Wirkungsmechanismus (Mechanism of Action)

Eigenschaften	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.
Kinase-Assay	Enzymassays
Kinase-Assay	Kinase-Reaktionen werden in einem finalen Assay-Volumen von 10 μL unter Verwendung des Z-Lyte Assay-Kits (Ser/Thr Peptid 16) durchgeführt. Kurz gesagt, die Reaktionen enthalten 50 mM HEPES (pH 7,5), 10 mM MgCl₂, 1 mM EGTA, 1 mM DTT, 0,01% Brij 35, 0,01 mg/mL Casein, 200 μM ATP, 200 μM Polo Box Peptid (NH₂-MAGPMQS[pT]PLNGAKK-OH) und 6 nM rekombinantes Plk1 (H6-tev-PLK 1-603). Plk1 wird für 60 Minuten mit 0 bis 1 μM GSK461364 vorinkubiert. Die Reaktionen werden dann durch Zugabe von 2 μM Peptid initiiert. Nach 15 Minuten bei 23 °C werden die Reaktionen abgebrochen und gemäß dem Z′-Lyte-Protokoll verarbeitet und auf einem EnVision-Plattenleser abgelesen. Rohe Fluoreszenzwerte werden unter Verwendung von Substrat- und Produktstandards in die Konzentration des gebildeten Produkts umgewandelt. Da die Hemmwirkung dieser Verbindung als Funktion der ATP-Konzentration auf eine Weise variiert, die mit einem ATP-kompetitiven Hemmungsmodus übereinstimmt, wird eine Obergrenze für den K_i dieser Chemikalie bestimmt.
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.
