available inhibitors of the ATP binding site of this protein, we conducted fragment screening and virtual screening in parallel against Hsp90. This approach quickly identified 2-aminotriazine and 2-aminopyrimidine derivatives as specific ligands to Hsp90 with high ligand efficiency. In silico evaluation of the 3D X-ray Hsp90 complex structures of the identified hits allowed us to promptly design CH5015765
热激蛋白90(Hsp90)是一种分子伴侣蛋白,可调节其底物蛋白(称为客户蛋白)的成熟和稳定。Hsp90的许多客户蛋白都参与了肿瘤的进展和存活,因此Hsp90可以成为开发抗癌药物的良好靶标。为了有效鉴定该蛋白质的ATP结合位点的新型口服可用抑制剂,我们并行针对Hsp90进行了片段筛选和虚拟筛选。这种方法很快鉴定出2-氨基三嗪和2-氨基嘧啶衍生物是Hsp90的特异性配体,具有很高的配体效率。在对命中的3D X射线Hsp90复杂结构进行计算机分析后,我们得以迅速设计CH5015765,
