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.

Meccanismo d'azione (Mechanism of Action)

Caratteristiche	Most potent and selective PARPi reported thus far.
Targets/IC₅₀/Ki	PARP1 (Cell-free assay) 0.57 nM
In vitro	BMN-673 selectively binds to PARP and prevents PARP-mediated DNA repair of single strand DNA breaks via the base-excision repair pathway. This enhances the accumulation of DNA strand breaks, promotes genomic instability and eventually leads to apoptosis. BMN 673 selectively kills cancer cells with BRCA-1 or BRCA-2 mutations. BMN 673 demonstrates single-agent cytotoxicityin BRCA-1 mutant (MX-1, IC50 = 0.3 nM) and BRCA-2 mutant cells (Capan-1, IC50 = 5 nM). In contrast, in MRC-5 normal human fibroblastand other tumor cell lines with wild-type BRCA-1 and BRCA-2 genes, IC50 of BMN 673 ranges between 90 nM and 1.9 μM. Off-target molecular screening did not identify significant non-specific activity for this class of PARP inhibitors.
In vivo	In rat pharmacokinetic studies, BMN 673 displays >50% oralbioavailability and pharmacokinetic properties that enable singledaily dosing. In MX-1 xenograft tumor model studies, daily oral dosingof BMN 673 significantly enhances the antitumor effects ofcytotoxic therapies in a dose-dependent manner.
