A convenient synthesis of 1-thiocarbamoyl-3-phenyl-5-diphenyl-4,5-dihydro-(1H)-pyrazole derivatives (2a-2g) was carried out by the condensation reaction of (E)-3-(phenyl)-1-(biphenyl-2-yl)-3-arylprop-2-en-1-ones (1a-1g) with thiosemicarbazide, sodium hydroxide as a catalyst in the presence of ethanol as solvent. Further, (E)-3-(phenyl)-1-(biphenyl-2-yl)-3-arylprop-2-en-1-ones were synthesized by the Claisen-Schmidt condensation reaction of substituted aldehydes with 4-acetylbiphenyl in the presence of basic ethanolic solution. The structure of synthesized compounds were confirmed by FT-IR, 1H NMR, 13C NMR and 1H-1H COSY. The antimicrobial susceptibility tests of synthesized compounds were screened against Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli and Pseudomonas aeruginosa. The docking studies also carried out by using 1UAG receptor for all the synthesized compounds (2a-2g).
通过(E)-3-(苯基)-1-(联苯-2-基)-3-芳基丙-2-烯-1-酮(1a-1g)与硫脲的缩合反应,以氢氧化钠为催化剂,乙醇为溶剂,进行了一种便捷的1-硫代氨基甲酰基-3-苯基-5-二苯基-4,5-二氢-(1H)-吡唑衍生物(2a-2g)的合成。此外,(E)-3-(苯基)-1-(联苯-2-基)-3-芳基丙-2-烯-1-酮是通过取代的醛与4-乙酰基联苯在碱性乙醇溶液中的Claisen-Schmidt缩合反应合成的。通过FT-IR、1H NMR、13C NMR和1H-1H COSY确认了合成化合物的结构。对合成化合物进行了抗菌敏感性测试,针对金黄色葡萄球菌、酿脓链球菌、大肠杆菌和铜绿假单胞菌进行了筛选。通过使用1UAG受体对所有合成化合物(2a-2g)进行了对接研究。
