Histone Deacetylase (HDAC) inhibitors are a new class of therapeutic compounds that show promising results in a series of preclin. and clin. anticancer studies. Hydroxamic acids belong to one of the most significant classes of HDAC inhibitors. The member vorinostat (SAHA) was approved by the U. S. Food and Drug Administration for the treatment of cutaneous T-cell lymphoma. A series of eight novel hydroxamic acids containing 2-imidazolylphenyl(oxy/thio) alkanoic fragment designed to target Histone Deacetylase (HDAC) were synthesized in five steps from easily accessible 2(3H)-benzoxazolones and 2(3H)-benzthiazolones. The newly synthesized compounds were characterized by 1H, 13C NMR, and elemental anal. The structure-activity relationship was examined via linker length alternation and variation of the heteroatom (oxygen or sulfur) and chlorine substitution pattern of the starting materials. The compounds were tested for their cytotoxic activity against two human cancer cell lines (HT-29 and MDA-MB-231). Our data indicate that the compound 6.1d is active in the micromolar range with IC50 of 9.7 μM for MDA-MB-231 cells. DNA fragmentation anal. of the most active compounds confirmed that apoptosis could be one of the mechanisms involved in cell death. Taken together, the results revealed that 6d may become a promising lead compound for new anticancer drugs discovery. In the experiment, the researchers used Ethyl 4-bromobutyrate(cas: 2969-81-5Synthetic Route of C6H11BrO2)
Ethyl 4-bromobutyrate(cas: 2969-81-5) belongs to bromides. Most organobromine compounds, like most organohalide compounds, are relatively nonpolar. Bromine is more electronegative than carbon (2.9 vs 2.5). Consequently, the carbon in a carbon–bromine bond is electrophilic, i.e. alkyl bromides are alkylating agents.Synthetic Route of C6H11BrO2
