Metodo per preparare il liquido master di DMSO: mg farmaco predissolto in μL DMSO ( Concentrazione del liquido master mg/mL, Vi preghiamo di contattarci prima se la concentrazione supera la solubilità del DMSO del lotto del farmaco. )
Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungereμL PEG300, mescolare e chiarire, quindi aggiungereμL Tween 80, mescolare e chiarire, quindi aggiungere μL ddH2O, mescolare e chiarire.
Metodo per preparare la formulazione in vivo: Prendere μL DMSO liquido master, quindi aggiungere μL Olio di mais, mescolare e chiarire.
Nota: 1. Si prega di assicurarsi che il liquido sia limpido prima di aggiungere il solvente successivo.
2. Assicurarsi di aggiungere il/i solvente/i in ordine. È necessario assicurarsi che la soluzione ottenuta, nell'aggiunta precedente, sia una soluzione limpida prima di procedere all'aggiunta del solvente successivo. Metodi fisici come il vortex, gli ultrasuoni o il bagno d'acqua calda possono essere utilizzati per facilitare la dissoluzione.

| 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. |

I saggi enzimatici per la determinazione dell'IC50 vengono eseguiti in piastre filtranti a 96 pozzetti in un volume totale di 0,1 mL, contenente 20 mM Hepes, pH 7,4, 50 mM vanadato di sodio, 10 μM di ATP contenente 0,5 mCi di [32P]ATP, 20 mg di acido poliglutamico/tirosina, 10 ng di EGFR tyrosine kinase, e diluizioni appropriate di Canertinib (CI-1033). Tutti i componenti tranne l'ATP vengono aggiunti al pozzetto e la piastra viene incubata con agitazione per 10 min a 25 °C. La reazione viene avviata aggiungendo [32P]ATP, e la piastra viene incubata a 25 °C per altri 10 min. La reazione viene terminata con l'aggiunta di 0,1 mL di acido tricloroacetico (TCA) al 20%. La piastra viene mantenuta a 4 °C per almeno 15 min per consentire al substrato di precipitare. I pozzetti vengono quindi lavati cinque volte con 0,2 mL di TCA al 10% e l'incorporazione di 32P viene determinata con un contatore di piastre 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. |

Domanda 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.)
Risposta:
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.
