继续我们对合成具有预期生物活性特别是抗肿瘤活性的新型杂环的兴趣。在本文中,我们讨论了1,3-二苯基吡唑-4-甲醛4与苯乙酮衍生物1a-d,活性亚甲基化合物,肼和苯胺衍生物的合成和反应,以产生预期的衍生物5a-d。另外,在三乙胺的催化下,通过1,3-二苯基吡唑-4-甲醛1,丙二腈和硫醇衍生物13a-e的一锅三组分环缩合反应,合成了一系列五取代的吡啶衍生物15a-e。 。另外,由N-((1,3-二苯基-1H-吡唑)合成了2-(1,3-二苯基-1H-吡唑-4-基)-3-(芳基)噻唑烷-4-one 20a-e。 -4-基)亚甲基苯胺衍生物11a-e和巯基乙酸。筛选了一些合成的衍生物的抗肿瘤活性。所有新合成的化合物均已通过元素分析,IR,1 H NMR,13 C NMR,MS进行了表征,并在某些情况下通过与化合物的已知特性进行比较或与通过报告明确的路线制备的样品进行比较。

A series of 16 novel spirooxindole analogs 8a–p were designed and constructed via cost-effective single-step multicomponent [3+2] cycloaddition reaction of azomethine ylide (AY) generated in situ from substituted isatin (6a–d) with suitable amino acids (7a–c) and ethylene-engrafted pyrazole derivatives (5a,b). The potency of all compounds was assayed against a human breast cancer cell line (MCF-7)
Ultrasound-assisted ionic liquid-mediated green method for synthesis of 1,3-diphenylpyrazole-based spirooxindolopyrrolizidines, their anti-tubercular activity, molecular docking study and ADME predictions
in vitro anti-TB activity against Mycobacterium tuberculosis H37Rv strain. Among all, six compounds 4e (C36H29N5O4), 4g (C34H28N4O3), 4q (C36H28F2N4O2), 4r (C36H28ClFN4O2), 4y (C36H29BrN4O2) and 4z (C36H28BrFN4O2) exhibited significant anti-TB activity with MIC value 6.25 μg mL−1, when compared to the standard drug ethambutol (MIC:1.56 μg mL−1). In silico molecular dockingstudies were performed against
本研究的目的是通过使用离子液体 ([Bmim] BF 4 )在超声处理下。标题化合物4a – 4ad的通式为 C a H b X (0–2) N c O d (X = F/Cl/Br),可以在更短的反应时间内以高产率生产,并通过使用光谱技术进行了很好的表征;最后是单晶X射线衍射法( 4b )。评估了新合成的化合物对结核分枝杆菌H37Rv 菌株的体外抗结核活性。其中,6个化合物4e (C 36 H 29 N 5 O 4 )、4g (C 34 H 28 N 4 O 3 )、4q (C 36 H 28 F 2 N 4 O 2 )、4r (C 36 H 28 ClFN 4 O 2 )、4y (C 36 H 29 BrN 4 O 2 )和4z (C 36 H 28 BrFN 4 O 2 )与标准药物乙胺丁醇相比表现出显着的抗结核活性,MIC值为6.25 μg mL -1 。 (MIC:1.56μg·mL
