Methode voor het bereiden van in vivo formulering: Neem μL DMSO mastervloeistof, voeg vervolgens toe μL Maïsolie, mengen en helder maken.

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. Fysische methoden zoals vortexen, echografie of een warmwaterbad kunnen worden gebruikt om het oplossen te bevorderen.

Werkingsmechanisme (Mechanism of Action)

Targets/IC₅₀/Ki	JAK1 (Cell-free assay) 11 nM JAK2 (Cell-free assay) 18 nM JAK3 (Cell-free assay) 155 nM
In vitro	Momelotinib (CYT387) inhibits the proliferation of parental Ba/F3 cells (Ba/F3-wt) stimulated by IL-3 with IC50 of 1400 nM. Furthermore, it also causes the inhibition of cell proliferation in cell lines constitutively activated by JAK2 or MPL signaling, including Ba/F3-MPLW515L cells, CHRF-288-11 cells and Ba/F3-TEL-JAK2 cells with IC50 of 200 nM, 1 nM and 700 nM, respectively. In addition, this compound has been shown to inhibit erythroid colony growth in vitro from JAK2V617F-positive PV patients with similar potency with IC50 of 2μ-4 μM. A recent study shows that it inhibits PI3K/AKT and Ras/MAPK signaling induced by IL-6 and IGF-1. Moreover, it induces apoptosis as a single agent and synergizes with the conventional anti-MM therapies bortezomib and melphalan in primary multiple myeloma (MM) cells.
Kinase Assay	Cell-free kinase activity assays
Kinase Assay	In insectencellen tot expressie gebrachte Glutathione-S-transferase (GST)-getagde JAK-kinasedomeinen worden gezuiverd voor gebruik in een peptidesubstraat-fosforyleringstest met Momelotinib (CYT387). De testen worden uitgevoerd in 384-well optiplates met behulp van een Alphascreen Protein Tyrosine Kinase P100 detectiekit en een PerkinElmer Fusion Alpha-instrument.
In vivo	In a murine MPN model, Momelotinib (CYT387) normalizes white cell counts, hematocrit, spleen size, and restores physiologic levels of inflammatory cytokines.
