PKM2-IN-1 is a pyruvate kinase M2 (PKM2) inhibitor with an IC50 of 2.95μM[5].
In MSCs, Increasing the concentration of PKM2-IN gradually promoted adipogenesis confirming the role of PKM2 activity in the TRAF4-mediated inhibition of adipogenic differentiation, 10 μM PKM2-IN increased adipogenesis in the TRAF4-overexpressing group[1]. In the Huh7 cell line, PKM2-IN-1 inhibited CCL20-mediated PKM2 expression and nuclear localization without affecting the phosphorylation of ERK1/2. Furthermore, PKM2-IN-1 inhibited CCL20-mediated aerobic glycolysis and reduced the ability of Huh7 cells to consume glucose and produce lactate and ATP[3].PKM2-IN-1 decreased lactate product and glucose uptake in Eca109 and Ec9706 ?cells[4].PKM2-IN-1 can induce cytotoxicity in HNSCC cells without affecting their glycolysis rate or oxygen consumption[7].PKM2-IN-1 highly increased late apoptosis in U87MG glioma cells without G2-phase arrest[8]
In mice, PKM2-IN-1 treatment markedly decreased the tumor volume and tumor weight, compared with the control group. Meanwhile, no significant weight reduction was detected in the mouse treated with PKM2-IN-1, suggesting that PKM2-IN-1 did not cause any major organ toxicity. Thus, use of specific PKM2 inhibitors to block the glycolytic pathway and target cancer cell metabolism represents a promising therapeutic approach for treating PKM2-overexpressing ovarian cancer[6].In hearts of 7-day-old mice, PKM2-specific inhibitor PKM2-IN-1 significantly blocked the proliferation of cardiomyocytes in HRR groups, indicating HRR-induced proliferation of cardiomyocytes was fully abolished by PKM2-IN-1[2]

在 MSC 中，增加 PKM2-IN 的浓度逐渐促进脂肪生成，证实了 PKM2 活性在 TRAF4 介导的脂肪生成分化抑制中的作用，10 μM PKM2-IN 增加了 TRAF4 过表达组的脂肪生成[1 ]。在 Huh7 细胞系中，PKM2-IN-1 抑制 CCL20 介导的 PKM2 表达和核定位，而不影响 ERK1/2 的磷酸化。此外，PKM2-IN-1 抑制 CCL20 介导的有氧糖酵解并降低 Huh7 细胞消耗葡萄糖和产生乳酸和 ATP 的能力[3]。PKM2-IN-1 减少乳酸产物和葡萄糖摄取在 Eca109 和 Ec9706 细胞[4].PKM2-IN-1 可在 HNSCC 细胞中诱导细胞毒性而不影响其糖酵解速率或耗氧量[7].PKM2-IN- 1 无 G2 期阻滞的 U87MG 神经胶质瘤细胞晚期凋亡显着增加[8]
在小鼠中，与对照组相比，PKM2-IN-1 治疗显着降低了肿瘤体积和肿瘤重量。同时，在用 PKM2-IN-1 处理的小鼠中未检测到明显的体重减轻，表明 PKM2-IN-1 不会引起任何主要器官毒性。因此，使用特定的 PKM2 抑制剂来阻断糖酵解途径和靶向癌细胞代谢是治疗 PKM2 过表达卵巢癌的一种很有前途的治疗方法[6]。在 7 日龄小鼠的心脏中， PKM2 特异性抑制剂 PKM2-IN-1 显着阻断 HRR 组心肌细胞的增殖，表明 PKM2-IN-1 完全消除了 HRR 诱导的心肌细胞增殖[2]
