| In vitro |
Canertinib (CI-1033) shows excellent potency for irreversible inhibition of erbB2 autophosphorylation in MDA-MB 453 cells, and also demonstrates high permeability in Caco-2 cells. This compound alone significantly suppresses constitutively activated Akt and MAP kinase, and in combination inhibits Akt while preventing increased levels of MAPK phosphorylation. It stimulates p27 expression and p38 phosphorylation in MDA-MB-453 cells. CI-1033 is highly specific to the erbB receptor family and not sensitive to PGFR, FGFR or IR even at 50 μM. It shows high levels of inhibition in A431 cells expressing EGFR with IC50 of 7.4 nM, and suppresses heregulin-stimulated tyrosine phosphorylation of erbB2, erbB3 and erbB4 with IC50 of 5, 14 and 10 nM, respectively. The compound also inhibits expression of pp62c-fos in response to heregulin. It is predicted to modify Cys773 covalently within the ATP binding site of the HER2 kinase and enhances destruction of both mature and immature ErbB-2 molecules. This compound induces a significant decrease in measurable phosphorylation of tyrosine residues 845 and 1068 of EGFR, which are responsible for Src and Ras/MAPK signaling respectively. The corresponding residues of Her-2, tyrosine residues 877 and 1248 are dephosphorylated significantly by it at a concentration of 3 μM or higher. CI could block EGFR internalization and increase the rate of apoptosis in primary osteosarcoma cells in a titratable fashion. In addition, it inhibits the proliferation of TT, TE2, TE6 and TE10 cells significantly at 0.1 nM. |

Los ensayos enzimáticos para la determinación de la IC50 se realizan en placas de filtro de 96 pocillos en un volumen total de 0,1 mL, que contienen 20 mM de Hepes, pH 7,4, 50 mM de vanadato de sodio, 10 μM de ATP que contiene 0,5 mCi de [32P]ATP, 20 mg de ácido poliglutámico/tirosina, 10 ng de EGFR tyrosine kinase, y diluciones apropiadas de Canertinib (CI-1033). Todos los componentes excepto el ATP se añaden al pocillo y la placa se incuba con agitación durante 10 min a 25 °C. La reacción se inicia añadiendo [32P]ATP, y la placa se incuba a 25 °C durante otros 10 min. La reacción se termina añadiendo 0,1 mL de ácido tricloroacético (TCA) al 20%. La placa se mantiene a 4 °C durante al menos 15 min para permitir que el sustrato precipite. Los pocillos se lavan cinco veces con 0,2 mL de TCA al 10% y la incorporación de 32P se determina con un contador de placas Wallac β.

| In vivo |
Canertinib (CI-1033) shows impressive activity against A431 xenografts in nude mice at 5 mg/kg of body weight. This compound (20 to 80 mg/kg/d) achieves a high degree of tumor regressions in H125 xenograft models. Its oral administration causes a marked inhibition of growth in TT, TE6 and TE10 xenografts in nude mice, without animal death and <10% weight loss. |

Pregunta 1:
I would like to know which is the best option/solvent to dilute it for in vivo experiments. (I am treating mice at 30mg/mL of this compound.)
Respuesta:
It is a suspension in the formulation recommended (30% Propylene glycol, 5% Tween 80, 65% D5W) on our product page at 30mg/ml. It’s fine for oral gavage.
