  2-(Naphthalen-1-ylmethylene)hydrazinecarbothioamide (14, IC50 = 1.1 mu M) was discovered as a highly potent inhibitor of melanogenesis. To define the role of hydrogens (at N1 and N3) and sulfur in 14, a series of analogs 15a-p were synthesized and evaluated for anti-melanogenic activity using melanoma B16 cells under the stimulus of alpha-MSH. It was observed that replacement of either of these hydrogens at N1 or N3 by substituents increases the activity significantly. Conversely, concomitant substitutions decrease the inhibitory potency. In addition, the presence of sulfur in thiosemicarbazone is essential for the activity. (C) 2011 Elsevier Ltd. All rights reserved.
