| Hazard Information | Back Directory | [Uses]
OTS964 is an orally active, high affinity and selective TOPK inhibitor with an IC50 of 28 nM[1]. OTS964 is also a potent inhibitor of the cyclin-dependent kinase CDK11, which binds to CDK11B with a Kd of 40 nM[2]. | [in vivo]
OTS964 (intravenously; 40 mg/kg on days 1, 4, 8, 11, 15, and 18) makes tumors shrinking even after the treatment and finally revealing complete regression[1].
OTS964 (oral administration; 50 or 100 mg/kg/day for 2 weeks) achieves complete tumor regression[1]. | Animal Model: | Nude mice bearing LU-99 lung cancer cells[1] | | Dosage: | 40 mg/kg | | Administration: | Intravenously; on days 1, 4, 8, 11, 15, and 18 | | Result: | The tumors continued shrinking even after the treatment and finally revealed complete regression.

| Animal Model: | Nude mice bearing LU-99 lung cancer cells[1] | | Dosage: | 50 or 100 mg/kg | | Administration: |
Oral administration; once every day for 2 weeks | | Result: | Achieved complete tumor regression.
