摘要:
最近被靶向的Pim-1激酶已被证明是乳腺癌治疗的基本目标。我们报告设计,合成与针对Pim-1激酶作为抗乳腺癌药物的吡唑并[3,4- b ]吡啶支架基衍生物的全表征分析。筛选所有新合成的化合物对两种乳腺癌细胞系MCF-7和MDA-MB-231以及非癌MCF-10A细胞的体外细胞毒活性。值得注意的是,四种衍生物17和19对IC 50表现出显着的细胞毒性活性对MCF-7(ERα依赖性)细胞有选择性的5.98和5.61 µM值,因为它们对MDA-MB-231(非ERα依赖性)没有活性,对MCF-10A安全。通过体外筛选,将最具活性的化合物置于PIM-1激酶下,以阐明Pim-1激酶的抑制活性是其作用机理。在测试的衍生物中,与IC 50值为17 nM的5-FU相比,化合物17和19的抑制活性最高,IC 50值为43和26 nM。此外,通过流式细胞术进行凋亡研究以及针对MCF-7活性最高的化合物19的凋

(PPHC–nSiO2), was prepared and characterized by FT-IR, TGA, SEM and ICP techniques. The resulting catalyst was used for the efficient synthesis of fully substitutedpyridines via a one-pot multicomponent reaction of aldehydes, malononitrile, and thiols under solvent-free conditions. Expedient synthesis of bis-pyridines from dialdehydes and/or dithiols by using this catalytic system can be considered
制备了一种新型的负载型based基离子液体,载于纳米二氧化硅(PPHC- n SiO 2)上的碳酸氢丙propyl离子液体,并通过FT-IR,TGA,SEM和ICP技术进行了表征。通过在无溶剂条件下醛,丙二腈和硫醇的一锅多组分反应,将所得催化剂用于有效合成全取代的吡啶。通过使用该催化体系由二醛和/或二硫醇方便地合成双吡啶可被认为是该方法的显着优点。此外,即使在第5个循环后也没有明显的催化活性损失。

2-Hydroxyethylammonium sulphonate immobilized on gamma-Fe2O3 nanoparticles (gamma-Fe2O3-2-HEAS) was synthesized as a new supported ionic liquid by the reaction of n-butylsulfonated gamma-Fe2O3 with ethanolamine. It was used as a magnetically recyclable heterogeneous catalyst for the efficient one-pot, three-component synthesis of 2-amino-3,5-dicarbonitrile-6-thio-pyridines. The catalyst was easily isolated from the reaction mixture by magnetic decantation using an external magnet and reused at least five times without significant degradation in the activity.
