Inhibition of the PCAF histone acetyl transferase and cell proliferation by isothiazolones
摘要:
Small molecule HAT inhibitors are useful tools to unravel the role of histone acetyl transferases (HATs) in the cell and have relevance for oncology. We present a systematic investigation of the inhibition of the HAT p300/CBP Associated Factor (PCAF) by isothiazolones with different substitutions. 5-chloroisothiazolones proved to be the most potent inhibitors of PCAF. The growth inhibition of 4 different cell lines was studied and the growth of two cell lines (A2780 and HEK 293) was inhibited at micromolar concentrations by 5-chloroisothiazolones. Furthermore, the 5-chloroisothiazolone preservative Kathon (TM) CG that is used in cosmetics inhibited PCAF and the growth of cell lines A2780 and HEK 293, which indicates that this preservative should be applied with care.

The present disclosure generally relates to pharmaceutical compositions and combinations comprising an androgen receptor N-terminal domain inhibitor or an inhibitor and a second therapeutically active agent, such as an CDK4/6 inhibitor, a Pin1 inhibitor (inhibitor of peptidyl-prolyl cis/trans isomerases), or an antiandrogen. In particular, the present disclosure relates to pharmaceutical compositions and combintaions useful for treatment of various cancers, for example breast cancer and prostate cancer. Further, the present disclosure relates administering an androgen receptor N-terminal domain inhibitor in combination with radiation therapy for treatment of various cancers.
