Synthetic Route of 52079-23-9, Chemistry is the science of change. But why do chemical reactions take place? Why do chemicals react with each other? The answer is in thermodynamics and kinetics.In a document type is Patent, and a compound is mentioned, 52079-23-9, (S)-(-)-alpha-Hydroxy-gamma-butyrolactone, introducing its new discovery.
1alpha,25-Dihydroxy-24R-fluorocholecalciferol and 1alpha,25-dihydroxy-24S-fluorocholecalciferol, analogs of 1alpha,25-dihydroxy-cholecalciferol which is physiologically the most active metabolite of vitamin D 3, are synthesized in a multistep process from the known substance 1alpha,3beta-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 1alpha,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.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Synthetic Route of 52079-23-9. In my other articles, you can also check out more blogs about 52079-23-9
