Title: Inhibition of the PCAF histone acetyl transferase and cell proliferation by isothiazolones.
Authors: Dekker FJ, Ghizzoni M, van der Meer N, Wisastra R, Haisma HJ.
Abstract: 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 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.
