蛋白质-蛋白质相互作用对于调节翻译起始因子和许多其他细胞过程的活性至关重要,并且形成了药物开发中最大的未开发但最具挑战性的靶点。4 EGI-1,(E/Z)-2-(2-(4-(3,4-二氯苯基)噻唑-2-基)亚肼基)-3-(2-硝基苯基)丙酸,是在小分子文库的筛选活动中发现的作为翻译起始因子eIF 4 E和eIF 4G蛋白质-蛋白质相互作用抑制剂的热门化合物;它在体外和体内抑制翻译起始。设计并合成了一系列4 EGI-1-衍生的噻唑-2-基腙,以描绘结构纬度并提高其与eIF 4 E的结合亲和力,并增加其抑制eIF 4 E/eIF 4G相互作用的效力。在4 EGI-1的E-和Z-异构体的情况下,探测包含3-苯基丙酸和4-苯基噻唑烷部分的两个苯环上的宽范围的取代基导致具有增强的结合亲和力和翻译起始抑制活性的类似物。
Protein-protein interactions are critical for regulating the activity of translation initiation factors and multitude of other cellular process, and form the largest block of untapped albeit most challenging targets for drug development. 4EGI-1, (E/Z)-2-(2-(4-(3,4-dichlorophenyl)thiazol-2-yl)hydrazono)-3-(2-nitrophenyl)propanoic acid, is a hit compound discovered in a screening campaign of small molecule libraries as an inhibitor of translation initiation factors eIF4E and eIF4G protein-protein interaction; it inhibits translation initiation in vitro and in vivo. A series of 4EGI-1-derived thiazol-2-yl hydrazones have been designed and synthesized in order to delineate the structural latitude and improve its binding affinity to eIF4E, and increase its potency in inhibiting the eIF4E/eIF4G interaction. Probing a wide range of substituents on both phenyl rings comprising the 3-phenylpropionic acid and 4-phenylthiazolidine moieties in the context of both E- and Z-isomers of 4EGI-1 led to analogs with enhanced binding affinity and translation initiation inhibitory activities.
