Definitions

  • the present invention relates to the use of compounds of the general formula I for increasing insulin sensitivity.
  • the present invention also embraces pharmaceutical compositions comprising these compounds and methods of using the compounds and their pharmaceutical compositions.
  • the present invention relates to use of compounds of the general formula I for reducing blood glucose levels in humans, particularly those afflicted with diabetes.
  • Diabetes mellitus is a systemic disease characterized by disorders in the actions of insulin and other regulatory hormones in the metabolism of carbohydrates, fats and proteins, and in the structure and function of blood vessels.
  • the primary symptom of diabetes is hyperglycemia, often accompanied by glucosuria, the presence in urine of large amounts of glucose, and polyuria, the excretion of large volumes of urine. Additional symptoms arise in chronic or long standing diabetes. These symptoms include degeneration of the walls of blood vessels. Although many different organs are affected by these vascular changes, the nerves, eyes and kidneys appear to be the most susceptible. As such, long-standing diabetes mellitus, even when treated with insulin, is a leading cause of blindness.
  • Type I diabetes is of juvenile onset, ke- tosis-prone, develops early in life with much more severe symptoms and has a near- certain prospect of later vascular involvement. Control of this type of diabetes is difficult and requires exogenous insulin administration.
  • Type II diabetes mellitus is of adult onset, ketosis-resistant, develops later in life, is milder and has a more gradual onset.
  • One of the most significant advancements in the history of medical science came in 1922 when Banting and Best demonstrated the therapeutic effects of insulin in diabetic dogs.
  • Banting and Best demonstrated the therapeutic effects of insulin in diabetic dogs came in 1922 when Banting and Best demonstrated the therapeutic effects of insulin in diabetic dogs.
  • a clear picture of the basic biochemical defects of the disease is not known, and diabetes remains a serious health problem. It is believed that two percent of the United States' population is afflicted with some form of diabetes.
  • the introduction of orally effective hypoglycemic agents was an important development in the treatment of hyperglycemia.
  • Centchroman has also been investigated as an anti-cancer agent for treatment of advanced breast cancer (Misra et al., Int J Cancer 43 (1989), 781 - 783. Recently, centchroman as a race- mate has been found as a potent cholesterol lowering pharmaceutical agent expressed by a significant decrease of the serum concentrations (S.D. Bain et aj., J Min Bon Res 9 (1994), S 394). It is preferred to use the compounds of formula I in the trans configuration. The I enantiomeric forms are preferred over racemic mixtures.
  • the 3,4-diarylchromans are prepared according to known methods, such as those disclosed in U.S. Patent No. 3,340,276 to Carney et aj., U.S. Patent No. 3,822,287 to Bolger, and Ray et al., J Med Chem 19 (1976), 276 - 279, the contents of which are incorporated herein by reference. Conversion of the cis isomer to the trans configuration by means of an organometallic base-catalyzed rearrangement is disclosed in U.S. Patent No. 3,822,287.
  • the optically active d- and l-enantiomers may be prepared as disclosed by Salman et aj. in U.S. Patent No.
  • levormeloxifene the compound of formula II is referred to as levormeloxifene.
  • levormeloxifene is obtained as the free base and the hydrochloride salt.
  • Levormeloxifene, ( - ) - 3R,4R - trans- 7-methoxy-2,2- dimethyl-3-phenyl-4- ⁇ 4-[2-(pyrrolidin-1-yl)ethoxy]phenyl ⁇ chromane is a particular preferred compound.
  • Levormeloxifene may be used in human and veterinary medicine for the regulation of bone metabolism.
  • osteoporosis including post-menopausal osteoporosis and glucocorticoid-related osteoporosis
  • Paget ' s disease hyperparathyroidism
  • hypercalcemia of malignancy other conditions characterized by excessive rates of bone resorption and/or decreased rates of bone formation.
  • insulin sensitizers in particular thiazolidinediones, and there use in treating diabetes mellitus, in particular NIDDM. Insulin sensitizers lowers blood glucose without stimulating insulin secretion, and in some instances even lowers insulin levels in mammals.
  • the 3,4-diphenylchromans of formula I, and in particular levormeloxifene may be administered to mammals, such as humans, to increase insulin sensitivity and/or reduce hyperinsulineamia and/or reduce blood glucose concentrations.
  • 3,4- diphenylchromans can be used for treating hyperinsulineamia, hyperglycemia and for increasing insulin sensitivity in mammals.
  • This invention provides the use of 3,4-diphenylchromans of formula I, and in particular levormeloxifene, or a pharmaceutically acceptable salt thereof, for the manufacture of a pharmaceutical composition for reducing blood glucose concentrations, for treating hyperinsulineamia and/or for treating conditions associated with insulin resistance in mammals, such as humans.
  • the term “treating” or “treatment” is also intended to comprise prophylactic treatment, that is prevention of a disease before its outbreak.
  • the current invention concerns the discovery that the compounds of formula I are useful in mammalian patients with a decreased insulin sensitivity and accompanying hyperinsulineamia in order to revert the metabolic imbalance this condition is associated with.
  • the methods of treatment provided by this invention are practiced by administering to a mammal, eg. a human (male or female), in need of a dose of a 3,4- diphenylchroman of formula I or a pharmaceutically acceptable salt thereof, that is effective to modulate, in particular increase, insulin sensitivity and/or reduce hyperinsulineamia.
  • Preferred 3,4-diphenylchromans of formula I for use in accordance with the present invention comprises centchroman as a racemic mixture, in particular (+/-)-3,4-trans-7- methoxy-2,2-dimethyl-3-phenyl-4- ⁇ 4-[2-(pyrrolidin-1-yl)ethoxy]phenyl ⁇ chromane, and most preferred is levormeloxifene.
  • 3,4-diphenylchromans of formula I may be prepared in the form of pharmaceutically acceptable salts, especially acid-addition salts, including salts of organic acids and mineral acids.
  • salts include salts with non-toxic organic acids such as formic acid, fumaric acid, acetic acid, propionic acid, glycolic acid, lactic acid, pyruvic acid, oxalic acid, succinic acid, gluconic acid, malic acid, maleic acid, tartaric acid, citric acid, ascorbic acid, benzoic acid, salicylic acid, embonic acid, methanesulphonic acid and malonic acid.
  • Suitable inorganic acid-addition salts include salts with non-toxic acids such as hydrochloric, hydro- bromic, sulphuric and phosphoric acids and the like.
  • the acid addition salts may be obtained as the direct products of compound synthesis.
  • the free base may be dissolved in a suitable solvent containing the appropriate acid, and the salt isolated by evaporating the solvent or otherwise separating the salt and solvent.
