Napabucasin, panobinostat, and quisinostat were purchased from Selleckchem and A1331852 and Navitoclax from Chemietek, diluted in DMSO to make stock solutions, aliquoted and stored at −80C. Napabucasin was formulated by heating to 50C for 10 minutes and then sequentially adding 45% PEG300 (Sigma), 5% Tween80 (Sigma) and 45% sterile water, with vortexing after adding each component (Selleckchem). panobinostat was formulated by sequentially adding 48% PEG300 (Sigma), 2% Tween80 (Sigma) and 48% sterile water, with vortexing after adding each component (Selleckchem). quisinostat was formulated in 10% hydroxypropyl-b-cyclodextrin (Sigma), 25 mg/ml mannitol (Sigma), in sterile water(45 (link)). A1331852 was formulated by sequentially adding 10% Ethanol (Fisher), 60% Phosal 50 PG (Lipoid), and 30% PEG400 (Sigma), and vortexing (MedChemExpress). Navitoclax was formulated in 10% ethanol (Fisher), 30% PEG400 (Sigma), and 60% Phosal 50 PG (Lipoid), with vortexing after adding each component (MedChemExpress). Sorafenib was formulated in 90% corn oil (Selleckchem) with vortexing (MedChemExpress). Working solutions were made fresh prior to administration.
