OTS514（Cat No.:I001292） is a highly potent inhibitor of T-lymphokine-activated killer cell-derived protein kinase (TOPK). TOPK plays a crucial role in cancer cell proliferation and the maintenance of cancer stem cells. By inhibiting TOPK, OTS514 effectively disrupts these processes, offering potential therapeutic benefits against cancer. Additionally, OTS514 downregulates the expression of the oncogenic transcription factor forkhead box protein M1 (FOXM1), further contributing to its anticancer effects.
