Mécanisme d'action (Mechanism of Action)

Caractéristiques	Demonstrates >390-fold selectivity for Plk1 relative to Plk2 and Plk3.
Targets/IC₅₀/Ki	PLK1 (Cell-free assay) 2.2 nM(Ki)
In vitro	GSK461364 inhibits cancer cell line proliferation from multiple origins with minimal toxicity in nondividing human cells. RNA silencing of WT p53 increases the antiproliferative activity of this compound. As many cancer therapies tend to be more effective in p53 WT patients, the higher sensitivity of p53-deficient tumors toward this chemical could potentially offer an opportunity to treat tumors that are refractory to other chemotherapies as well as early line therapy for these genotypes. This compound is a thiophene amide that inhibits purified Plk1 enzyme in vitro with a K_i of 2 nM and has >100-fold selectivity for Plk1 compared with Plk2 and Plk3. It is a potent inhibitor of cell proliferation causing 50% growth inhibition (GI50) below 100 nM in most of the cell lines tested with limited toxicity against human nonproliferating cells. Inhibition of cell cycle progression is concentration dependent with initial delay at G2 phase at high concentrations of this agent and arrest at M phase at lower concentrations. Currently, it is in a dose-escalation first-time-in-human trial. Cell lines with mutations in the TP53 gene tended to be more sensitive to this compound, and that inhibiting the p53 response by RNA silencing confers increased sensitivity in some p53 wild-type (WT) cells. Furthermore, these more sensitive cell lines also have increased levels of chromosome instability, a characteristic associated with TP53 mutations. In preclinical testing, this chemical shows antiproliferative activity against multiple (>120) tumor cell lines and potently inhibits the proliferation of greater than 83% and 91% of these cell lines, with IC50 values lower than 50 and 100 nM, respectively.
Essai kinase	Essais enzymatiques
Essai kinase	Les réactions de kinase sont effectuées dans un volume d'essai final de 10 μL à l'aide du kit d'essai Z-Lyte (peptide Ser/Thr 16). En bref, les réactions contiennent 50 mM HEPES (pH 7,5), 10 mM MgCl₂, 1 mM EGTA, 1 mM DTT, 0,01 % Brij 35, 0,01 mg/mL de caséine, 200 μM d'ATP, 200 μM de peptide Polo Box (NH₂-MAGPMQS[pT]PLNGAKK-OH) et 6 nM de Plk1 recombinant (H6-tev-PLK 1-603). Plk1 est préincubée pendant 60 minutes avec 0 à 1 μM de GSK461364. Les réactions sont ensuite initiées par l'ajout de 2 μM de peptide. Après 15 minutes à 23 °C, les réactions sont stoppées et traitées selon le protocole Z'-Lyte et lues sur un lecteur de plaques EnVision. Les valeurs de fluorescence brutes sont converties en concentration de produit formé à l'aide de standards de substrat et de produit. Étant donné que la puissance d'inhibition de ce composé est observée varier en fonction de la concentration d'ATP d'une manière compatible avec un mode d'inhibition compétitif de l'ATP, une limite supérieure pour le K_i de cette substance chimique est déterminée.
In vivo	Cell culture growth inhibition by GSK461364 can be cytostatic or cytotoxic but leads to tumor regression in xenograft tumor models under proper dose scheduling. This compound shows clear antitumor activity in human tumor xenograft models. It shows a dose-dependent mitotic arrest in mouse xenografts, which correlates with effects on tumor growth. Intraperitoneal administration of this chemical causes regression or tumor growth delay in different xenograft models, including Colo205 xenografts. Suppression of Plk1 in vivo by using this agent results in mitotic arrest with aberrant mitotic figures consisting of monopolar or collapsed mitotic spindles.
