been disclosed, but very few Hippo pathway activators are reported. Here, we discovered a new class of Hippo pathway activator, YL-602, which inhibited expression in cells irrespective of cell density and the presence of serum. Mechanistically, YL-602 activates the Hippo pathway via MST1/2, which is different from known activators of Hippo pathway. , YL-602 significantly induced tumor cell apoptosis and
Hippo 通路是组织生长、器官大小和肿瘤发生的关键调节因子。通过基因编辑或药物干预激活Hippo通路已被证明是治疗Hippo通路依赖性癌症的新治疗策略。目前,已有多种直接靶向Hippo通路下游效应蛋白的化合物,包括YAP和TEADs等,但Hippo通路激活剂的报道还很少。在这里,我们发现了一类新的 Hippo 通路激活剂 YL-602,无论细胞密度和血清是否存在,它都能抑制细胞中的表达。从机制上讲,YL-602通过MST1/2激活Hippo途径,这与已知的Hippo途径激活剂不同。 、YL-602显着诱导肿瘤细胞凋亡并抑制肿瘤细胞集落形成。口服YL-602通过激活Hippo途径显着抑制癌细胞的生长。总体而言,YL-602 可能是一种有前途的先导化合物,其作用机制和治疗应用值得进一步研究。
