  纳摩尔 DCAF1 小分子配体的发现

  摘要：

  DCAF1 是两种不同 E3 连接酶（CRL4 DCAF1和 EDVP）的底物受体，在蛋白质降解中发挥着关键的生理作用，被认为是多种癌症的药物靶点。 DCAF1 拮抗剂可用于开发癌症和病毒治疗疗法。我们使用 DCAF1 的 WDR 结构域筛选包含 1140 亿个化合物的 DNA 编码库 (DEL)，并使用相似性搜索和机器学习识别候选化合物。由此发现了一种 SPR KD为11 μM 的化合物 (Z1391232269)。结构引导的命中优化导致 OICR-8268 ( 26e ) 的发现，通过细胞热位移测定 (CETSA) 测量，其 SPR K D为 38 nM，细胞靶标结合 EC 50为 10 μM。 OICR-8268 是一种出色的工具化合物，可用于开发用于癌症治疗的下一代 DCAF1 配体、进一步研究 DCAF1 在细胞中的功能以及开发基于 DCAF1 的 PROTAC。

  Asymmetric synthesis of β-fluoroaryl-β-amino acids

  摘要：

  The conjugate addition of lithium (R)-N-benzyl-N-(alpha-methylbenzyl)amide to a range of beta-fluoroaryl-alpha,beta-unsaturated esters gave the corresponding beta-amino esters with high diastereoselectivity and in good isolated yields. Sequential treatment of the resultant beta-fluoroaryl-beta-amino esters under optimised hydrogenolysis conditions, followed by ester hydrolysis with 2.0 M aq HCl, provided access to a range of beta-fluoroaryl-beta-amino acids in good yield.

  isomerization of various racemic α- and β-arylalanines catalysed by phenylalanine 2,3-aminomutase from Pantoea agglomerans (PaPAM) was investigated. Both α- and β-arylalanines were accepted as substrates when the aryl moiety was relatively small, like phenyl, 2-, 3-, 4-fluorophenyl or thiophen-2-yl. While 2-substituted α-phenylalanines bearing bulky electron withdrawing substituents did not react, the corresponding

In spite of this, a method combining the higher conversion of EncP with a strict α‐lyase from Anabaena variabilis (AvPAL) was found to be more amenable, allowing kinetic resolution of five racemic substrates and a preparative‐scale reaction with >98% (R)

  An efficient synthesis of β-aryl-β-amino acid enantiomers has been developed via the lipase-catalysed enantioselective hydrolysis of the corresponding racemic ethyl esters in an organic solvent. High enantioselectivities (E >100) were observed when the lipase PS-catalysed reactions were performed with H2O (0.5 equiv) in diisopropyl ether at 45 °C. The products could be easily separated and were obtained
