Wirkmechanismus

Targets/IC50/Ki
P-gp
(CHrB30 cells)
5.1 nM(Kd)
In vitro

Tariquidar zeigt eine hochaffine Bindung an P-gp mit einem Bmax von 275 pmol/mg. Diese Verbindung zeigt eine nicht-kompetitive Interaktion mit den P-gp-Substraten. Es erhöht die Steady-State-Akkumulation dieser Zytotoxika in CHrB30-Zellen auf Werte, die in nicht-P-gp-exprimierenden AuxB1-Zellen beobachtet werden, mit einer EC50 von 487 nM. Diese Chemikalie ist in der Lage, die Vanadat-sensitive ATPase-Aktivität von P-gp um 60-70% zu hemmen, mit potenten IC50-Werten von 43 nM. Bei höheren Konzentrationen kann es andere Resistenzmechanismen hemmen. 1 µM dieser Verbindung hebt die ABCG2 (BCRP)-vermittelte Resistenz gegen Camptothecine in vitro auf. Es verstärkt die Zytotoxizität mehrerer Medikamente, einschließlich Doxorubicin; eine vollständige Umkehr der Resistenz wird in Gegenwart von 25-80 nM dieser Chemikalie erreicht. In MC26, einer murinen Kolonkarzinom-Zelllinie mit intrinsischer Chemoresistenz, ist die Doxorubicin-IC50 in Gegenwart von 0,1 µM dieser Verbindung fünfmal niedriger (36 vs. 7 nM). In murinen Mammakarzinom-, humanen kleinzelligen Lungenkarzinom- und humanen Ovarialkarzinom-Zelllinien mit erworbener Chemotherapieresistenz (EMT6/AR1.0, H69/LX4 und 2780 AD) ist die In-vitro-Doxorubicin-IC50 in Gegenwart von 0,1 µM dieser Chemikalie 22-150-fach niedriger. Die P-gp-Hemmung bleibt 23 Stunden nach der Entfernung aus dem Kultursystem bestehen. Es stellte die Zytotoxizität von Doxorubicin im National Cancer Institute (NCI)/ADRRES multizellulären Tumorsphäroidmodell wieder her, das von der MCF7WT Brustkrebszelllinie abgeleitet wurde.

Kinase-Assay
Steady-State-Arzneimittelakkumulationsassay
Zellen werden in einem Reaktionsvolumen von 1 ml für 60 min bei 37 °C unter 5% CO2 inkubiert, um den Steady-State zu erreichen. Die Wirkung der Modulatoren XR9576 auf die [3H]-Ligandenakkumulation wird im Konzentrationsbereich von 10-9 - 10-6 M untersucht. Diese Verbindung wird aus einer DMSO-Stammlösung zugegeben, die eine finale Lösungsmittelkonzentration von 0,2 % (v/v) ergibt. Nach der Zellernte wird die akkumulierte Substanz mittels Flüssigszintillationszählung gemessen und auf den Zellproteingehalt normalisiert. Diagramme der akkumulierten Menge als Funktion der Modulatorkonzentration werden mit der allgemeinen Dosis-Wirkungs-Gleichung angepasst: Y={(a-b)/(1+(X/c)d)}+b, wobei: Y=Antwort; a=Anfangsantwort; b=Endantwort; c=EC50-Konzentration; d=Steigungswert; X=Arzneimittelkonzentration.
In vivo

Tariquidar (2-8 mg/kg p.o.) verstärkt nachweislich signifikant die Antitumoraktivität von Doxorubicin (5 mg/kg, i.v.) gegen MC26-Mauskolonkarzinome in vivo. In menschlichen Karzinom-Xenotransplantaten stellte die gleichzeitige Verabreichung dieser Verbindung (6-12 mg/kg p.o.) die Antitumoraktivität gegen zwei hochresistente MDR-menschliche Tumor-Xenotransplantate (2780AD, H69/LX4) in Nacktmäusen vollständig wieder her.

Häufig gestellte Fragen

Frage 1:
Can you please give me more specific and detailed information of how to dissolve and use it (S8028) for in vivo studies?

Antwort:
It in 30% Propylene glycol, 5% Tween 80, 65% D5W at 30mg/ml will be a suspension or emulsion. If you are going to administrate this compound by oral gavage, it is fine. We also have test some vehicles for it for i.p injection, and it is soluble in 5% DMSO+45% PEG 300+ddH2O at 2mg/ml clearly. When preparing the solution, please dissolve it in DMSO clearly first, then add PEG. After they mixed well, then dilute with water.
