靶点 |

描述 | The JAK/STAT3 pathway is activated by various cancer types, including glioma, and blockade of the pathway induces cell death in cancer cells. JAKs encompass a family of four (JAK1, JAK2, JAK3 and TYK2) intracellular, non-receptor tyrosine kinases, associated with cytokine receptors. Under normal conditions, activation of the receptor by cytokine binding leads to trans-phosphorylation of JAK and downstream phosphorylation of STAT proteins (pSTAT)[3]. JAK2 phosphorylates cell surface receptors on tyrosine residues creating docking sites for STAT3 proteins. Once STAT3 is recruited to the receptor, it is phosphorylated by JAK2 allowing STAT3 to form a dimer and move into the nucleus where it can activate the transcription of target genes[4]. Pacritinib is a JAK2 and fms-like tyrosine kinase-3 (FLT3) inhibitor with IC50 23 nM and 22 nM. It also suppresses the interleukin-1-directed inflammatory pathway via inhibition of interleukin 1 receptor-associated kinase 1 (IRAK1)[5]. In a phase I study, thirteen AML (acute myeloid leukemia) patients were enrolled, treated with Pacritinib at a dose of 100 mg or 200 mg twice daily following a 3 + 3 dose-escalation in combination with cytarabine and daunorubicin or with decitabine induction. The result demonstrated that pacritinib was well tolerated and had preliminary anti-leukemic activity[6]. In a vivo study, the Stelic animal model (STAM) mouse were given 200 mg/kg Pacritinib orally for twice a day for 10 days. Pacritinib-treated mice had significantly reduced fibrotic areas in liver compared to vehicle control and significantly lower levels of CK18 which demonstrated that pacritinib possess a good antifibrotic effect[7]. Thirty-two mice were xenografted with BT147(brain tumor initiating cells) cells, and treated with pacritinib at a dose of 100 mg/kg. Pacritinib resulted in an increase median survival of 62.5 days which demonstrated pacritinib synergy with TMZ may be another considerable choice therapy for GBM(glioblastoma multiforme)[4]. |
