In vitro study | Treatment of cell lines from a variety of solid tumors with the combination of ACY-241 and paclitaxel can enhance the inhibition of cell proliferation. Compared with the single drug treatment, the combination treatment can also increase cell death, it also leads to abnormal Multipolar spindles and abnormal mitosis in dividing cells, which is associated with the formation of abnormal Multipolar spindles, induction of aneuploidy and increased cell death. In A2780 ovarian cancer cells, α-tubulin was highly acetylated and tubulin deacetylase HDAC6 was inhibited after 24 hours of 300 nM ACY-241 treatment. A low concentration of ACY-241 can selectively inhibit HDAC6, while a high concentration will result in inhibition of the class I HDAC isoenzyme. |
