and 1,3-disubstituted thioureas 2a–k were evaluated against melanin formation in melanoma B16 cell line and mushroom tyrosinase. Inhibitory activity of tyrosinase of 1-phenylthioureas 1a–k is parallel to their melanogenic inhibition. Thus, the melanogenic inhibition in melanoma B16 cells of 1-phenylthioureas could be the result of inhibition of tyrosinase. However, 1,3-diaryl or 1-phenyl-3-alkylthioureas
评估了一系列1-苯基硫脲1a - k和1,3-二取代硫脲2a - k对黑色素瘤B16细胞株和蘑菇酪氨酸酶中黑色素形成的影响。1-苯基硫脲1a - k酪氨酸酶的抑制活性与其黑色素生成抑制作用平行。因此,1-苯基硫脲在黑色素瘤B16细胞中的黑色素生成抑制可能是酪氨酸酶抑制的结果。然而,1,3-二芳基或1-苯基-3-烷基硫脲,2a – k,表现为黑色素生成抑制剂,不抑制酪氨酸酶。1e和2b的分子对接研究到结合酪氨酸酶的口袋提供令人信服关于硫脲单元平面苯基的直接连接,而不的必要性解释N' 3'-取代苯基硫脲的1作为酪氨酸酶抑制剂和2作为非酪氨酸酶抑制剂。
