Catalog Number: 5408
Alternate Names: SB 715992
Chemical Name: N-(3-Aminopropyl)-N-[(1R)-1-[7-chloro-3,4-dihydro-4-oxo-3-(phenylmethyl)-2-quinazolinyl]-2-methylpropyl]-4-methylbenzamide
Biological Activity
High affinity allosteric kinesin spindle protein (KSP) inhibitor (Ki app = 1.7 nM). Exhibits >10,000-fold selectivity for KSP over a range of other mitotic kinesins. Inhibits proliferation and induces apoptosis of prostate and breast cancer cells in vitro. Induces tumor regression of breast cancer cell xenografts in mice.
