Naphthalimide-benzimidazole conjugates were prepared using two different types of spacer
units; either a simple alkane chain or a substituted piperazine moiety with variable alkyl side chains.
Each set of conjugates was evaluated for their in vitro anticancer activity, and compounds 14a, 14b
and 20c were found to exhibit significant activity against a number of cancer cell lines. In particular,
compound 14a showed remarkable anticancer activity with GI50 values of 0.02 μM and 0.49 μM
against central nervous system (SNB-75) and leukemia (K-562) cell lines, respectively. Compound
14b showed noticeable activity against melanoma (MAME-3M) cell line with GI50 value 0.09 μM.
Compound 20c also displayed selectivity against leukemia cell lines with GI50 values up to 0.21 μM as
well as appreciable broad-spectrum cytotoxicity.
萘咪唑-苯并咪唑缀合物使用两种不同类型的间隔单元制备;一种是简单的烷烃链,另一种是具有可变烷基侧链的取代哌嗪基团。每组缀合物的体外抗癌活性进行了评估,化合物14a、14b和20c发现对多种癌细胞系表现出显著活性。特别是化合物14a在中枢神经系统(SNB-75)和白血病(K-562)细胞系中分别显示出0.02 μM和0.49 μM的显著抗癌活性。化合物14b在黑色素瘤(MAME-3M)细胞系中显示出明显活性,GI50值为0.09 μM。化合物20c对白血病细胞系也表现出选择性,GI50值高达0.21 μM,并且具有良好的广谱细胞毒性。
