Description
Curator's Comment: Description was created based on several sources, including http://adisinsight.springer.com/drugs/800025301

BI-2536, an inhibitor of Polo-like kinase 1 (Plk-1) was being investigated by Boehringer Ingelheim as a possible treatment for cancer. BI-2536 inhibits Plk1 enzyme activity at low nanomolar concentrations. The compound potently causes a mitotic arrest and induces apoptosis in human cancer cell lines of diverse tissue origin and oncogenome signature. BI-2536 inhibits growth of human tumor xenografts in nude mice and induces regression of large tumors with well-tolerated intravenous dose regimens. In treated tumors, cells arrest in prometaphase, accumulate phosphohistone H3, and contain aberrant mitotic spindles. This mitotic arrest is followed by a surge in apoptosis, detectable by immunohistochemistry and noninvasive optical and magnetic resonance imaging. For addressing the therapeutic potential of Plk1 inhibition, BI-2536 has progressed into clinical studies in patients with locally advanced or metastatic cancers. It underwent phase II clinical studies for the treatment of breast cancer; non-small cell lung cancer; pancreatic cancer; prostate cancer; small cell lung cancer, but these studies were discontinued later.

Sample Use Guides

200 mg of i.v. BI- 2536, administered once every 3 weeks in patients with advanced metastatic hormone-refractory prostate cancer
Route of Administration: Intravenous
BI-2536 treatment ranging from 10-100 nM leads to the blocking of the recruitment of γ-tubulin and phosphorylation of Apc6 at mitotic centrosomes, inhibition of cohesin release from chromosome arms, induction of monopolar spindles, as well as a range of other mitotic processes, dependent on Plk1 in HeLa cultures.
