R1498

R1498 is a multi-target kinase inhibitor with anti-angiogenic and anti-proliferative activities. R1498 mainly targets targets such as Aurora kinase and VEGFR2, which are associated with tumor development. R1498 showed moderate in vitro growth inhibition in a variety of tumor cells, with IC50 values in the micromolar range. R1498 showed anti-tumor efficacy superior to sorafenib in a variety of gastric cancer and hepatocellular carcinoma xenograft models, with tumor growth inhibition rates exceeding 80%, and tumor shrinkage was observed in some models. R1498 showed a 10-30% tumor shrinkage rate in three xenograft models derived from human primary gastric cancer tumors, further demonstrating its inhibitory potential. R1498 effectively inhibited Aurora A activity in vivo and reduced tumor vascularization.
