  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。

• Direct Catalytic Enantioselective Benzylation from Aryl Acetic Acids

  We demonstrate that metal-catalyzed enantioselective benzylation reactions of allylic electrophiles can occur directly from aryl acetic acids. The reaction proceeds via a pathway in which decarboxylation is the terminal event, occurring after stereoselective carbon-carbon bond formation. This mechanistic feature enables enantioselective benzylation without the generation of a highly basic nucleophile

  我们证明了金属催化的烯丙基亲电试剂的对映选择性苄基化反应可以直接从芳基乙酸中发生。该反应通过其中脱羧是最终事件的途径进行，发生在立体选择性碳-碳键形成之后。这种机制特征可以实现对映选择性苄基化，而不会产生强碱性亲核试剂。因此，该过程具有广泛的官能团兼容性，这在采用已建立的协议时是不可能的。
