Like BI2536, BI6727 is an ATP-competitive kinase inhibitor from the dihydropteridinone class of compounds. In addition to Plk1, BI6727 also potently inhibits two closely related kinases Plk2 and Plk3 with IC50 of 5 nM and 56 nM, respectively. BI6727 at concentrations up to 10 μM displays no inhibitory activity against a panel of >50 other kinases. BI6727 inhibits the proliferation of multiple cell lines derived from various cancer tissues, including HCT116, NCI-H460, BRO, GRANTA-519, HL-60, THP-1, and Raji cells with EC50 of 23 nM, 21 nM, 11 nM, 15 nM, 32 nM, 36 nM, and 37 nM, respectively. BI6727 treatment (100 nM) in NCI-H460 cells induces an accumulation of mitotic cells with monopolar spindles and positive staining for histone H3 phosphoserine 10, confirming that cells are arrested early in the M phase, followed by induction of apoptosis. [1] Low nanomolar concentrations of BI6727 display potent inhibitory activity against neuroblastoma (NB) tumor-initiating cells (NB TIC) with EC50 of 21 nM, whereas only micromolar concentrations of BI6727 are cytotoxic for normal pediatric neural stem cells. [2] BI6727 induces growth arrest of Daoy and ONS-76 medulloblastoma cells similar to BI 2536. [3] |

| In vivo | Administration of BI6727 significantly inhibits the growth of multiple human carcinoma xenografts including HCT116, NCI-H460, and taxane-resistant CXB1 colon carcinoma, accompanied by an increase in the mitotic index as well as an increase in apoptosis. [1] In in vivo studies, BI6727 shows better toxicity and pharmacokinetic profile compared to BI2536. [3] |

Frequently Asked Questions
Question 1:
I wonder how to reconstitute the inhibitor for in vivo studies?
Answer:
Volasertib can be dissolved in 4% DMSO+Corn oil at 2mg/ml for i.p. injection in mice. For oral administration, it can be formulated in hydrochloric acid (0.1 N), and diluted with 0.9% NaCl, or suspended in 0.5% Natrosol 250 hydroxyethyl-cellulose as indicated in the publications. We also suggest the vehicle 30% PEG400/0.5% Tween80/5% propylene glycol for a suspension which we tested in house.
