Discovery of 14-3-3 Protein-Protein Interaction Inhibitors that Sensitize Multidrug-Resistant Cancer Cells to Doxorubicin and the Akt Inhibitor GSK690693
synthesis, image‐based high‐content analysis of reporter cells, and in vitro assays using cancercells. Notably, the two most active compounds promoted the translocation of c‐Abl and FOXO pro‐apoptotic factors into the nucleus and sensitized multidrug‐resistant cancercells to apoptotic inducers such as doxorubicin and the pan‐AktinhibitorGSK690693, thus becoming valuable lead candidates for further optimization

BV02 is a reference inhibitor of 14-3-3 protein-protein interactions, which is currently used as chemical biology tool to understand the role of 14-3-3 proteins in pathological contexts. Due to chemical instability in certain conditions, its bioactive form has remained unclear. Here, we use NMR spectroscopy to prove for the first time the direct interaction between the molecule and 14-3-3 sigma, and to depict its bioactive form, namely the phthalimide derivative 9. Our work provides molecular insights to the bioactive form of the 14-3-3 PPI inhibitor and facilitates further development as candidate therapeutic agent. (C) 2015 Elsevier Ltd. All rights reserved.

Chemically stable inhibitors of 14-3-3 protein–protein interactions derived from BV02
Abstract 14-3-3 are regulatory proteins that through protein–proteininteractions (PPI) with numerous binding partners could be involved in several human diseases, including cancer, neurodegenerative disorders, and pathogens infections. Following our research interest in the development of 14-3-3 PPI inhibitors, here we exploited the privileged 4-aminoantipyrine scaffold in the design and synthesis
摘要 14-3-3 是调节蛋白,通过与众多结合伙伴的蛋白-蛋白相互作用 (PPI),可参与多种人类疾病,包括癌症、神经退行性疾病和病原体感染。根据我们对开发 14-3-3 PPI 抑制剂的研究兴趣,我们在此利用特权 4-氨基安替比林支架设计和合成一些具有抗 K-562 细胞增殖活性的衍生物,并能够与重组 14 -3-3σ 由 NMR 光谱证明。通过分子建模进一步探索了结合模式,而将共聚焦显微镜与强度分析相结合表明化合物1能够在低微摩尔浓度下促进 c-Abl 的核转位。总的来说,1与母体 14-3-3 PPI 抑制剂相比,其化学性质稳定,因此成为进一步开发的确认热门产品。
