A series of benzylidene-1H-indol-2-one (oxindole) derivatives was synthesized and evaluated as cRaf-1 kinase inhibitors. The key features of the molecules were the donor/acceptor motif common to kinase inhibitors and a critical acidic phenol flanked by two substitutions. Diverse 5-position substitutions provided compounds with low nanomolar kinase enzyme inhibition and inhibited the intracellular MAPK pathway. (C) 2000 Elsevier Science Ltd. All rights reserved.

Microtubule-dependent molecular motors that function during mitosis are logical alternative mitotic targets for drug development. Eg5 (Kinesin-5) and Kif15 (Kinesin-12), in particular, are an attractive pair of motorproteins, as they work in concert to drive centrosome separation and promote spindle bipolarity. Furthermore, we hypothesize that the clinical failure of Eg5 inhibitors may be (in part) due

been considered a promiscuous kinase inhibitor template, but across these four specific literature oxindoles TLK2 activity was consistent, while the kinome profile was radically different ranging from narrow to broadspectrum kinome coverage. We synthesized a large series of analogues, utilizing quantitative structure-activity relationship (QSAR) analysis, water mapping of the kinase ATP binding sites
羟吲哚支架一直是多个激酶药物发现项目的中心,其中一些项目已导致药物获得批准。从文献中鉴定出一系列两个羟吲哚匹配对,其中 TLK2 作为脱靶激酶被有效抑制。长期以来,羟吲哚一直被认为是一种混杂的激酶抑制剂模板,但在这四个特定文献中,羟吲哚 TLK2 活性是一致的,而激酶组谱却截然不同,从窄谱到广谱激酶组覆盖范围。我们合成了大量的类似物,利用定量构效关系 (QSAR) 分析、激酶 ATP 结合位点的水图谱、激酶组分析和小分子 X 射线结构分析来优化 TLK2 抑制和激酶组选择性。这导致了几种窄谱、亚家族选择性化学工具化合物的鉴定,包括 (UNC-CA2-103),它们可以阐明 TLK2 生物学。
