synthesis of inhibitors for several enzymes including PARP15 and SIRT6. The high dissimilarity of NADEL screening fingerprints for different proteins translated into inhibitors that showed selectivity for their target. The discovery of patterns of enriched structures for six out of eight tested proteins is remarkable for a library of 58 302 DNA-tagged structures and illustrates the prospect of focused DNA-encoded
DNA 编码的化学文库越来越多地用于药物研究,因为它们能够快速发现合成蛋白质配体。在这里,我们探讨了以目标类别为重点的 DNA 编码化学文库是否可以成为实现一系列蛋白质稳健筛选效率的经济高效的工具。该研究表明,为 NAD+ 结合口袋 (NADEL) 设计的 DNA 编码文库有效地对具有 ADP-核糖基转移酶活性的酶的化学结合空间进行采样。提取的信息指导合成多种酶的抑制剂,包括 PARP15 和 SIRT6。不同蛋白质的 NADEL 筛选指纹的高度相似性转化为抑制剂,对其靶标显示出选择性。

A new series of CCR2 antagonists has been discovered that incorporates intramolecular hydrogen bonding as a strategy for rigidifying the scaffold. The structure-activity relationship was established through initial systematic modification of substitution pattern and chain length, followed by independent optimization of three different substituents (benzylamine, carboxamide, and benzamide). Several of the acyclic compounds display 10-30 nM binding affinity for CCR2. Moreover, these antagonists are able to block both MCP-1-induced Ca2+ flux and monocyte chemotaxis, and are selective for binding to CCR2 over CCR1 and CCR3. (C) 2007 Elsevier Ltd.

investigate this issue, we recorded a series of NMRspectra with A11 purchased from Fluorochem (catalog no. 313748, lot 2; Figures S19–S23 in the updated Supporting Information). The 1H NMR spectrum of A11 was the same as that obtained for the reference compound A108 (enamine, catalog no. EN300-23945; Figure S24 in the Supporting Information). In the HMBC spectra (Figure S23 in the Supporting Information)
