Bcl-2-associated athanogene 3 (BAG3) protein plays multiple roles in controlling cellular homeostasis, and it has been reported to be deregulated in many cancers, leading tumor cell apoptosis escape. BAG3 protein is then an emerging target for its oncogenic activities in both leukemia and solid cancers, such as medulloblastoma. In this work a series of forty-four compounds were designed and successfully synthesized
Bcl-2 相关athanogene 3 (BAG3) 蛋白在控制细胞稳态中发挥多种作用,据报道,它在许多癌症中失调,导致肿瘤细胞凋亡逃逸。BAG3 蛋白是其在白血病和实体癌(如髓母细胞瘤)中致癌活性的新兴靶标。在这项工作中,通过对先前报道的 2,4-噻唑烷二酮衍生物 28 的修饰和优化,设计并成功合成了一系列 44 种化合物。通过在人胚胎肾 HEK-293T 细胞中进行高效克隆和转染,分别通过 IMAC 和 SEC 等色谱技术收集和纯化 BAG3。随后,通过表面等离子体共振 (SPR) 评估了所有化合物与 BAG3 的结合能力,突出化合物 FB49 是对蛋白质具有最大亲和力的化合物 (Kd = 45 ± 6 μM),也对参比化合物 28。通过饱和转移差 (STD) 核磁共振 (NMR) 波谱进行的进一步分析进一步证实了 FB49 对蛋白质的最高亲和力。体外生物学研究表明,化合物 FB49
