Stap 1: Voer onderstaande informatie in (Aanbevolen: een extra dier om rekening te houden met verlies tijdens het experiment)
Stap 2: Voer de in vivo formulering in (Dit is alleen de calculator, geen formulering. Neem eerst contact met ons op als er geen in vivo formulering is in de sectie oplosbaarheid.)
Berekeningsresultaten:
Werkconcentratie: mg/ml;
Methode voor het bereiden van DMSO-moedervloeistof: mg geneesmiddel vooropgelost in μL DMSO ( Concentratie moedervloeistof mg/mL, Neem eerst contact met ons op als de concentratie de DMSO-oplosbaarheid van de batch van het geneesmiddel overschrijdt. )
Methode voor het bereiden van in vivo formulering: Neem μL DMSO moedervloeistof, voeg daarna toeμL PEG300, mengen en verhelderen, daarna toevoegenμL Tween 80, mengen en verhelderen, daarna toevoegen μL ddH2O, mengen en verhelderen.
Methode voor het bereiden van in vivo formulering: Neem μL DMSO moedervloeistof, voeg daarna toe μL Maïsolie, mengen en verhelderen.
Opmerking: 1. Zorg ervoor dat de vloeistof helder is voordat u het volgende oplosmiddel toevoegt.
2. Zorg ervoor dat u het/de oplosmiddel(en) in de juiste volgorde toevoegt. U moet ervoor zorgen dat de verkregen oplossing, bij de vorige toevoeging, een heldere oplossing is voordat u verdergaat met het toevoegen van het volgende oplosmiddel. Fysieke methoden zoals vortexen, ultrasoon of een warmwaterbad kunnen worden gebruikt om het oplossen te bevorderen.

PARP1
(Cell-free assay) 0.57 nM

| In vitro |
BMN-673 bindt selectief aan PARP en voorkomt PARP-gemedieerde DNA-reparatie van enkelstrengs DNA-breuken via de base-excision repair pathway. Dit versterkt de accumulatie van DNA-strengbreuken, bevordert genomische instabiliteit en leidt uiteindelijk tot apoptose. BMN 673 doodt selectief kankercellen met BRCA-1- of BRCA-2-mutaties. BMN 673 vertoont cytotoxiciteit als enkelvoudig middel in BRCA-1-mutante (MX-1, IC50 = 0,3 nM) en BRCA-2-mutante cellen (Capan-1, IC50 = 5 nM). Daarentegen varieert de IC50 van BMN 673 in MRC-5 normale menselijke fibroblasten en andere tumorcellijnen met wildtype BRCA-1- en BRCA-2-genen tussen 90 nM en 1,9 μM. Off-target moleculaire screening identificeerde geen significante niet-specifieke activiteit voor deze klasse van PARP-remmers. |
| In vivo |
In farmacokinetische studies bij ratten vertoont BMN-673 (Talazoparib) een orale biologische beschikbaarheid van >50% en farmacokinetische eigenschappen die een eenmaal daagse dosering mogelijk maken. In studies met het MX-1 xenograft tumormodel verbetert dagelijkse orale dosering van BMN-673 (Talazoparib) de antitumorale effecten van cytotoxische therapieën significant op een dosisafhankelijke manier. |

Vraag 1:
Which solvent do you recommend to dilute it for in vivo study in mice?
Antwoord:
According to the paper: http://clincancerres.aacrjournals.org/content/19/18/5003.full, it can be dissolved in vehicle (10% DMAc, 6% Solutol, and 84% PBS). Quote from Method and Material section "Xenograft experiments: BMN 673 (various doses as indicated), or vehicle (10% DMAc, 6% Solutol, and 84% PBS) was administered by oral gavage"
