  BRD4 Structure–Activity Relationships of Dual PLK1 Kinase/BRD4 Bromodomain Inhibitor BI-2536

  摘要：

  A focused library of analogues of the dual PLK1 kinase/BRD4 bromodomain inhibitor BI-2536 was prepared and then analyzed for BRD4 and PLK1 inhibitory activities. Particularly, replacement of the cyclopentyl group with a 3-bromobenzyl moiety afforded the most potent BRD4 inhibitor of the series (39j) with a K-i = 8.7 nM, which was equipotent against PLK1. The superior affinity of 39j over the parental compound to BRD4 possibly derives from improved interactions with the WPF shelf. Meanwhile, substitution of the pyrimidine NH with an oxygen atom reversed the PLK1/BRD4 selectivity to convert BI-2536 into a BRD4-selective inhibitor, likely owing to the loss of a critical hydrogen bond in PLK1. We believe further fine-tuning will furnish a BRD4 "magic bullet" or an even more potent PLK1/BRD4 dual inhibitor toward the expansion and improved efficacy of the chemotherapy arsenal.

  The present invention provides compounds of Formula (I), and pharmaceutically compositions thereof. Compounds of Formula (I) are binders of bromodomains and/or bromodomain-containing proteins (e.g., bromo and extra terminal (BET) proteins). Also provided are methods, uses, and kits using the compounds and pharmaceutical compositions for inhibiting the activity (e.g., increased activity) of bromodomains and/or bromodomain- containing proteins and for treating and/or preventing in a subject diseases associated with bromodomains or bromodomain-containing proteins (e.g., proliferative diseases, cardiovascular diseases, viral infections, fibrotic diseases, metabolic diseases, endocrine diseases, and radiation poisoning). The compounds, pharmaceutical compositions, and kits are also useful for male contraception.

  classes suspected to target multiple cellular factors. In this study we used a bioluminescent resonant energy transfer assay to assess bromodomain engagement by a compound series containing bromodomain‐ and kinase‐biasing polypharmacophores based on the known dual BRD4 bromodomain/PLK1 kinase inhibitor BI2536. With this assay, we discovered several novel agents with bromodomain‐selective specificity

  评估小分子配体与细胞中蛋白质靶标的结合为化学探针优化和药物开发提供了有用的信息。虽然存在可以以低通量方式执行的几种技术，但对大型化合物库的系统评估仍然是一个挑战。在评估怀疑针对多个细胞因子的化合物类别时，细胞内参与测量特别有用。在这项研究中，我们使用生物发光共振能量转移测定来评估基于已知双 BRD4 溴结构域/PLK1 激酶抑制剂 BI2536 的包含溴结构域和激酶偏向多药团的化合物系列的溴结构域参与。通过该测定，我们发现了几种具有溴结构域选择性特异性特征和细胞活性的新型药物。因此，
