Abstract: Lactoperoxidase was previously used as a model enzyme to test the inhibitory activity of selenium analogs of anti-thyroid drugs with 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) as a substrate. Peroxidases oxidize ABTS to a metastable radical ABTS.+, which is readily reduced by many antioxidants, including thiol-containing compounds, and it has been used for decades to measure antioxidant activity in biol. samples. We showed that anti-thyroid drugs 6-n-propyl-2-thiouracil, methimazole, and selenium analogs of methimazole also reduced it rapidly. This reaction may explain the anti-thyroid action of many other compounds, particularly natural antioxidants, which may reduce the oxidized form of iodine and/or tyrosyl radicals generated by thyroid peroxidase thus decreasing the production of thyroid hormones. However, influence of selenium analogs of methimazole on the rate of hydrogen peroxide consumption during oxidation of ABTS by lactoperoxidase was moderate. Direct hydrogen peroxide reduction, proposed before as their mechanism of action, cannot therefore account for the observed inhibitory effects. 1-Methylimidazole-2-selone and its diselenide were oxidized by ABTS.+ to relatively stable seleninic acid, which decomposed slowly to selenite and 1-methylimidazole. In contrast, oxidation of 1,3-dimethylimidazole-2-selone gave selenite and 1,3-dimethylimidazolium cation. Accumulation of the corresponding seleninic acid was not observed

YieldReaction ConditionsOperation in experiment
97% With triethylamine; In acetonitrile; at 20℃; Et3N (0.239 mL, 0.98 mmol) was added to a solution of 2-bromo-l-(2,4,6-trimethyl- phenyl)-ethanone (208 mg, 0.86 mmol) and 2-mercapto-l-methylimidazole (98 mg, 0.86 mmol) in CH3CN (8 mL) at room temperature. The reaction was stirred overnight at room temperature then was quenched with of a saturated solution OfNH4Cl. The extraction was conducted with DCM (x2) then the organic phase was washed with brine and dried over MgSO4. The crude residue was the purified by flash chromatography (hexane/EtOAc 0- 40% gradient) to afford the expected compound (229 mg, 97%) as yellow oil.
