Ongoing effort to gather further knowledge about the structural requirements on histone deacetylase inhibitors led to the synthesis of novel N-hydroxybenzamide-based HDAC inhibitors 1a-o, introducing branched hydrophobic groups at the capping group, and their inhibition activity against HDACs and anti-proliferation activity in four tumor cell lines were determined. Compounds 1j-o were further tested against recombinant human HDAC1 and HDAC4 to evaluate their selectivity profile. This work further suggests that the chemical nature of the capping group is critical for subtle discrimination between the class I and the class II HDAC isoforms.

A novel series of N-hydroxy-4-(3-phenylpropanamido)benzamide (HPPB) derivatives comprising N-hydroxybenzamide group as zinc-chelating moiety were designed, synthesized and evaluated as histone deacetylases inhibitors. The thiophene substituted derivative 5j exhibited the best HDAC inhibition activity among these compounds. The present study was designed to evaluate the efficacy of 5j as a candidate compound for cancer therapy. Our results indicated that 5j exhibited better HDAC1, 8 and hela nuclear extract inhibition activities than SAHA, and good antiproliferative activities against a broad spectrum of human cancer cell lines especially for breast cancer. 5j induced cell cycle arrest at G(2)/M phase, and eventual apoptosis possibly by modulating p21, caspase-3 and Bcl-x(L) on MDA-MB-231 cells. In addition, 5j down regulated the active form of MMP2, and inhibited the invasion of MDA-MB-231 cell lines. Moreover, 5j significantly delayed the growth of MDA-MB-231 xenografts in mice after 3 weeks of peritoneal injection. In summary, our results suggest that 5j might have therapeutic potential for the treatment of human breast cancer.
