataract formation in a mammal. It is, therefore, surprising that tetracycline derivatives are found to reduce the risk of cataract formation in a mammal.
  • Diabetics develop posterior subcapsular cataracts, characterized by a central opacity in the nucleus and cortex.

  • Figure 1 shows the development of cataracts in untreated Type II ZDF/GMI diabetic rats and Type II ZDF/GMI diabetic rats treated with different tetracycline analogues. Specifically, approximately 60% of untreated Type II ZDF/GMI diabetic rats developed cataracts whereas approximately 42% of Type II ZDF/GMI diabetic rats treated with CMT-8 developed cataracts.
  • Type II ZDF/GMI diabetic rats treated with other tetracycline analogues did not exhibit as low a percentage of cataract development in comparison to Type II ZDF/GMI diabetic rats treated with CMT-8.

Cataracts do not appear to have developed in the CMT-8 treated diabetic rats as they appear very similar to the non-diabetic control rats. Treating diabetic rats with doxycycline to prevent cataract development does not appear to be effective although it is believed that the lack of efficacy was due to the low serum concentration as discussed above.
