GSK547 (GSK'547) 是一种高效的选择性receptor-interacting serine/threonine protein kinase 1 (RIPK1)抑制剂,可抑制巨噬细胞介导的胰腺癌适应性免疫耐受。
生物活性 | GSK547 (GSK'547) is a highly selective and potent inhibitor ofreceptor-interacting serine/threonine protein kinase 1 (RIPK1), inhibits macrophage-mediated adaptive immune tolerance in pancreaticcancer[1]. |
IC50& Target | |
体外研究 (In Vitro) | GSK547 (0.1-100000 nM; 24 hours) pretreats L929 cells with recombinant TNFα and zVAD at various doses for 30 min, then cell death is induced with an IC50of 32 nM after 24 hours[1]. GSK547 up-regulates STAT1 signaling in bone marrow-derived macrophages (BMDM)[1].
Cell Viability Assay[1] Cell Line: | L929 cells (Mouse L-cells NCTC 929) | Concentration: | 0.1 nM; 10 nM; 1000 nM; 100000 nM | Incubation Time: | 24 hours | Result: | Reduced viability of L929 cells after co-treatment with TNFα and zVAD with an IC50of 32 nM. |
Western Blot Analysis[1] Cell Line: | Bone marrow-derived macrophages (BMDM) | Concentration: | | Incubation Time: | 30 minutes | Result: | Up-regulated STAT1 signaling in BMDM. |

体内研究 (In Vivo) | GSK547 (GSK′547; RIP1i) robustly targets RIP1 in vivo. RIP1 inhibition results in immunogenic macrophage differentiation in pancreatic cancer, leading to adaptive immune activation and tumor protection for pancreatic ductal adenocarcinoma (PDA)[1]. GSK547 (100 mg/kg/day; fed via food-based dosing; 15-50 days) reduces tumor burden and extends survival compared with mice treated with controls or Nec-1s[1].
Animal Model: | The wild-type (WT) mice orthotopically implanted withPdx1Cre;KrasG12D;Trp53R172H(KPC)-derived tumor cells[1] | Dosage: | ~100 mg/kg | Administration: | Fed via food-based dosing, daily, 15-50 days | Result: | Reduced tumor burden and extended survival. |
