TAK-901

Enzyme activities of Aurora A/TPX2 and Aurora B/INCENP complexes are assayed at room temperature in buffer containing serially diluted TAK-901, and the product is quantified using IMAP detection reagents. Aurora A/TPX2 (2 nM) is assayed with 100 nM FL-Kemptide and 1 mM ATP. Aurora B/INCENP (0.8 nM) is assayed with 100 nM 5-carboxy-fluorescein-GRTGRRNSI-NH2 (FL-PKAtide) and 10 mM ATP. For time-dependent inhibition, Aurora B/INCENP is incubated with TAK-901 for 1 hour at room temperature followed by addition of 150 mM ATP to initiate the reaction^[1].

Cells are plated in 96-well microtiter plates and incubated with serial dilutions of TAK-901 for 72 hours. Cell proliferation is determined by ELISA analysis of bromodeoxyuridine (BrdUrd) incorporation into DNA. IMR-90 immortalized lung fibroblasts are seeded in 96-well microtiter plates and cultured for 3 to 4 days until confluent. Cells are then incubated with serial dilutions of TAK-901 for 72 hours. The MTS assay is conducted^[1].

Mice: Tumor-bearing mice or rats are treated intravenously twice daily (b.i.d.) with either vehicle or TAK-901 on 2 consecutive days per week or every other day for 2 or 3 cycles. The antitumor activity of TAK-901 in human tumor and leukemia xenograft models are monitored^[1].

Nude rats bearing A2780 tumors averaging 250 to 500 mg receive an intravenous dose of TAK-901. Plasma samples are collected by terminal cardiac puncture under CO₂ anesthesia. Tumors are dissected and snap-frozen at -80°C^[1].
