What is 2-Amino-2-phenylacetic acid?
Description
2-Amino-2-phenylacetic acid is a natural compound that has been identified as a selective inhibitor of cyclooxygenase 2 (COX-2), and it exhibits antiinflammatory activity. It has been shown to inhibit COX-2 at low concentrations and to be less potent than aspirin in inhibiting COX-1. It is also an amide, with a molecular weight of 296. In order to determine the structure of it, XRD data was collected from the monosodium salt form of the compound. The ester hydrochloride form was used for enzyme activity assays because it is more soluble in water than the free base form. The synthesis of 2-Amino-2-phenylacetic acid was achieved through a two step process involving amide formation and hydrolysis.
