Inhibitor that binds Hec1, inhibiting its association with Nek2 and kinetochores. Causes arrest of mitosis and inhibits proliferation in breast cancer cell lines (GI50= 10-20 μM).
Shown to induce a transient mitotic arrest in HeLa cultures and inhibit the proliferation of 10 breast cancer cell lines (GI50 of 10-21 µM) as well as the cervical HeLa and colon HCT116 cancer lines, while exhibiting reduced potency against the noncancerous MCF10A line (GI50 = 41 µM). Reported to suppress the MDA-MB-468-derived tumor growth (by ~53% and ~75% 3 wks after a 7-wk treatment period with 50 mg/kg and 100 mg/kg INH1, repectively, i.p.) in a murine breast cancer model in vivo.
