Passo 1: Inserire le informazioni di seguito (Consigliato: Un animale aggiuntivo per tenere conto della perdita durante l'esperimento)
Passo 2: Inserire la formulazione in vivo (Questo è solo il calcolatore, non la formulazione. Contattateci prima se non c'è una formulazione in vivo nella sezione Solubilità.)
Risultati del calcolo:
Concentrazione di lavoro: mg/ml;
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 |
In nonclinical studies, Prexasertib HCl (LY2606368) induced DNA damage as measured by replication catastrophe and increases in pH2A.X, a marker of double-stranded DNA breaks. Treatment of cells with this compound results in the rapid appearance of TUNEL and pH2AX-positive double-stranded DNA breaks in the S-phase cell population. In a functional assay, it potently abrogated the G2–M checkpoint activated by doxorubicin in p53-deficient HeLa cells with an EC50 of 9 nmol/L. It was broadly antiproliferative with IC50 values typically <50 nmol/L in the most sensitive cell lines with a minority of cell lines showing considerable resistance with IC50's >1,000 nmol/L. This compound requires CDC25A and CDK2 to cause DNA damage. |
| In vivo |
Prexasertib HCl (LY2606368) inhibited tumor growth in cancer xenografts as monotherapy and in combination with other agents. In an orthotopic SKOV3 ovarian cancer model, it was shown to inhibit the growth of primary tumors and significantly reduce the incidence of metastases and ascites accumulation. This compound also demonstrated efficacy in an SW1990 orthotopic pancreatic cancer model resulting in a 92% inhibition of primary tumor growth and the elimination of metastases to the lymphnode, spleen, and intestine. |

Domanda 1:
Would you please suggest a suitable vehicle to dissolve it for in vivo use?
Risposta:
It can be dissolved in a vehicle: 5% DMSO+40%PEG 300+5%Tween80+ddH2O for in vivo use in mice (i.p.). This stock concentration reaches 10mg/ml, and can be prepared for work solution as 0.5mg/ml, stable for no longer than 30min.
Domanda 2:
What is the solubility of it in 20% Captisol?
Risposta:
It is a suspension in 20% Captisol, which is fine for oral gavage. You can dissolve this compound in this vehicle to the concentration you need as long as the suspension is homogeneous.
