A simple, rapid, high performance liquid chromatographic (HPLC) method for the analysis of the immunoadjuvant octadecyl tyrosine hydrochloride is described. The HPLC procedure can be applied to the direct determination of amino acid reactants present as contaminants in the adjuvant

Polymorphism is important in the field of solid-state behavior of drug molecules because of the continuous drive for complete control over drug properties. By comparing different structures of a series of L-tyrosine alkyl esters, it became apparent that the ethyl
The fluorescence emission wavelength of alpha-chymotrypsin (CT) correlated with its enantioselectivity (E value) for the resolution of DL-tyrosine ethyl ester. The changes in the E value of the CT due to the changes in the solvent composition were closely related

The inhibition of Helix pomatia arylsulfatase by the synergistic combination of N-acetyl-l-tyrosine ethyl ester and vanadate has been extended to affinity chromatography for purification. In the presence of vanadate, l-tyrosine ethyl ester (TEE), immobilized on CH-Sepharose 4B retained arylsulfatase from
