5-arylmethylidene fragment than on the 2-aryl ring in general. The cytotoxicities of the synthesized compounds were lower than those of the previously reported isomeric 2-aryl-4-benzoyl-imidazoles, and the basic structure–activity relationships in the isomeric pairs were different. Synthesized (5Z)-5-[(4-bromophenyl)methylidene]-2-(4-methylphenyl)-3,5-dihydro-4H-imidazol-4-one, which had the highest cytotoxicity
与细胞蛋白微管蛋白和微管相互作用的化合物是抗有丝分裂剂的一种重要类型。据报道,一系列针对微管蛋白的2-芳基-4-苯甲酰基-咪唑具有很高的细胞毒性,因此,我们制备了一系列结构异构体,以作为抗有丝分裂剂进行评估。新型(Z)-2-芳基-5-芳基亚甲基-3,5-二氢-4 H的合成-咪唑-4-酮涉及取代的马尿酸与芳族醛的偶联。随后在尿素和乙酸铵存在下在微波辐射下将所得的恶唑酮转化为相应的咪唑酮。大多数化合物对人上皮癌细胞系A549的细胞毒性在亚微摩尔范围内,并且发现其对5-芳基亚甲基片段上的取代基的敏感性比通常对2-芳基环上的更为敏感。合成的化合物的细胞毒性低于以前报道的异构体2-芳基-4-苯甲酰基-咪唑,并且这些异构体对中的基本结构-活性关系不同。合成(5 Z)-5 - [(4-溴苯基)亚甲基] -2-(4-甲基苯基)-3,5-二氢-4- ħ -咪唑-4-酮,它具有最高的细胞毒性(IC 50 〜
