reaction process was developed for the convenient and cheap synthesis of spirooxindole derivatives. One-pot reactions of isatins, malononitrile (or ethyl cyanoacetate), hydrazine hydrate (or phenylhydrazine), and 1,3-dicarbonyl compounds were compared with one-pot reactions of isatins, malononitrile (or ethyl cyanoacetate), and 5-pyrazolone derivatives. Both sets of reaction were conducted in EtOH in the
开发了一种有效且清洁的反应过程,以方便且廉价地合成螺并吲哚衍生物。比较了靛红,丙二腈(或氰基乙酸乙酯),水合肼(或苯肼)和1,3-二羰基化合物的一锅法反应与靛红,丙二腈(或氰基乙酸乙酯)和5-吡唑啉酮衍生物的一锅法反应。 。两组反应均在4-DMAP催化剂存在下于EtOH中进行。使用四组分一锅法快速快速获得了一系列螺[吲哚啉-3,4'-吡喃并[2,3- c ]吡唑]衍生物。

ubiquitin precursors. Despite growing interest in DUB biological function and potential as therapeutic targets, few selective small-molecule inhibitors and no approved drugs currently exist. To identify chemical scaffolds targeting specific DUBs and establish a broader framework for future inhibitor development across the gene family, we performed high-throughput screening of a chemically diverse small-molecule
