  一般访问以C为中心的基团：在水介质中结合生物启发性光催化剂与硼酸

  摘要：

  以碳为中心的自由基是现代合成化学必不可少的组成部分。近年来，可见光光氧化还原催化已成为从包括硼酸在内的广泛的潜在官能团中进入以C为中心的自由基的有前途的途径。在本文中，我们介绍了一种水性方案，其中水起着星形作用，以帮助将脂族，芳族和杂芳族硼酸转化为C具有生物启发性的黄素光催化剂的中心自由基。这些自由基通过开壳共轭物加成到不同的Michael受体上，以递送各种不同的烷基化产物，包括三种药学上相关的化合物。通过计算研究，氘标记，自由基捕获实验和光谱分析研究了反应机理。

  even test up to 96 single-NPAA peptide variants via the unique combination of boronic acids and a dehydroalanine residue in a peptide. We showcase the power of our newly minted platform to introduce NPAAs of diverse chemotypes-aliphatic, aromatic, heteroaromatic-directly into peptides, including 15 entirely new residues, and to evolve a simple proteinogenic peptide into an unnatural inhibitor of thrombin

  大多数肽药物都含有非蛋白氨基酸 (NPAA)，这些氨基酸是通过使用固相肽合成 (SPPS) 进行的广泛构效关系 (SAR) 研究而产生的。 NPAA 的合成费力且制造成本昂贵，耦合效率也较差，只能通过传统 SPPS 采样一小部分。为了普遍获得含 NPAA 的肽，我们开发了第一代平台，将当代黄素光催化与平行合成相结合，通过硼酸的独特组合，同时制造、纯化、定量，甚至测试多达 96 种单 NPAA 肽变体。肽中的酸和脱氢丙氨酸残基。我们展示了我们新创建的平台的强大功能，可将不同化学类型（脂肪族、芳香族、杂芳香族）的 NPAA 直接引入肽中，包括 15 个全新残基，并通过非经典肽将简单的蛋白肽进化为非天然凝血酶抑制剂特别行政区。

  A series of phenylbipyridinylpyrazoles was synthesized through the reaction of 2-(4-(2-chloropyridin-4-yl)-3-(3-methoxy-5-methylphenyl)-1H-pyrazol-1-yl)acetonitrile (4) with different 6-substituted pyridine-3-ylboronic acids. The final compounds 5a–j were screened at 10 µM against over 60 tumor cell lines at the U.S. National Cancer Institute (NCI). In light of the NCI results, compounds 5c and 5h showed a broad spectrum of activity against NCI cell lines with mean growth of 53% and 58%, respectively. Compound 5e behaved differently as it showed high degree of selectivity and potency by inhibiting 96% of growth of leukemia SR cell line at 10 µM. Standard COMPARE analyses were performed at the GI50 level and the results exhibit high correlation in the form of pairwise correlation coefficient (PCC) of more than 0.6 between three of the current compounds and three standard known anticancer agents. Compound 5e demonstrated high correlation levels with merbarone (NSC S336628) with a PCC value of 0.631. Compound 5h showed a considerably high PCC value of 0.626 with dichloroallyl lawsone, while compound 5i, showed PCC values of 0.601 and 0.604 with both dichloroallyl lawsone and N,N-dibenzyldaunomycin (NSC S268242), respectively. These three standard agents have anticancer activity via two major mechanism of actions, inhibition of topoisomerase II and inhibition of biosynthesis of pyrimidine nucleotides, therefore, compounds 5a–j are promising therapeutic agents for targeting different human malignancies. Prediction of drug-likeness and toxicity of these newly synthesized derivatives were also considered.

  development of a Ni-catalyzed Suzuki–Miyaura cross-coupling that utilizes a weak amine base and performs optimally with water as a cosolvent is reported. The aqueous amine base facilitates an equilibrium between the Ni oxidative addition complex and Ni μ-hydroxo dimers, enabling productive catalysis at low metal loadings (typically 1 mol %). A practical catalytic system is enabled by use of a commercially

  据报道，开发了一种镍催化的 Suzuki-Miyaura 交叉偶联剂，该偶联剂利用弱胺碱并以水作为助溶剂实现最佳性能。含水胺碱促进 Ni 氧化加成络合物和 Ni μ-羟基二聚体之间的平衡，从而在低金属负载量（通常为 1 mol%）下实现高效催化。通过使用市售的 Ni 氧化加成络合物作为预催化剂，可以实现实用的催化体系。温和的条件允许高官能团耐受性和对复杂药物底物的应用，其中一种在 50 g 规模上以 0.5 mol% 的催化剂负载量进行了证明。
