    摘要: The present invention provides novel adenosine receptor antagonists, more particularly, A1 adenosine receptor antagonists of formula (I). Pharmaceutical compositions comprising an A1 adenosine receptor antagonist of formula (I) and a pharmaceutically acceptable carrier are further provided. Compositions also include diagnostic assay-type probes comprising a novel A1 adenosine receptor antagonist of formula (I) that is labeled or conjugated with radioactive or non-radioactive material. Methods for treating A1 adenosine receptor related disorders comprising administering an A1 adenosine receptor antagonist of formula (I) are also disclosed. The novel A1 adenosine receptor antagonist compositions of formula (I) find further use in diagnostic and imaging methods. wherein R3 is Alk14ArR16, and wherein Alk14 is C1-8 straight or branched alkylene or alkenylene.

    摘要: 1.alpha.,25-Dihydroxy-24R-fluorocholecalciferol and 1.alpha.,25-dihydroxy-24S-fluorocholecalciferol, analogs of 1.alpha.,25-dihydroxy-cholecalciferol which is physiologically the most active metabolite of vitamin D.sub.3, are synthesized in a multistep process from the known substance 1.alpha.,3.beta.-dihydroxyandrost-5-en-17-one. The new analogs are characterized by the ability to increase intestinal calcium transport, increase serum calcium and phosphate concentrations and to increase the deposition of these minerals in bones. These compounds will find a ready application as substitutes for natural 1.alpha.,25-dihydroxycholecalciferol in the treatment of disease states characterized by metabolic calcium and phosphate deficiencies. Exemplary of such disease states are the following: osteomalacia, osteoporosis, rickets, osteitis fibrosa cystica, renal osteodystrophy, osteosclerosis, anti-convulsant treatment, osteopenia, fibrogenesis-imperfecta ossium, secondary hyperparathyrodism, hypoparathyroidism, hyperparathyroidism, cirrhosis, obstructive jaundice, drug induced metabolism, medullary carcinoma, chronic renal disease, hypophosphatemic VDRR, vitamin D-dependent rickets, sarcoidosis, glucocorticoid antagonism, malabsorption syndrome, steatorrhea, tropical sprue, idiopathic hypercalcemia and milk fever.
