| In vitro |
Ispinesib is a potent, allosteric, reversible, and specific inhibitor of KSP, which changes the binding property of KSP to microtubules and disturbs its movement by inhibiting ADP release without altering the release of the KSP-ADP complex from the microtubule. [1] Ispinesib shows potent cytotoxic activity in a panel of tumor cell lines, including Colo205, Colo201, HT-29, M5076, Madison-109, and MX-1, with IC50 of 1.2 nM to 9.5 nM. [2] In PC-3 prostate cancer cells, Ispinesib (15 nM and 30 nM) blocks cell proliferation and induces apoptosis by regulating the expression levels of genes that controls apoptosis, cell proliferation, cell cycle, and cell signaling, such as EGFR, p27, p15, and IL-11. [3] In a panel of 53 breast cell lines, Ispinesib (7.4 nM–600 nM) demonstrates broad inhibitory activity. In BT-474 and MDA-MB-468 cells, Ispinesib (150 nM) induces apoptosis, as revealed by a higher proportion of apoptotic cells, lower antiapoptotic Bcl-XL level, and higher proapoptotic Bax and Bid levels.

| In vivo | Ispinesib (4.5 mg/kg–15 mg/kg) exhibits inhibitory effects against Colo205, Colo201, HT-29, but not MX-1 cells, in mouse xenograft models. SB-715992 (6 mg/kg–10 mg/kg ) also inhibits murine solid tumors, including Madison 109 lung carcinoma, M5076 sarcoma, as well as L1210 and P388 leukemias. [2] In mice xenograft models of breast cancer cells MCF-7, HCC1954, MDA-MB-468, and KPL4, Ispinesib (8 mg/kg–10 mg/kg) inhibits tumor growth. [4] |

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
