设计并合成了两个系列的新型2-芳基乙烯基萘[2,3- d ]咪唑-3-溴化碘衍生物和2-芳基乙烯基萘[2,3 - d ]咪唑-3-溴化碘衍生物。YM155与类胡萝卜素的组合。测试所有化合物对PC-3,A375和HeLa人癌细胞系的抗增殖活性。选择了两种化合物进行进一步研究:12b,对三种测试的细胞系均表现出强大的细胞毒性,IC 50值在0.06-0.21μM范围内,而7l对具有IC的PC-3细胞显示出优异的选择性仅22 nM中的50。蛋白质印迹分析结果表明,两种12b7l和7l抑制Bcl-2和Survivin蛋白的表达,有助于诱导细胞凋亡。如膜联蛋白V-FITC阳性凋亡细胞的百分比所确定,在PC-3细胞中浓度为100 nM时,12b不仅比7l更有效,而且还以剂量依赖性方式诱导细胞凋亡,效力高于7l。在A375细胞中浓度为1000 nM。因此,选择化合物12b用于进一步深入研究以研究细胞凋亡

Here we report the nanomolar potencies of N 1,N 3-dialkyldioxonaphthoimidazoliums against asexual forms of sensitive and resistant Plasmodium falciparum. Activity was dependent on the presence of the fused quinone-imidazolium entity and lipophilicity imparted by the N1/N3 alkyl residues on the scaffold. Gametocytocidal activity was also detected, with most members active at IC50 < 1 μM. A representative
This invention relates to medicaments, particularly novel fused imidazolium derivatives useful for the treatment of cancers and novel synthetic intermediate compounds thereof.
The novel imidazolium derivatives fused with an aryl or heteroaryl ring, characterized in that the 1- and/or 3-position is substituted by an alkyl group etc. having a substituent selected from the group consisting of —OR
