GSK547 Usage And Synthesis

Biological Activity

GSK'547 is a highly selective and potent inhibitor of RIP1 (RIPK1) with a 400-fold increase in oral exposure compared to GSK'963 in mouse pharmacokinetic studies.

in vitro

In vitro, treatment with GSK'547 directed bone marrow-derived macrophages to develop an immunogenic phenotype, with up-regulation of MHC-II, TNFa and IFNg expression, and decreased CD206, IL- 10 and TGFb expression. In addition, it also up-regulated STAT1 signaling and decreased STAT3, STAT5 and STAT6 signaling in bone marrow-derived macrophages. Macrophages treated with GSK'547 had stronger ability to capture antigens.

in vivo

Mice were given GSK'547 through food, the concentration of GSK'547 in vivo was stable within 24 hours, which was higher than the IC50 value in L929 cells. GSK'547 maintained high concentrations in vivo during the 6-week administration. GSK'547 was well tolerated with no obvious pathological features. In mice with in situ pancreatic ductal adenocarcinoma, It reduced tumor burden and prolonged survival compared to control and Nec-1s-treated groups. GSK'547 prevents established tumors and liver metastases.
