Human 15-lipoxygenase-1 (15-LOX-1) is a mammalian lipoxygenase which plays an important regulatory role in several CNS and inflammatory lung diseases. To further explore the role of this enzyme in drug discovery, novel potent inhibitors with favorable physicochemical properties are required. In order to identify such new inhibitors, we established a combinatorial screening method based on acylhydrazone

from DCC was validated using STD-NMR, and molecular modeling studies revealed the ability of the compounds to bind HuR at the mRNA binding pocket. Notably, three compounds effectively interfered with HuR–RNA binding in fluorescence polarization studies, suggesting their potential as foundational compounds for developing anticancer HuR–RNA interfering agents.

applied for the first-time protein-templated dynamic combinatorial chemistry on RAD51 as a hit identification strategy. Upon design of N-acylhydrazone-based dynamic combinatorial libraries, RAD51 showed a clear templating effect, amplifying 19 N-acylhydrazones. Screening against the RAD51–BRCA2 protein–protein interaction via ELISA assay afforded 10 inhibitors in the micromolar range. Further 19F NMR experiments
RAD51 是一种 ATP 依赖性重组酶,由 BRCA2 募集以通过同源重组介导 DNA 双链断裂修复,是一种有吸引力的抗癌药物靶点。在这里,我们首次在 RAD51 上申请了蛋白质模板化的动态组合化学作为命中识别策略。在设计基于N-酰基腙的动态组合文库后,RAD51 显示出明显的模板效应,可扩增 19 个N-酰基腙。通过 ELISA 测定筛选 RAD51-BRCA2 蛋白质-蛋白质相互作用,提供了 10 种微摩尔范围内的抑制剂。进一步的19 F NMR 实验表明,7可以结合 RAD51 并被 BRC4 取代,表明在 BRCA2 的同一结合口袋中存在相互作用。这些结果不仅证明了 ptDCC 可以成功地应用于全长寡聚 RAD51,而且还可以解决对鉴定小分子 PPI 抑制剂的替代策略的需求。
