| Hazard Information | Back Directory | [Description]
OTS964 is an inhibitor of lymphokine-activated killer T cell-originated protein kinase (TOPK; IC50 = 28 nM). It specifically blocks cytokinesis, leading to apoptosis, in a broad range of cancer cells. OTS964 induces apoptosis of human lung cancer cells in mouse xenografts. | [Uses]
OTS 964 works through cytokinesis and is an effective TOPK inhibitor which has been shown to cause tumor suppression in xenografts of human cancer. | [in vivo]
OTS964 hydrochloride (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 hydrochloride (oral administration; 50 or 100 mg/kg/day for 2 weeks) ultimately 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.
