Definitions
- the present invention relates to sulfonamides, pharmaceutical compositions containing them and their use as urotensin JJ antagonists
- cardiovascular homeostasis The integrated control of cardiovascular homeostasis is achieved through a combination of both direct neuronal control and systemic neurohormonal activation. Although the resultant release of both contractile and relaxant factors is normally under stringent regulation, an aberration in this status quo can result in cardiohemodynamic dysfunction with pathological consequences.
- the principal mammalian vasoactive factors that comprise this neurohumoral axis namely angiotensin-II, endothelin-1, norepinephrine, all function via an interaction with specific G- protein coupled receptors (GPCR).
- GPCR G- protein coupled receptors
- this peptide has significant hemodynamic and endocrine actions in diverse end-organ systems and tissues:
- osmoregulation effects which include the modulation of transepithelial ion (Na + , CI " ) transport. Although a diuretic effect has been described, such an effect is postulated to be secondary to direct renovascular effects (elevated GFR)
- Urotensin-II receptor Compounds that antagonize the Urotensin-II receptor may be useful in the treatment of congestive heart failure, stroke, ischemic heart disease (angina, myocardial ischemia), cardiac arrhythmia, hypertension (essential and pulmonary), COPD, fibrosis (e.g. pulmonary fibrosis), restenosis, atherosclerosis, dyslipidemia, asthma, (Hay DWP, Luttmann MA, Douglas SA: 2000, Br J Pharmacol: 131; 10-12) neurogenic inflammation and metabolic vasculopathies all of which are characterized by abnormal vasoconstriction and/or myocardial dysfunction.
- Urotensin antagonists may provide end organ protection in hypersensitive cohorts in addition to lowering blood pressure.
- U-II and GPR14 are both expressed within the mammalian CNS (Ames et. al. Nature 1999, 401, 282), they also may be useful in the treatment of addiction, schizophrenia, cognitive disorders/Alzheimers disease, (Gartlon J. Psychopharmacology (Berl) 2001 June; 155(4):426-33), impulsivity, anxiety, stress, depression, pain, migraine, neuromuscular function, parkinsons, movement disorders, sleep-wake cycle, and incentive motivation (Clark et al.Brain Research 923 (2001) 120-127. Functional U-II receptors are expressed in rhabdomyosarcomas cell lines and therefore may have oncological indications.
- Urotensin may also be implicated in various metabolic diseases such as diabetes (Ames et. al. Nature 1999, 401, 282, Nothacker et al., Nature Cell Biology 1: 383-385, 1999) and in various gastrointestinal disorders, bone, cartilage, and joint disorders (e.g. arthritis and osteoporosis); and genito-urinary disorders. Therefore, these compounds may be useful for the prevention (treatment) of gastric reflux, gastric motility and ulcers, arthritis, osteoporosis and urinary incontinence.
- diabetes Ames et. al. Nature 1999, 401, 282, Nothacker et al., Nature Cell Biology 1: 383-385, 1999
