OTS514 is a highly potent TOPK inhibitor with an IC 50 of 2.6 nM. OTS514 strongly suppresses the growth of TOPK-positive cancer cells OTS514 induces cell cycle arrest and apoptosis . In Vitro OTS514 (1.5625-100 nM) induces cell cycle arrest and apoptosis at nanomolar concentrations in a series of human myeloma cell lines (HMCL) and prevents outgrowth of a putative CD138 + stem cell population from multiple myeloma (MM) patient-derived peripheral blood mononuclear cells. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: Human myeloma cell lines (MM1.S, MM1.R, RPMI 8226, 8226Dox40, KMS34, KMS34CFZ, KMS11, JJN3, LP-1, NCI H929, U266B1) Concentration: 1.5625, 3.125, 6.25, 12.5, 25, 50, and 100 nM Incubation Time: 72 hours Result: IC 50 values ranged from 11.6 to 29.4 nM in parental cell lines, indicating a potent inhibitory effect. Only the RPMI 8226-Dox40 cell line, which overexpresses the multi-drug resistance transporter gene ABCB1, is resistant. In Vivo OTS514 (1-5 mg/kg; once a day for 2 weeks; intravenous administration) induces tumor regression in a xenograft model of A549 cells (TOPK-positive lung cancer cells) . MCE has not independently confirmed the accuracy of these methods. They are for reference only. Animal Model: Female BALB/cSLC-nu/nu mice bearing a xenograft model of A549 cells Dosage: 1, 2.5, and 5 mg/kg Administration: Intravenously treated; once every day for 2 weeks Result: Resulted in tumor growth inhibition (TGI) of 5.7, 43.3, and 65.3% on day 15, respectively, without any body weight loss. IC50& Target:IC50: 2.6 nM (TOPK)

OTS514 是一种强效 TOPK 抑制剂，其 IC 50 为 2.6 nM。OTS514 能强烈抑制 TOPK 阳性癌细胞的生长。OTS514 可诱导细胞周期停滞和细胞凋亡。
