  发现一系列新型咪唑并吡嗪衍生物作为有效的 SHP2 变构抑制剂

  摘要：

  蛋白酪氨酸磷酸酶SHP2是一种致癌蛋白，可以调节不同的细胞因子受体和受体酪氨酸激酶信号通路。我们在此报告了一系列新型 SHP2 变构抑制剂的鉴定，该抑制剂具有咪唑并吡嗪 6,5 稠合杂环系统作为中心支架，在酶和细胞测定中显示出良好的效力。 SAR 研究导致了化合物8的鉴定，它是一种高效的 SHP2 变构抑制剂。 X 射线研究表明，与已知的 SHP2 抑制剂相比，具有新颖的稳定相互作用。随后的优化使我们能够鉴定出类似物10 ，它在啮齿动物中具有出色的效力和有前景的 PK 特性。

  Optimization of 5-substituted thiazolyl ureas and 6-substituted imidazopyridines as potential HIV-1 latency reversing agents

  摘要：

  A persistent latent reservoir of virus in CD4(+) T cells is a major barrier to cure HIV. Activating viral transcription in latently infected cells using small molecules is one strategy being explored to eliminate latency. We previously described the use of a FlpIn.FM HEK293 cellular assay to identify and then optimize the 2-acylaminothiazole class to exhibit modest activation of HIV gene expression. Here, we implement two strategies to further improve the activation of viral gene expression and physicochemical properties of this class. Firstly, we explored rigidification of the central oxy-carbon linker with a variety of saturated heterocycles, and secondly, investigated bioisosteric replacement of the 2-acylaminothiazole moiety. The optimization process afforded lead compounds (74 and 91) from the 2-piperazinyl thiazolyl urea and the imidazopyridine class. The lead compounds from each class demonstrate potent activation of HIV gene expression in the FlpIn.FM HEK293 cellular assay (both with LTR EC(50)s of 80 nM) and in the Jurkat Latency 10.6 cell model (LTR EC50 220 and 320 nM respectively), but consequently activate gene expression non-specifically in the FlpIn.FM HEK293 cellular assay (CMV EC50 70 and 270 nM respectively) manifesting in cellular cytotoxicity. The lead compounds have potential for further development as novel latency reversing agents. (C) 2020 Elsevier Masson SAS. All rights reserved.
