non-competitive mode of inhibition for compound 3j. Moreover, in silico molecular docking against target protein (PDBID 4H9M) indicated that most of the synthesized compounds exhibit good binding affinity with protein. The compound 3j forms two hydrogen bonds with amino acid residue VAL391 having a binding distance of 1.858 Å and 2.240 Å. The interaction of 3j with amino acid residue located outside the catalytic
本文描述了一系列作为杰克豆脲酶抑制剂的新型金刚烷胺-硫脲偶联物 ( 3a – j ) 的设计和合成。测定合成的杂种的体外脲酶抑制。因此,具有7个碳烷基链的N- (adamantan-1-ylcarbamothioyl)octanamide ( 3j )表现出优异的活性,IC 50值为0.0085 ± 0.0011 µM,表明长烷基链在酶抑制中起重要作用。而具有 2-氯苯基取代的N -(adamantan-1- ylcarbamothioyl )-2-chlorobenzamide ( 3g ) 是属于芳基系列的下一个最有效的化合物,IC 50值为 0.0087 ± 0.001 µM。Lineweaver-Burk 图分析的动力学机制揭示了化合物3j的非竞争性抑制模式。此外,针对靶蛋白(PDBID 4H9M)的计算机分子对接表明,大多数合成的化合物与蛋白质表现出良好的结合亲和力。化合物3j与氨基酸残基
