knockdown assay demonstrated that the anti-GBM effect of 5 mainly depended on the expression of PKM2 in vitro and in vivo. Compound 16, a prodrug of 5, markedly suppressed U118 tumor xenograft growth and reduced the weight of tumor. On the basis of these investigations, we propose that 16 might be considered as a promising lead compound for discovery of anti-GBM drugs.
在本文中,我们详细介绍了一系列作为PKM2激活剂的
酚类二聚体的发现及其抗GBM活性的评估。最有前途的化合物5表现出以15 nM的AC50值激活PKM2的高效能,抑制增殖和转移,并诱导GBM细胞凋亡。化合物5可以促进GBM细胞中PKM2的四聚体形成并减少PKM2的核易位,而不影响总PKM2的表达,从而在体外和体内抑制STAT3信号通路。PKM2敲低分析表明5的抗GBM作用主要取决于体外和体内PKM2的表达。化合物16(5的前药)显着抑制了U118肿瘤异种移植的生长并减轻了肿瘤的重量。根据这些调查,
