Abstract

The combretastatin A‑4/oltipraz hybrid (COH), 5‑(3‑amino‑­4‑methoxyphenyl)‑4‑(3,4,5‑trimethoxyphenyl)‑3H‑1,2‑dithiole‑3‑one (COH‑203) is one of the COH compounds synthesized by our previous study, which has been reported to affect a number of cancer cell lines, such as SGC‑7901, KB, HT‑1080, HepG2, SMMC‑7721 and BEL‑7402. The sensitivity of human acute leukemia cell lines to COH‑203, and the mechanism underlying its anti‑proliferative effects remain unknown, which was investigated in the present study. In the present study, it was demonstrated that COH‑203 had notable time‑ and dose‑dependent antiproliferative effects on the human acute promyelocytic leukemia HL‑60 cell line. Furthermore, COH‑203 treatment resulted in cell cycle arrest at G2/M phase in a dose‑dependent manner, and subsequently induced apoptosis. Western blot analysis revealed that upregulation of cyclin B was associated with G2/M arrest. In addition, treatment with COH‑203 resulted in downregulated expression of Bcl‑2. This result revealed that COH‑203‑induced apoptosis in HL‑60 cells may occur via the mitochondrial pathway in a caspase‑dependent manner.
