  acids, which selectively inhibit LMP7 while sparing all other subunits. The exploitation of structural differences between the proteasome subunits culminated in the identification of the highly potent, exquisitely selective, and orally available LMP7 inhibitor 50 (M3258). Based on the strong antitumor activity observed with M3258 in MM models and a favorable preclinical data package, a phase I clinical

  蛋白酶体是泛素依赖性蛋白质降解途径中广泛表达的关键成分，其中包含具有催化活性的亚基（β1、β2 和 β5）。LMP7 (β5i) 是免疫蛋白酶体的一个亚基，是一种主要在造血细胞中表达的诱导型异构体。用于治疗多发性骨髓瘤 (MM) 的临床有效的泛蛋白酶体抑制剂非选择性靶向 LMP7 和组成型蛋白酶体和免疫蛋白酶体的其他亚基，具有相当的效力，这可能会限制这些药物的治疗适用性。在这里，我们描述了新型酰氨基硼酸的发现和基于结构的命中优化，它选择性地抑制 LMP7，同时保留所有其他亚基。对蛋白酶体亚基之间结构差异的开发最终确定了高效能，50 (M3258)。基于 M3258 在 MM 模型中观察到的强大抗肿瘤活性和有利的临床前数据包，在复发/难治性 MM 患者中启动了 I 期临床试验。

  In this report, we describe a new photoredox catalyzed 1,4-conjugate addition of N-substituted acetic acids to electron-deficient olefins via decarboxylative C-C bond formation. This C-C bond formation occurred under mild conditions enabled by visible light irradiation. This transformation facilitated the synthesis of biologically relevant N-substituted heterocyclic structural motifs not readily accessible

  在本报告中，我们描述了一种新的光氧化还原催化 1,4-共轭加成 N-取代的乙酸通过脱羧 CC 键形成缺电子烯烃。这种CC键形成发生在可见光照射的温和条件下。这种转化促进了其他方法不易获得的生物学相关的 N 取代杂环结构基序的合成。CC键形成方案应用于弱亲核杂环，如吲哚、吲唑、咪唑和环状酰胺，以形成功能化的药物样小分子。

  3-indandione scaffold is an important structural motif used in the preparation of a large number of industrial chemical and pharmaceutical compounds. However, few approaches allow for the direct C2 acylation on these building blocks. A method was developed using DMAP and EDCI, which is mild in reactivity, covers a diverse range of carboxylic acid acylating agents, is compatible with electron releasing
