Herein we report the discovery of a novel series of highly potent and selective mitogen-activated protein kinase kinase 4 (MEK4) inhibitors. MEK4 is an upstream kinase in MAPK signaling pathways that phosphorylates p38 MAPK and JNK in response to mitogenic and cellular stress queues. MEK4 is overexpressed and induces metastasis in advanced prostate cancer lesions. However, the value of MEK4 as an oncology
在这里,我们报告发现了一系列新型的高效和选择性促分裂原活化蛋白激酶激酶4(MEK4)
抑制剂。MEK4是
MAPK信号通路中的上游激酶,可响应促有丝分裂和细胞应激反应而使p38
MAPK和JNK
磷酸化。MEK4过度表达,并在晚期前列腺癌病变中诱导转移。然而,由于尚未开发出靶向MEK4的选择性
化学探针,因此MEK4作为肿瘤靶标的价值尚未得到药理学验证。通过结构-活性关系和分子建模对该系列的优化导致鉴定了化合物6 ff(4-(6-
氟-2H-
吲唑-3-基)
苯甲酸),这是一种高效且选择性的MEK4
抑制剂。
