  the only aldose reductase inhibitor currently used in the therapy. Molecular docking analysis using the AR-NADP+ complex as a receptor was performed with all the synthesized compounds. All the compounds exhibit a well-defined binding mode within the AR active site, similarly to previous described AR inhibitors, with the anion head group bound to the catalytic center, blocking thus its activity. By forming

  醛糖还原酶的抑制剂是限速酶，可能在预防糖尿病并发症中起关键作用。在我们尝试开发醛糖还原酶的新型抑制剂的过程中，合成了若丹宁-3-马尿酸-吡唑杂化物的衍生物，并通过光谱数据对其进行了表征。生物学研究表明，所有化合物均显示出优异的抗ALR2活性，IC50值为0.04至1.36 µM。在这些合成的化合物6a-m，6g和6e中显示出对ALR2的特异性抑制活性，IC50值分别为0.04和0.06 µM，并被发现比当前使用的唯一醛糖还原酶抑制剂依帕司他（IC50 = 0.87μM）更有效。治疗。对于所有合成的化合物，均使用AR-NADP +配合物作为受体进行了分子对接分析。与先前描述的AR抑制剂相似，所有化合物在AR活性位点内均表现出明确的结合模式，其中阴离子头基键合至催化中心，从而阻断了其活性。通过与ALR2（PDB ID：2FZD）的蛋白质的Tyr48和His110形成氢键，化合物6g和6e中断了

  A series of new Schiff bases were synthesized by microwave assisted reactions of substituted 1-phenyl-1H-pyrazole-4-carbaldehyde and 2-aminophenol in ethanol and characterized by elemental analysis and spectroscopic (IR, 1H NMR and MS) data. The crystal structures of four compounds were studied using single-crystal XRD data. Molecular docking studies of all synthesized compounds were performed into the binding site of a protein 3GCW to gain comprehensive understanding into possible binding modes. These compounds were also screened for anticancer activity against the liver (HEP-G2) cell line using the sulphorhodamine-B assay method. Adriamycin i.e. doxorubicin was used as reference standard. One of the compounds shows anticancer activity close to the famous anticancer agent doxorubicin, which was used as control in this study. It is observed that all molecules show activity close to the standard in high concentrations only. Present study describes the anticancer activity and crystal structure study of Schiff bases of substituted pyrazole-4-carbaldehyde with 2-aminophenol. Docking study of all compounds against human hepatoma cell line, HEP-G2 correlates with in vitro activity.
