AbstractIn the presented work, a new series of three different 4‐((3,5‐dichloro‐2‐[(2/4‐halobenzyl)oxy]phenyl)sulfonyl)morpholines was synthesized and the structure of these compounds were corroborated by 1H‐NMR & 13C‐NMR studies. The in vitro results established all the three compounds as potent tyrosinase inhibitors relative to the standard. The Kinetics mechanism plots established that compound 8 inhibited the enzyme non‐competitively. The inhibition constants Ki calculated from Dixon plots for this compound was 0.0025 μM. Additionally, computational techniques were used to explore electronic structures of synthesized compounds. Fully optimized geometries were further docked with tyrosinase enzyme for inhibition studies. Reasonably good binding/interaction energies and intermolecular interactions were obtained. Finally, drug likeness was also predicted using the rule of five (RO5) and Chemical absorption, distribution, metabolism, excretion, and toxicity (ADMET) characteristics. It is anticipated that current experimental and computational investigations will evoke the scientific interest of the research community for the above‐entitled compounds.
摘要 在本研究中,合成了三个不同的 4-((3,5-二氯-2-[(2/4-卤苄基)氧基]苯基)磺酰基)吗啉新系列,并通过 1H-NMR & 13C-NMR 研究证实了这些化合物的结构。体外实验结果表明,与标准化合物相比,这三种化合物都是有效的酪氨酸酶抑制剂。动力学机制图表明,化合物 8 对酶具有非竞争性抑制作用。根据 Dixon 图计算出的该化合物的抑制常数 Ki 为 0.0025 μM。此外,还利用计算技术探索了合成化合物的电子结构。完全优化的几何结构进一步与酪氨酸酶对接,进行抑制研究。结果表明,这些化合物具有良好的结合/相互作用能和分子间相互作用。最后,还利用五则运算(RO5)和化学吸收、分布、代谢、排泄和毒性(ADMET)特征预测了药物的相似性。预计目前的实验和计算研究将唤起研究界对上述化合物的科学兴趣。
