Abstract
The antitrypanosomal agent K777•HCl was labeled with carbon-14 to support absorption, distribution, metabolism, and excretion studies of this potential new drug for the treatment of Chagas disease. The radiolabeled compound was prepared in eight steps from [14C(U)]-(l)-phenylalanine with a specific activity of 54.4 mCi/mmol and an overall radiochemical yield of 4.1%.
