hepatic cytochrome P-450 to an intermediate capable of binding to proteins by a mixed disulfide linkage. The identity of the active metabolite was postulated to be purine-6-sulfenic acid. In the present report, we describe the synthesis of the sulfenic acidderivatives of 6-thiopurine and two structurally similar compounds, 9-methyl-6-thiopurine and 4-mercapto-1H-pyrazolo[3,4-d]-pyrimidine. The unusual
