Compounds of formula (I) and salts thereof: wherein R1, R2, R3, R4 are defined herein. Compounds of formula (I) and salts thereof have been found to inhibit the binding of the BET family of bromodomain proteins to, for example, acetylated lysine residues and thus may have use in therapy, for example in the treatment of autoimmune and inflammatory diseases, such as rheumatoid arthritis; and cancers.

obstacle in developing selective CBX ChD inhibitors. Here we report the selection of small, focused, DNA-encodedlibraries (DELs) against multiple homologous ChDs to identify modifications to a parental ligand that confer both selectivity and potency for the ChD of CBX8. This on-DNA, medicinal chemistry approach enabled the development of SW2_110A, a selective, cell-permeable inhibitor of the CBX8 ChD. SW2_110A
structures. Herein, we report a generally applicable method for synthesis of natural-product-like cyclophane-braced peptide macrocycles via Pd-catalyzed intramolecular C(sp3)-H arylation with aryl iodides at the remote γ position of various N-terminal aliphatic aminoacid units using a simple picolinamide directing group. Products of high structural and stereochemical complexity were quickly assembled
环肽为探索小分子和生物制剂之间的生物相关化学空间提供了最重要的平台之一。然而,与小分子的设计和合成相比,化学家对环肽三维结构和性质的微调能力远远落后。对环烷肽天然产物很感兴趣,我们想知道刚性、平面和疏水性环烷基序是否可以为合成具有良好 3D 结构的环肽提供新的设计元素。在此处,我们报告了一种普遍适用的合成天然产物样环芳支撑的肽大环化合物的方法,通过 Pd 催化的分子内 C(sp3)-H 芳基化,在各种 N 端脂肪族氨基酸单元的远程 γ 位置使用芳基碘进行芳基化,使用简单的吡啶酰胺导向基团。通过标准固相肽合成制备的易于获得的肽前体快速组装具有高度结构和立体化学复杂性的产品。许多这些肽大环化合物显示出高度有序的结构,正如 X 射线晶体学所揭示的那样。值得注意的是,带有各种游离极性侧链的未受保护肽底物的 PA 导向 C(sp3)-H 环化反应在水性介质中以高效率和选择性进行。

induces a skeletalrearrangement in viridicatin biosynthesis in Aspergillus nidulans, generating a quinolone scaffold from benzo[1,4]diazepine‐2,5‐dione substrates. We report that AsqJ catalyzes an additional, entirely different reaction, simply by a change in substituent in the benzodiazepinedione substrate. This new mechanism is established by substrate screening, application of functional probes, and
先前的研究表明,Fe II /α-酮戊二酸依赖性双加氧酶AsqJ诱导构巢曲霉在viridicatin生物合成中的骨架重排,从苯并[1,4]二氮杂-2,5-二酮底物生成喹诺酮骨架。我们报告说,仅通过改变苯并二氮杂二酮底物中的取代基,AsqJ即可催化另外的,完全不同的反应。通过底物筛选,功能探针的应用和计算分析来建立这种新机制。AsqJ消费税H 2由合适的苯并[1,4]二氮杂-2-5,5-二酮底物的杂环结构生成CO,生成喹唑啉酮。这种新颖的AsqJ催化途径由复杂底物中的单个取代基控制。AsqJ的这种独特的底物定向反应性可实现喹诺酮或喹唑啉酮的靶向生物催化生成,喹诺酮或喹唑啉酮是两种具有特殊生物医学相关性的生物碱框架。
