JAK2 inhibitor G5-7 是具有口服活性的JAK2变构抑制剂，可通过结合到 JAK2，选择性的抑制JAK2介导的 EGFR 和 STAT3 的磷酸化和激活。它诱导细胞周阻滞和诱导凋亡、具有抗血管生成活性。它有用于胶质瘤研究的潜能。

JAK2 inhibitor G5-7 is an orally active JAK2 inhibitor, selectively inhibits JAK2–mediated phosphorylation and activation of EGFR (Tyr1068) and STAT3 by binding to JAK2. G5-7 has the potential for glioma study

G5-7 that selectively inhibited Janus kinase 2 (JAK2)-mediated phosphorylation and activation of EGFR and STAT3 (signal transducer and activator of transcription 3) by binding to JAK2, thereby decreasing the activity of downstream signaling by mTOR (mammalian target of rapamycin) and inducing cell cycle arrest.?G5-7 inhibited the proliferation of PTEN-deficient glioblastoma cell lines harboring a constitutively active variant of EGFR (U87MG/EGFRvIII) and human glioblastoma explant neurosphere cultures, but the drug only weakly inhibited the proliferation of either glioblastoma cell lines that were wild type for EGFR and stably transfected with PTEN (U87MG/PTEN) or normal neural progenitor cells and astrocytes.?Additionally, G5-7 reduced vascular endothelial growth factor (VEGF) secretion and endothelial cell migration and induced apoptosis in glioblastoma xenografts, thereby suppressing glioblastoma growth in vivo.?Furthermore, G5-7 was more potent than EGFR or JAK2 inhibitors that interfere with either ligand or adenosine 5'-triphosphate (ATP) binding at impeding glioblastoma cell proliferation.
