Mécanisme daction

Caractéristiques	Orally bioavailable mutant-selective EGFR inhibitor that has been tested in Phase III clinical trials for treatment of Non-Small Cell Lung Cancer.
Targets/IC₅₀/Ki	L858R/T790M EGFR (LoVo cells) 11.44 nM Exon 19 deletion EGFR (LoVo cells) 12.92 nM WT EGFR (LoVo cells) 493.8 nM
In vitro	L'AZD9291 montre une inhibition significativement plus puissante de la prolifération dans les lignées cellulaires EGFR mutantes par rapport au type sauvage in vitro.
Essai kinase	Essai de phosphorylation cellulaire de l'EGFR
Essai kinase	Les cellules sont ensemencées (10000 cellules/puits) dans un milieu de croissance dans des plaques Corning noires à fond clair de 384 puits et incubées à 37°C avec 5% de CO₂ pendant la nuit. Les cellules sont dosées acoustiquement à l'aide d'un Echo 555, avec des composés dilués en série dans 100% de DMSO. Les plaques sont incubées pendant 2h supplémentaires, puis après aspiration du milieu, 40 μL de tampon de lyse 1x sont ajoutés à chaque puits. Des plaques Greiner noires à haute liaison de 384 puits sont revêtues d'un anticorps de capture, puis bloquées avec 3% de BSA. Après élimination du bloc, 15 μL de lysat sont transférés dans les plaques Greiner noires à haute liaison de 384 puits et incubés pendant 2 heures. Après aspiration et lavage des plaques avec du PBS, 20 μL d'anticorps de détection sont ajoutés et incubés pendant 2 heures. Après aspiration et lavage des plaques avec du PBS, 20 μL de substrat de peroxydase fluorogène QuantaBlu sont ajoutés et incubés pendant 1 heure. 20 μL de solution d'arrêt QuantaBlu sont ajoutés aux plaques et la fluorescence est lue sur un lecteur de plaques Envision en utilisant une longueur d'onde d'excitation de 352 nm et une longueur d'onde d'émission de 460 nm. Les données obtenues avec chaque composé sont exportées vers un logiciel approprié pour effectuer une analyse d'ajustement de courbe. À partir de ces données, une valeur IC50 est déterminée par le calcul de la concentration du composé nécessaire pour donner un effet de 50 %.
In vivo	AZD9291 (5 mg/kg p.o.) provoque une régression profonde des tumeurs dans les modèles tumoraux EGFRm+ (PC9) et EGFRm+/T790M (H1975) avec une inhibition profonde de la phosphorylation de l'EGFR et des voies de signalisation en aval clés telles que AKT et ERK in vivo.

Foire aux questions

Question 1:
Can this formulation be used in mice? What are its reconstitution instructions for in vivo with mice?

Réponse :
It can be used for animal study. The vehicle we suggest is: 5%DMSO+40%PEG300+5%Tween 80+50%ddH2O.
