Kinase experiment: | 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]. |
Cell experiment: | 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]. |
Animal experiment: | 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℃[1]. |
产品描述 | IC50: 0.0017, 0.021 for Aurora-B/INCENP and Aurora-A/TPX2, respectively Protein kinases Aurora A, B, and C play crucial roles during mitosis and cell division, are frequently elevated in cancer, and represent attractive targets for therapeutic intervention. TAK-901 is a novel, multitargeted Aurora B kinase inhibitor derived from a novel azacarboline kinase hinge-binder chemotype. In vitro: TAK-901 exhibited time-dependent, tight-binding inhibition of Aurora B, but not Aurora A. Consistently, TAK-901 suppressed cellular histone H3 phosphorylation and induced polyploidy. In various human cancer cell lines, TAK-901 inhibited cell proliferation with effective concentration values from 40 to 500 nmol/L. TAK-901 potently inhibited only a few kinases other than Aurora B in intact cells, including FLT3 and FGFR2 [1]. In vivo: In rodent xenografts, TAK-901 exhibited potent activity against multiple human solid tumor types, and complete regression was found in the ovarian cancer A2780 model. In vivo biomarker studies showed that TAK-901 induced PD responses consistent with Aurora B inhibition and correlating with retention of TAK-901 in tumor tissue. [2]. Clinical trials: An open-label, dose escalation, phase I study has been conducted to identify the MTD and PK profile of TAK-901 in adult patients with advanced solid tumors or lymphoma. Reference: |
