LY294002 PI3K Inhibitor

Kat.-Nr.S1105

LY294002 (SF 1101, NSC 697286) ist das erste synthetische Molekül, das PI3Kα/δ/β mit einer IC50 von 0,5 μM/0,57 μM/0,97 μM hemmt; es ist in Lösung stabiler als Wortmannin und blockiert auch die Autophagosomenbildung. Es bindet nicht nur an Klasse-I-PI3Ks und andere PI3K-verwandte Kinasen, sondern auch an neuartige Ziele, die scheinbar nicht zur PI3K-Familie gehören. Diese Verbindung hemmt auch CK2 mit einer IC50 von 98 nM. Es ist ein nicht-spezifischer DNA-PKcs-Inhibitor und aktiviert Autophagy und Apoptosis.

In vitro

LY294002 ist nicht ausschließlich selektiv für die PI3Ks und könnte tatsächlich auf andere Lipidkinasen und zusätzliche scheinbar unabhängige Proteine wirken. Diese Verbindung hemmt nicht nur mTOR und DNA-PK, sondern auch andere Proteinkinasen, wie CK2 (Casein Kinase 2) und Pim-1. Es inaktiviert Akt/PKB, wodurch die Zellproliferation gehemmt und Apoptosis induziert wird. Diese Chemikalie zeigt eine bemerkenswerte wachstumshemmende und Apoptosis-induzierende Wirkung in diesen Darmkrebszelllinien, mit einer verringerten Expression von phosphoryliertem Akt (Ser473). Sie induziert eine ausgeprägte nukleäre Pyknose und ein vermindertes zytoplasmatisches Volumen in den Tumorzellen. Daher hemmt diese Verbindung die Proliferation von Eierstockkrebszellen in vitro erheblich. Sie induziert einen spezifischen G1-Arrest im Zellwachstum, was zu einer nahezu vollständigen Hemmung der Melanomzellproliferation und einer teilweisen Hemmung der MG-63 (Osteosarkomzelllinie)-Proliferation führt. Die Wirkung dieser Chemikalie auf den Zellzyklusfortschritt könnte Einblicke in eine mögliche Verbindung zwischen dem PI3K-Aktivierungsweg und der Krebszellzyklusregulation geben.

Kinase-Assay
Kinase-Assays
Die PI3K-Hemmung durch LY294002 wird in einem radiometrischen Assay unter Verwendung von gereinigten, rekombinanten Enzymen mit 1 μM ATP bestimmt. Die Kinase-Reaktion wird 1 Stunde bei Raumtemperatur (24oC) durchgeführt und durch Zugabe von PBS beendet. Die IC50-Werte werden anschließend mithilfe einer sigmoidalen Dosis-Wirkungs-Kurvenanpassung (variable Steigung) bestimmt. Die CK2- und GSK3β (Glykogen-Synthase-Kinase 3β)-Hemmung wird durch ein Kinase-Selektivitäts-Screening ermittelt. Diese Verbindung wird gegen das Upstate-Panel von Kinasen in 10 μM ATP getestet.
In vivo

LY294002 führt auch zur Unterdrückung des Tumorwachstums und zur Induktion von Apoptosis, insbesondere bei den LoVo-Tumoren, und zeigt daher eine bemerkenswerte Wirksamkeit im Mausmodell der Peritonitis carcinomatosa. Diese Verbindung hemmt signifikant das Wachstum und die Aszitesbildung von Eierstockkarzinomen.

Häufig gestellte Fragen

Frage 1:
