A multi-step synthesis of novel bi-heterocyclic N-arylated butanamides was consummated through a convergent strategy and the structures of these medicinal scaffolds, 7a–h, were corroborated using spectral techniques. The in vitro analysis of these hybrid molecules revealed their potent tyrosinase inhibition as compared to the standard used. The kinetics mechanism was investigated through Lineweaver-Burk
通过收敛策略完成了新型双杂环N-芳基化丁酰胺的多步合成,并使用光谱技术证实了这些药用支架7a–h的结构。与所用标准相比,这些杂合分子的体外分析揭示了它们有效的酪氨酸酶抑制作用。通过 Lineweaver-Burk 图研究了动力学机制,该图显示7f通过形成酶-抑制剂复合物非竞争性地抑制酪氨酸酶。从该化合物的 Dixon 图计算出的抑制常数 K i为 0.025 μM。它们的结合构象是通过in silico确定的计算研究表明这些分子具有良好的结合能值 (kcal/mol)。因此,从目前的研究中可以预期,这些双杂环丁酰胺可能被探索为黑色素生成的必要治疗剂。
