In the synthesis, for example, an azo coloring matter obtained from an aromatic amine and a phenol derivative is reacted with phosphorus oxychloride in the presence of pyridine and further with water and the prepared phosphoric monoester is dissolved in NaOH, etc., dripped into ethanol under ...
Phosphatases or phosphomonoesterases are the hydrolytic enzymes that cleave the ester bond between the phosphate group and the organic residue of the organic phosphates. Based on the optimum pH for the activity, phosphatases are of two kinds: acid and alkaline. Acid phosphatases show maximum activity...
Oseltamivir is the ethyl ester prodrug of GS-4071, the corresponding acid, which is one of the most potent inhibitors of both influenza A and B virus neuraminidase (sialidase) isoenzymes; these glycoproteins are expressed on the virion surface and are essential for virus replication for both A ...
