Antithyroid drug carbimazole and its analogues: synthesis and inhibition of peroxidase-catalyzed iodination of L-tyrosine.


PMID 18954039

Abstract

Synthesis and biological activity of the antithyroid drug carbimazole (CBZ) and its analogues are described. The introduction of an ethoxycarbonyl group in methimazole and its selenium analogue not only prevents the oxidation to the corresponding disulfide and diselenide but also reduces the zwitterionic character. A structure-activity correlation in a series of CBZ analogues suggests that the presence of a methyl substituent in CBZ and related compounds is important for their antithyroid activity.
