  鉴定具有改善的活性的BTK和JAK3高效抑制剂，用于治疗B细胞淋巴瘤。

  摘要：

  BTK和JAK3受体酪氨酸激酶是治疗B细胞淋巴瘤的两个有效靶点。在这里，我们报告鉴定几类嘧啶衍生物作为有效的BTK和JAK3双重抑制剂。在这些分子中，大约三分之二的化合物在浓度低于10 nM时显示出强大的抑制能力，还有四种化合物（7e，7g，7m和7n浓度低于1 nM时，可显着抑制BTK和JAK3酶的磷酸化。另外，与代表性的BTK抑制剂依鲁替尼相比，这些嘧啶衍生物还表现出增强的活性以阻断B细胞淋巴瘤细胞的增殖。特别地，在基于细胞的评估中，两种结构特异性化合物7b和7e表现出比参比剂更强的活性，且IC 50值低于10μM。进一步的生物学研究，包括流式细胞术分析和体内异种移植模型评估也表明了它们在治疗B细胞淋巴瘤方面的功效和低毒性。这些发现为开发具有多靶点作用的新型抗B细胞淋巴瘤药物提供了新的见识。

  Potent human glutaminyl cyclase inhibitors as potential anti-Alzheimer’s agents: Structure-activity relationship study of Arg-mimetic region

  摘要：

  Pyroglutamate-modified amyloid beta peptides (pGlu-A beta) are highly neurotoxic and promote the formation of amyloid plaques. The pGlu-A beta peptides are generated by glutaminyl cyclase (QC), and recent clinical studies indicate that QC represents an alternative therapeutic target to treat Alzheimer's disease (AD). We have previously developed a series of QC inhibitors with an extended pharmacophoric scaffold, termed the Arg-mimetic D-region. In the present study, we focused on the structure activity relationship (SAR) of analogues with modifications in the D-region and evaluated their biological activity. Most compounds in this series exhibited potent activity in vitro, and our SAR analysis and the molecular docking studies identified compound 202 as a potential candidate because it forms an additional hydrophobic interaction in the hQC active site. Overall, our study provides valuable insights into the Arg-mimetic pharmacophore that will guide the design of novel QC inhibitors as potential treatments for AD. (C) 2018 Elsevier Ltd.

  therapeutically amenable targets in the treatment of B-cell lymphomas. Here we report the identification of several classes of pyrimidine derivatives as potent BTK and JAK3 dual inhibitors. Among these molecules, approximately two thirds displayed strong inhibitory capacity at less than 10 nM concentration, and four compounds (7e, 7g, 7m and 7n) could significantly inhibit the phosphorylation of BTK and JAK3
