Аннотация
A series of novel 2-(4-phenoxyphenyl)-1H-benzimidazole derivatives was synthesized and tested in vitro on human chronic myelogenous leukemia (CML) cell line K562. Benzimidazoles containing 5-amidino (10), 5-N-isopropylamidino (11), 5-bromo (13), and 5,6-dimethyl (14) derivatives exhibited remarkable cytotoxic activity. The quantitative analysis of apoptosis by flow-cytometry demonstrated that the percentages of early and late apoptotic K562 cells treated with these compounds were significantly higher than cells without treatment. We also investigated the effects of these compounds on the expression of apoptosis-related genes BAX, BCL-2, BAD and BIM. Treatment of K562 cells wih compounds 10-14 significantly increased the expression levels of the proapoptotic genes BAX, BAD and BIM, whereas compound 20 increased BAX and BAD.
