allosteric site. Among the derivatives, compound 8t was selected for further study, with IC50 values of 0.25 and approximately 5 μM in enzymatic and cell-based assays, respectively. Mechanistically, compound 8t reduced the glycolysis and oxygen consumption rate in cancer cells, which led to decreased adenosine 5′-triphosphate (ATP) production and subsequent 5′ adenosine monophosphate-activated protein kinase
磷酸甘油酸突变酶1(PGAM1)通过调节其底物3-磷酸甘油酸酯(3 PG)和产物2-磷酸甘油酸酯(2 PG)来协调糖酵解,磷酸戊糖途径和丝氨酸合成,从而促进肿瘤生长。在此,基于我们先前报道的PGAM1抑制剂PGMI-004A,我们开发了蒽醌衍生物作为新型变构PGAM1抑制剂,并研究了结构-活性关系(SAR)。此外,我们确定了PGAM1和抑制剂8g的共晶体结构,表明该抑制剂位于一个新的变构位点。在衍生物中,选择了化合物8t进行进一步研究,其IC 50为的0.25值和大约5 μ在酶和基于细胞的测定,分别用M。从机理上讲,化合物8t降低了癌细胞中的糖酵解和耗氧率,从而导致腺苷5'-三磷酸(ATP)生成减少,随后5'腺苷单磷酸激活的蛋白激酶(AMPK)激活。抑制剂8t在H1299异种移植模型中也显示出良好的延迟肿瘤生长的功效,而没有明显的毒性。综上所述,这项原则性的工作进一步验证了PGAM1作为
