    Synthesis and biological evaluation of naphthoquinone analogs as a novel class of proteasome inhibitors
    摘要:
    Screening of the NCI Diversity Set-1 identified PI-083 (NSC-45382) a proteasome inhibitor selective for cancer over normal cells. Focused libraries of novel compounds based on PI-083 chloronaphthoquinone and sulfonamide moieties were synthesized to gain a better understanding of the structure-activity relationship responsible for chymotrypsin-like proteasome inhibitory activity. This led to the demonstration that the chloronaphthoquinone and the sulfonamide moieties are critical for inhibitory activity. The pyridyl group in PI-083 can be replaced with other heterocyclic groups without significant loss of activity. Molecular modeling studies were also performed to explore the detailed interactions of PI-083 and its derivatives with the beta 5 and beta 6 subunits of the 20S proteasome. The refined model showed an H-bond interaction between the Asp-114 and the sulfonamide moiety of the PI-083 in the beta 6 subunit. (C) 2010 Elsevier Ltd. All rights reserved.

    critical role in human physiology, and its dysregulation can lead to an array of diseases. β-Catenin is a multifunctional protein within this pathway and an attractive yet challenging therapeutic target, most notably in oncology. This has stimulated the search for potent small-molecule inhibitors binding directly to the β-catenin surface to inhibit its protein–protein interactions and downstream signaling
    典型的 Wingless 相关整合位点信号通路在人体生理学中发挥着关键作用,其失调可导致一系列疾病。β-连环蛋白是该途径中的一种多功能蛋白,是一种有吸引力但具有挑战性的治疗靶点,尤其是在肿瘤学中。这刺激了对直接与β-连环蛋白表面结合以抑制其蛋白质-蛋白质相互作用和下游信号传导的有效小分子抑制剂的研究。在这里,我们提供了文献中声称的(和一些推定的)β-连环蛋白小分子配体的说明。通过计算机分析,我们表明大多数这些分子含有混杂的化学亚结构,这些亚结构因干扰筛选试验而臭名昭著。最后,根据这个分析,我们使用正交生物物理技术证明,所检查的小分子都没有结合在 β- 连环蛋白的表面。在对他们报道的作用方式提出质疑的同时,这项研究还重申了 β-连环蛋白是药物发现的一个重要目标。
