Class I histone deacetylases, HDAC1, HDAC2, and HDAC3, represent potential targets for cancer treatment. However, the development of isoform-selective drugs for these enzymes remains challenging due to their high sequence and structural similarity. In the current study, we applied a computational approach to predict the selectivity profile of developed inhibitors. Molecular docking followed by MD simulation
I 类组蛋白去乙酰化酶 HDAC1、HDAC2 和 HDAC3 代表了癌症治疗的潜在目标。然而,由于它们的高度序列和结构相似性,为这些酶开发异构体选择性药物仍然具有挑战性。在目前的研究中,我们应用了一种计算方法来预测开发的抑制剂的选择性特征。对包含 30 种先前开发的抑制剂的 2-氨基苯甲酰胺数据集进行分子对接,然后进行 MD 模拟和结合自由能计算。对于每种 HDAC 异构体,发现结合自由能值和体外抑制活性之间存在显着相关性。在新设计和合成的抑制剂的外部测试集上评估了最佳预成型模型的预测准确性和可靠性。
