| Outline of Final Research Achievements |
Among the novel synthetic KSP inhibitors, KPYB 10602 has the highest inhibitory effect on cell proliferation against human breast cancer cell lines, and its effect was highest in MDA-MB-231 cells. The KPYB10602 treatment was shown to result in induction of mitotic arrest with distinct monopolar spindle formation and then apoptotic cell death. KPYB10602 also effectively suppressed tumor growth in a subcutaneous xenograft model. In conclusion, KSP is a good target for breast cancer chemotherapy, and KPYB10602 has a potential as a novel anti-cancer agent for breast cancer.
