Synthesis, Antimicrobial, Antioxidant and Docking Study of Some Novel 3,5-Disubstituted-4,5-dihydro-1H-pyrazoles Incorporating Imine Moiety
摘要:
A NOVEL series of 3,5-Disubstituted-4,5-Dihydro-1H-pyrazoles (3-9) containing imine moiety were synthesized and characterized using spectral analysis. The synthesized derivatives were In vitro screened against several bacterial species, Staphylococcus aureus, Pseudomonas aeruginosa and Acinetobacterbaumannii as well as Candida albicans and revealed moderate to potent activity. The antioxidant study was confirmed for the synthesized derivatives against 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical qualitatively using TLC technique, and quantitatively by spectrophotometric method. The half maximal inhibitory concentration (IC50) was calculated for the active compounds (1-5, 8). Docking study for the potent compounds (2 and 4) against glucosamine-6-phosphate synthase, the target enzyme for the antimicrobial agents, was explored to explain the interactions of the discovered hits within the amino acid residues of the enzyme active side. The docking parameters enhanced the activity of new compounds as promising antimicrobial agents.
合成了一系列吡唑啉衍生物,并通过IR,1 H NMR,13 C NMR,质谱和元素分析对它们的结构进行了表征。该新化合物被设计为结核分枝杆菌iki酸酯激酶(MtSK)抑制剂基于使用Sybyl-X 2.0软件的对接研究。在计算机模拟中ADMET的预测表明,所有化合物均具有最小的毒性作用,并具有良好的吸收性和溶解性。因此,这些化合物可作为开发新的抗结核药物的潜在先导化合物。在测试的化合物4c,5b和6a中,它们显示出有希望的抗结核活性。另外,还使用色氨酸蓝排除法评估了某些化合物对EAC细胞系的细胞毒活性。
