The Donor Activity for Peroxidase and the Effect on the Thyroid Gland of Certain Tyrosine Derivatives.

Abstract
Tyrosine and some tyrosine derivatives were tested as donors for my eloper oxidase by an ampero-metric technique. Some of the more active compounds (tyrosine ethylester, tyrosine-pentylester and dimethyltyramine) were also tested for thyrostatic action in rats, but were found to be inactive in this respect.
