The synthesis and biological evaluation of a variety of 4-piperazinyl-containing Chidamide derivatives is described. Some of these compounds were shown to inhibit HDAC1 with IC50 values below micromolar range, and inhibited proliferation of several human cancer cells, not possessing toxicity to human normal cells and hERG K+ ion channels. Compound 9g, proved to be the most potent and efficacious derivative in this series, was orally active in an HCT116 xenograft model in vivo. |
