  Development of Mithramycin Analogues with Increased Selectivity toward ETS Transcription Factor Expressing Cancers

  摘要：

  Mithramycin A (1) was identified as the top potential inhibitor of the aberrant ETS transcription factor EWSFLI1, which causes Ewing sarcoma. Unfortunately, 1 has a narrow therapeutic window, compelling us to seek less toxic and more selective analogues. Here, we used MTMSA (2) to generate analogues via peptide coupling and fragment-based drug development strategies. Cytotoxicity assays in ETS and non-ETS dependent cell lines identified two dipeptide analogues, 60 and 61, with 19.1- and 15.6-fold selectivity, respectively, compared to 1.5-fold for 1. Importantly, the cytotoxicity of 60 and 61 is <100 nM in ETS cells. Molecular assays demonstrated the inhibitory capacity of these analogues against EWS-FLI1 mediated transcription in Ewing sarcoma. Structural analysis shows that positioning the tryptophan residue in a distal position improves selectivity, presumably via interaction with the ETS transcription factor. Thus, these analogues may present new ways to target transcription factors for clinical use.

  发现可激活鸟嘌呤核苷酸交换因子 SOS1 并调节 RAS 信号转导的氨基哌啶吲哚

  摘要：

  RAS 活性失调通常是突变的结果，约 30% 的人类癌症与此有关。尽管有这一统计数据，但尚未开发出针对 RAS 驱动肿瘤的临床成功治疗方法。调节 RAS 活性的一种方法是靶向并影响与 RAS 相互作用的蛋白质的活性，例如七同源物 1 (SOS1) 的鸟嘌呤核苷酸交换因子 (GEF)。在这里，我们报告了吲哚系列化合物的构效关系 (SAR)。使用基于结构的设计，我们系统地探索了吲哚核、悬垂氨基酸部分以及连接这两个片段的连接单元的取代模式。一流的化合物可在体外以亚微摩尔浓度激活核苷酸交换过程，提高 HeLa 细胞中活性 RAS-GTP 的水平，并引发丝裂原激活蛋白激酶 - 细胞外调节激酶 (MAPK-ERK) 通路中的信号传导变化，导致较高化合物浓度下pERK1/2 T202/Y204蛋白水平降低。

  Deregulated RAS activity, often the result of mutation, is implicated in approximately 30% of all human cancers. Despite this statistic, no clinically successful treatment for RAS-driven tumors has yet been developed. One approach for modulating RAS activity is to target and affect the activity of proteins that interact with RAS, such as the guanine nucleotide exchange factor (GEF) son of sevenless

• Palladium-Catalyzed, Modular Synthesis of Highly Functionalized Indoles and Tryptophans by Direct Annulation of Substituted <i>o</i>-Haloanilines and Aldehydes

  One-pot synthesis of indoles by a palladium-catalyzed annulation of ortho-haloanilines and aldehydes has been developed. Coupling of ortho-iodoaniline with aldehyde is realized under mild ligandless conditions [Pd(OAc)2, DABCO, DMF, 85 °C], whereas X-Phos is found to be the ligand of choice for coupling reactions involving ortho-chloroanilines/ortho-bromoanilines and aldehydes. A variety of ortho-haloanilines
