HDAC inhibitor (HDACi) is used in therapy: suberoylanilide hydroxamic acid (SAHA). Here, we describe the synthesis and biological evaluation of a new series of compounds derived from SAHA by substituting short alkyl chains at various positions of the phenyl ring. Such modifications induced variable effects ranging from partial loss of activity to increased potency. Through molecular modeling, we describe
组蛋白脱乙酰基酶(HDACs)的抑制导致肿瘤细胞系的生长停滞,分化或凋亡,这表明HDACs是癌症治疗的有希望的靶标。目前,只有一种HDAC抑制剂(HDACi)用于治疗:磺酰苯胺异羟肟酸(SAHA)。在这里,我们描述了由SAHA衍生的一系列新化合物的合成和生物学评估,方法是通过在苯环的各个位置上取代短烷基链。这种修饰引起可变的作用,其范围从活性的部分丧失到效力的增加。通过分子建模,我们描述了HDAC7脯氨酸809(仅在第2类酶中严格保守的残基)与HDACi的酰胺基团之间的可能相互作用,而核磁共振实验表明,二甲基m-取代可以使抑制剂稳定在活性位点。我们的数据提供了有关HDACi的结构活性关系的新颖信息,并提出了开发第二代SAHA样分子的新方法。
