Application of 33282-15-4, 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 Article, and a compound is mentioned, 33282-15-4, 5-(4-Hydroxyphenyl)isoxazole-3-carboxylic acid, introducing its new discovery.
Under physiological conditions healthy bones are maintained by a well tightened balance between osteoclast (OCs) and osteoblast (OBs) activity. Disruption of this balance leads to osteoporosis characterized by decline in bone function and skeletal rigidity. Inhibition of 17beta-hydroxysteroid dehydrogenase type 2 (17beta-HSD2) could help maintaining the appropriate bone mass density by increasing the level of estradiol and testosterone in bone. Herein, we described the synthesis, the physicochemical properties and the biological evaluation of novel N-methylsulfonamide and retro-N-methylsulfonamide derivatives as 17beta-HSD2 inhibitors showing high potency (compound 10f, IC50 = 23 nM), with a good selectivity toward 17beta-HSD1 (the isoenzyme responsible of the reverse reaction), and a likely good in vitro ADME profile. It was also shown that the acidity of the phenolic hydroxy correlates with the inhibitory potency, suggesting pKa as a predictive parameter for the activity of this class of inhibitors.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Application of 33282-15-4. In my other articles, you can also check out more blogs about 33282-15-4
