进行基于配体和基于对接的虚拟筛选以鉴定新的MDM 2抑制剂。具有四个特征的药效团模型用于虚拟筛选,然后进行分子对接。选择17种化合物用于体外MDM 2抑制测定,并且化合物AO-476/43250177、AG-690/37072075、AK-968/15254441、AO-022/43452814和AF-399/25108021显示出有希望的MDM 2抑制活性,Ki值为9.5、8.5、23.4、3.2、3.3、3.4、3.5、和23.1 μM。4种化合物也显示出抗增殖活性,化合物AO-022/43452814是最有效的,对MCF 7(p53 +/+)、MCF 7(p53-/-)、HCT 116(p53 +/+)和HCT 116(p53-/-)细胞系的IC 50值分别为19.35、26.73、12.63和24.14 μM。化合物AO-022/43452814可用作开发靶向MDM 2的抗癌剂的支架。
A ligand-based and docking-based virtual screening was carried out to identify novel MDM2 inhibitors. A pharmacophore model with four features was used for virtual screening, followed by molecular docking. Seventeen compounds were selected for an in vitro MDM2 inhibition assay, and compounds AO-476/43250177, AG-690/37072075, AK-968/15254441, AO-022/43452814, and AF-399/25108021 showed promising MDM2 inhibition activities with Ki values of 9.5, 8.5, 23.4, 3.2, and 23.1 μM, respectively. Four compounds also showed antiproliferative activity, and compound AO-022/43452814 was the most potent hit with IC50 values of 19.35, 26.73, 12.63, and 24.14 μM against MCF7 (p53 +/+), MCF7 (p53 -/-), HCT116 (p53 +/+), and HCT116 (p53 -/-) cell lines, respectively. Compound AO-022/43452814 could be used as a scaffold for the development of anticancer agents targeting MDM2.
