As a part of ongoing studies in developing new Tyrosinase inhibitors, a class of structurally novel 2-(2,4-dimethoxy phenylamino)-5 methylene-4-thiazolinone derivatives were synthesized by incorporating 2-(2,4-dimethoxy-phenylamino)-thiazol-4-one with various 1-(1-methyl-buta-1,3-dienyl)-3-phenyl-1H-pyrazole-4-carbaldehyde. The results showed that some of the synthesized compounds exhibited significant
作为开发新型酪氨酸酶抑制剂的正在进行研究的一部分,通过结合2-(2,4-二甲氧基-苯基氨基)合成了一类结构新颖的2-(2,4-二甲氧基苯基氨基)-5亚甲基-4-噻唑啉酮衍生物。 -噻唑-4-酮与各种1-(1-甲基-丁基-1,3-二烯基)-3-苯基-1 H-吡唑-4-甲醛。结果表明,某些合成的化合物表现出显着的抑制活性。特别是5- [3-(2-氯-苯基)-1-苯基-1 H-吡唑-4-基亚甲基] -2-(2,4-二甲氧基-苯基氨基)-噻唑-4-酮(5h)和5- [3-(3-氯-苯基)-1-苯基-1 H-吡唑-4-基亚甲基] -2-(2,4-二甲氧基-苯基氨基)-噻唑-4-酮(5g)具有2-氯-苯基和3-氯-苯基的)表现出最强的酪氨酸酶抑制活性,IC 50值分别为34.12和52.62μM。5h和5g噻唑烷酮衍生物的抑制机理分析表明,该化合物对酪氨酸酶的抑制作用是可逆的和竞争性的。初步的结构-活
