Anticancer agent 71 (Compound 4b) is a potent anticancer agent. Anticancer agent 71 arrests cell cycle at G2/M phase. Anticancer agent 71 induces apoptosis through upregulating Bax, Ikb-α and cleaved PARP and downregulating Bcl-2 expression levels.

Anticancer agent 71 (Compound 4b) (0.1-50 μM, 24 hours; SW480 and PC3 cells) increases the cytotoxicity and exerts potent antitumor activities against SW480 and PC3 cells [1]. Anticancer agent 71 (Compound 4b) (11.08 μM, 24 hours; SW480 cells) induces a significant G2/M phase arrest [1]. Anticancer agent 71 (Compound 4b) (11.08 μM, 24 hours) induces apoptosis in SW480 cells by upregulating Bax, Ikb-α and cleaved PARP and downregulating Bcl-2 expression [1]. Cell Cytotoxicity Assay [1] Cell Line: SW480 and PC3 cells Concentration: 0.1, 1, 12.5, 25 and 50 μM Incubation Time: 24 hours Result: Inhibited with IC 50 values of 11.08 and 17.39 μM for SW480 and PC3 cells, respectively. Cell Cycle Analysis [1] Cell Line: SW480 cells Concentration: 11.08 μM Incubation Time: 24 hours Result: The cell population percent at G2/M phase increased to 45.3%. Apoptosis Analysis [1] Cell Line: SW480 cells Concentration: 11.08 μM Incubation Time: 24 hours Result: The percentage of cells in early and late apoptosis was recorded as 5.69% and 3.52%, respectively. Western Blot Analysis [1] Cell Line: SW480 cells Concentration: 11.08 μM Incubation Time: 24 hours Result: The expression of antiapoptotic protein Bcl-2 decreased and the expression of Pro apoptotic Bax increased.
