Novel ibuprofen derivatives 1–19 including ibuprofen hydrazide 1, and substituted thiourea derivatives 2–19 were synthesized and characterized by EI-MS, FAB-MS, HREI-MS, HRFAB-MS, 1H-, and 13C-NMR spectroscopic techniques. The synthetic molecules 1–19 were examined for their in vitro urease inhibition and were found to display a diversified degree of inhibitory potential in the range of IC50 = 2.96–178 μM as compared to the standard thiourea (IC50 = 21.32 ± 0.22 μM). Out of nineteen, thirteen derivatives 2–4, 6, 7, 9, 11–15, 17, and 18 demonstrated remarkable inhibitory activity with IC50 values of 2.96 ± 1.11 to 16.1 ± 1.07 μM, compound 5 exhibited moderate inhibition with IC50 value of 37.3 ± 0.41 μM, whereas, compounds 1, 8, and 10 demonstrated weak inhibition against urease enzyme. Almost all structural features are participating in the activity; however, limited structure–activity relationship was discussed on the basis of different structural features, i.e., different functional groups and their positions at aryl part. In addition, molecular docking study was performed in order to understand the ligands binding interactions with the active site of urease enzyme.
通过 EI-MS、FAB-MS、HREI-MS、HRFAB-MS、1H 和 13C-NMR 光谱技术合成了新型布洛芬衍生物 1-19,包括布洛芬酰肼 1 和取代的硫脲衍生物 2-19。与标准硫脲(IC50 = 21.32 ± 0.22 μM)相比,合成分子 1-19 在 IC50 = 2.96-178 μM 的范围内显示出不同程度的抑制潜力。在 19 种衍生物中,13 种衍生物 2-4、6、7、9、11-15、17 和 18 具有显著的抑制活性,IC50 值为 2.96 ± 1.11 至 16.1 ± 1.07 μM ;化合物 5 具有中等程度的抑制作用,IC50 值为 37.3 ± 0.41 μM ;而化合物 1、8 和 10 对脲酶具有微弱的抑制作用。几乎所有的结构特征都参与了活性;然而,根据不同的结构特征,即不同的官能团及其在芳基部分的位置,讨论了有限的结构-活性关系。此外,还进行了分子对接研究,以了解配体与脲酶活性位点的结合相互作用。
