6β-Hydroxy prednisolone
Controlled Product6b-Hydroxy prednisolone is a metabolite of prednisolone. The metabolism of prednisolone to 6b-hydroxy prednisolone is catalyzed by the enzyme CYP3A4, which results in the formation of 6β-hydroxyprednisolone and a hydrogen peroxide that reacts with catalase to form water and oxygen. The conversion is dependent on the concentration of galactose, as it provides substrate for CYP3A4. If cyclosporine or other drugs are taken concurrently, they may inhibit the metabolism of 6b-hydroxy prednisolone. The kinetics of 6β-hydroxyprednisolone have been investigated in tissues and plasma samples, and it has been shown that this metabolite has a short half-life in both tissues and plasma samples. This drug can be analysed using chromatography, but endogenous substances such as cortisol can interfere with the process.Formula:C21H28O6Purity:Min. 95%Color and Shape:Light (Or Pale) Yellow SolidMolecular weight:376.44 g/molAcridine orange hydrochloride hydrate

CAS:Fast blue RR salt is a phosphatase inhibitor that belongs to the group of diazonium salts. It is used as an indicator for damaged cells, and it can be used in cell culture. Fast blue RR salt can also be used in biological samples for radiation detection. Fast blue RR salt has been shown to inhibit p-nitrophenyl phosphate (PNPP) phosphatase activity in erythrocytes and lymphocytes from healthy humans. The inhibition is due to the binding of the molecule to the enzyme's active site, which prevents the binding of phosphate ions. This results in a decrease in PNPP hydrolysis, leading to a build-up of PNPP and a decrease in ATP levels. Fast blue RR salt has been shown to have low energy radiation properties, making it more suitable for use with biological samples than other diazonium salts such as Fast red TR salt or Fast green BB salt.Formula:C15H14CIN3O3•(ZnCl2)0Color and Shape:PowderMolecular weight:491.35 g/mol
