Ispinesib (SB 715992) is a potent mitotic kinesin KSP (Eg5) inhibitor with a Ki and an IC50 of 0.6 and 4.1 nM, respectively. Ispinesib (SB 715992) has cytotoxic activity at less than 10 nM in a spectrum of tumor cell lines. Ispinesib (SB 715992) is negative in a mouse model of peripheral neuropathy in which paclitaxel is positive. Ispinesib (SB 715992) was shown to have activity against advanced human colon tumor xenografts including: Colo205 (complete regressions), Colo201 (complete regressions), and HT-29 (tumor growth delay). Ispinesib (SB 715992) (10 mg/kg) induced unexplained toxicity in mice bearing osteosarcoma xenografts. Ispinesib (SB 715992) enhanced the antitumor activity of trastuzumab, lapatinib, doxorubicin, and capecitabine and exhibited activity comparable with paclitaxel and ixabepilone.
