In an effort to identify HDAC isoform selective inhibitors, we designed and synthesized novel, chiral 3,4-dihydroquinoxalin-2(1H)-one and piperazine-2,5-dione aryl hydroxamates showing selectivity (up to 40-fold) for human HDAC6 over other class I/IIa HDACs. The observed selectivity and potency (IC50 values 10–200 nM against HDAC6) is markedly dependent on the absolute configuration of the chiral moiety
为了鉴定HDAC同工型选择性抑制剂,我们设计并合成了新颖的,手性的3,4-二氢喹喔啉-2(1 H)-one和哌嗪-2,5-二酮芳基异羟肟酸酯,它们显示出对HDAC的选择性(高达40倍)人类HDAC6优于其他I / IIa类HDAC。观察到的选择性和效价(针对HDAC6的IC 50值为10–200 nM)明显取决于手性部分的绝对构型,这表明在选择性HDAC同工型抑制中使用手性化合物的新可能性。
