inhibitors of this protein are useful in the treatment of cardiomyopathy and neurodegenerative diseases. For the discovery of novel Caspase-3 non-peptide inhibitors from Maybridge database, ligand based and structure based virtual screening methods were used. Quantitative 3D pharmacophore models were generated using 25 known inhibitors of Caspase-3 and it was used as initial screen to retrieve the hits
属于半胱氨酸蛋白酶家族的Caspase-3是凋亡级联途径的主要执行者。该蛋白的抑制剂可用于治疗心肌病和神经退行性疾病。为了从Maybridge数据库中发现新型Caspase-3非肽抑制剂,使用了基于配体和基于结构的虚拟筛选方法。使用25种已知的Caspase-3抑制剂生成了定量3D药效团模型,并将其用作初始筛选以从数据库中检索匹配数据。对这些具有高估计活性的化合物进行了类药物性质的分析,并进行了对接研究,以研究新命中点与活性位点之间的相互作用。选择具有良好预测的命中之一(AW01208)进行合成和生物学筛选。
