  Secondary Amides of Sulfonylated 3-Amidinophenylalanine. New Potent and Selective Inhibitors of Matriptase

  摘要：

  Matriptase is an epithelium-derived type II transmembrane serine protease and has been implicated in the activation of substrates such as pro-HGF/SF and pro-uPA, which are likely involved in tumor progression and metastasis. Through screening, we have identified bis-basic secondary amides of sulfonylated 3-amidinophenylalanine as matriptase inhibitors. X-ray analyses of analogues 8 and 31 in complex with matriptase revealed that these inhibitors occupy, in addition to part of the previously described S4-binding site, the cleft formed by the molecular surface and the unique 60 loop of matriptase. Therefore, optimization of the inhibitors included the incorporation of appropriate sulfonyl substituents that could improve binding of these inhibitors into both characteristic matriptase subsites. The most potent derivatives inhibit matriptase highly selective with K(i) values below 5 nM. Molecular modeling revealed that their improved affinity results from interaction with the S4 site of matriptase. Analogues 8 and 59 were studied in an orthotopic xenograft mouse model of prostate cancer. Compared to control, both inhibitors reduced tumor growth, as well as tumor dissemination.

  A platform to accelerate optimization of proteolysis targeting chimeras (PROTACs) has been developed using a direct-to-biology (D2B) approach with a focus on linker effects. A large number of linker analogs─with varying length, polarity, and rigidity─were rapidly prepared and characterized in four cell-based assays by streamlining time-consuming steps in synthesis and purification. The expansive dataset

  使用直接生物学（D2B）方法开发了一个加速优化蛋白水解靶向嵌合体（PROTAC）的平台，重点关注链接效应。通过简化耗时的合成和纯化步骤，在四种基于细胞的测定中快速制备并表征了大量具有不同长度、极性和刚性的接头类似物。广泛的数据集提供了有关细胞内 E3 连接酶靶标参与、降解、渗透性和细胞毒性的接头结构-活性关系 (SAR) 的信息。发现了链接器 SAR 的意外方面，与“链接器学”的文献报道一致，并且该方法极大地加速了经验优化。物理化学性质趋势出现，该平台有潜力快速扩展更复杂预测模型的训练集。我们进行了深入的验证研究，并确认 D2B 平台是加速 PROTAC 设计-制造-测试周期的宝贵工具。

  A series of indazoles have been discovered as KHK inhibitors from a pyrazole hit identified through fragment-based drug discovery (FBDD). The optimization process guided by both X-ray crystallography and solution activity resulted in lead-like compounds with good pharmaceutical properties. (C) 2011 Elsevier Ltd. All rights reserved.
