A series of 2(3H)-thiazole thiones 3-5 was synthesized and evaluated for tyrosinase inhibition and DPPH radical scavenging activities. Among them, 3-methyl-4-phenyl-2(3H)-thiazole thione (4a) showed good tyrosinase inhibitory activity, even better than that of the well-known tyrosinase inhibitor, namely, kojic acid. From the structure-activity point of view, although it was found ...
