A series of 2-(1-phenylalkylidene)hydrazinecarbothioamides 2, 2-(1-phenylalkyl)hydrazinecarbothioamides 3, 2-(3,4-dihydronaphthalen-1(2H)-ylidene)hydrazinecarbothioamide (4), and 2-(1-(thiophen-2-yl)ethylidene)hydrazinecarbothioamide (5) were synthesized for their melanogenesis inhibition in melanoma B16 cells. The SAR of these ketonethiosemicarbazones revealed that the benzylidene hydrogen in ald
一系列2-(1- phenylalkylidene)的hydrazinecarbothioamides 2,2-(1-苯基烷基)hydrazinecarbothioamides 3,2-(3,4-二氢萘-1(2H) -亚基)肼硫代甲酰胺(4),和2-(1-合成了(噻吩-2-基)亚乙基)肼基碳硫代酰胺(5),以抑制其在黑素瘤B16细胞中的黑素生成。这些酮硫代半氨基甲酮的比吸收比(SAR)表明,醛基硫代半氨基甲酮1中的亚苄基氢可以被疏水部分取代并且被烷基取代为酮硫代半咪唑酮的末端氨基氢明显改善了活性。另外,硫代半氨基甲酮中的双键是增加疏水性的重要因素。因此,疏水性酮硫代半金属咔唑酮是优异的黑色素生成抑制剂,如乙醛硫代半金属咔唑酮。
