    • Chemical Class:

      A member of the class of 1,3-dihydroimidazole-2-thiones that is 1,3-dihydro-2<element>H</element>-imidazole-2-thione in which one of the nitrogens is substituted by a 5,7-difluoro-1,2,3,4-tetrahydrona phthalen-2-yl group while the carbon adjacent to it is substituted by an aminomethyl group (the <stereo>S</stereo> enantiomer). It is a potent and selective inhibitor of both bovine and human dopamine <locant>beta</locant>-hydroxylase, an enzyme that catalyzes the conversion of dopamine to norepinephrine. ChEBI CHEBI:139334
