Synthesis and antithyroid activity of triazole derivatives

Article abstract of DOI:10.1016/0223-5234(92)90149-U

The synthesis of nitrogen heterocycle derivatives (pyridine, pyrimidine, pyrazine) of 3-mercapto-1,2,4-triazole and 3-mercapto-1-methyl-1,2,4-triazole is described. The antithyroid activity of compounds is evaluated by action on molecular iodine, by action on peroxidase and in vivo on the rat (hormones levels, histology). Pyridyl and pyrimidyl derivatives of mercaptotriazole and mercaptomethyltriazole, as well as (6-methoxy-pyridyl) mercaptomethyltriazole, are the most active. Study over one month does not reveal agranulocytosis.
