HDAC inhibitors has been hampered by lack of efficient enzyme assays, in the preceding paper two assays have been developed to improve the efficiency of these enzymes: mutating an active site histidine to tyrosine, or by the use of a trifluoroacetamide lysine substrate, allowing screening to identify class II HDAC inhibitors. Herein, 2-trifluoroacetylthiophenes have been demonstrated to inhibit class
II类HDAC抑制剂的鉴定因缺乏有效的酶检测而受阻,在前一篇论文中,开发了两种检测以提高这些酶的效率:将活性位点组氨酸突变为酪氨酸,或使用三氟乙酰胺赖氨酸底物,可进行筛选以鉴定II类HDAC抑制剂。在本文中,已经证明2-三氟乙酰基噻吩抑制II类HDAC,从而导致开发出一系列5-(三氟乙酰基)噻吩-2-甲酰胺,它们是新颖的,有效的和选择性的II类HDAC抑制剂。具有结合的抑制剂的HDAC 4催化域的X射线晶体结构表明,这些化合物是活性位点抑制剂,并以其水合形式结合。
