Synthesis and potent cytotoxicity of some novel imidazopyridine derivatives against MCF-7 human breast adenocarcinoma cell line
摘要:
A series of novel 2-phenyl-3H-imidazo[4,5-b]pyridines and 2-phenyl-3H-imidazo[4,5-c]pyridines and their precursors were synthesized. Their in vitro cytotoxicity against MCF-7 human breast adenocarcinoma cell line has been investigated, and some of the tested compounds have shown high cytotoxic activity against MCF-7 cells. N-Hydroxy-4-(3H-imidazo[4,5-b]pyridin-2-yl)benzenecarboximidamide was the most active compound with IC50 equal to 0.082 mu M, which is an activity almost as high as that of a commonly used anticancer drugs docetaxel and imatinib mesylate.

Abstract The reactions of substituted o-phenylene diamines, o-aminophenol, o-aminothiophenol, 3,4-diaminopyridine with p-cyanobenzaldehyde by refluxing in nitrobenzene gave corresponding benzimidazole, benzoxazole, benzthiazole and imidazopyridine derivatives Ia,b, II, III, and IV, respectively. Reaction of 4,5-diaminopyrimidine with p-cyanobenzaldehyde gave only Schiffs base it. V or V′ and not imidazopyrimidine
Synthesis and antiviral activity of new phenylimidazopyridines and N-benzylidenequinolinamines derived by molecular simplification of phenylimidazo[4,5-g]quinolines
assays for cytotoxicity and antiviralactivityagainst representatives of two DNA virus families as wells as against representatives of RNA virus families containing single-stranded, either positive-sense (ssRNA+) or negative-sense (ssRNA−), and double-stranded genomes (dsRNA). Some imidazo[4,5-b]pyridines emerged as new derivatives endowed with antiviralactivityagainst Vaccinia Virus (VV) at concentrations
继续进行有关一系列新的角和线性偶氮双环和三环衍生物的抗病毒活性的研究计划,现在我们简化并修饰了4-氯-2-(4-硝基苯基)-3 H-咪唑[4,通过消除中心环或咪唑环的打开,先前产生活性最高的衍生物的5- g ]喹啉1分别获得各种咪唑并吡啶和N-亚苄基喹啉胺。 标题化合物中的细胞毒性和抗病毒活性对两个DNA病毒科的代表,孔中作为对含有单链,无论是正链(单链RNA的RNA病毒科的代表基于细胞的测定中测试+)或负义单链RNA(-)和双链基因组(dsRNA)。一些咪唑并[4,5- b ]吡啶以新衍生物的形式出现,在2至16μM的浓度范围内具有抗痘苗病毒(VV)的抗病毒活性。特别是,化合物2b的功效比用作参考药物的西多福韦强约10倍。同样,咪唑并[4,5- c ]吡啶和N-亚苄基喹啉胺衍生物在1.2至28μM的浓度范围内具有抗牛病毒性腹泻病毒(BVDV)的活性。所有上述化合物1,图3a和3f中显示出EC
