CB-1158 dihydrochloride (INCB01158 dihydrochloride) is a potent and orally active inhibitor of arginase, with IC50s of 86 nM and 296 nM for recombinant human arginase 1 and recombinant human arginase 2, respectively. Immuno-oncology agent[1].
CB-1158 dihydrochloride is a potent and orally-bioavailable inhibitor of arginase, with IC50s of 86 and 296 nM for recombinant human arginase 1 and 2, respectively. CB-1158 inhibits native rginase 1 (Arg1) in human granulocyte, erythrocyte, and hepatocyte lysate with IC50s of 178 nM, 116 nM and 158 nM, respectively, and blocks Arg1 in cancer patient plasma (IC50, 122 nM). CB-1158 also exhibits potent inhibitory activity against arginase in human HepG2, K562 cell lines and primary human hepatocytes with IC50s of 32, 139, 210 μM, respectively. CB-1158 shows no effect on NOS. In addition, CB-1158 is not directly cytotoxic to murine cancer cell lines[1].
CB-1158 (100 mg/kg, p.o., twice per day) increases the number of tumor-infiltrating cytotoxic cells and decreases myeloid cells in mice. CB-1158 in combination with PD-L1 blockade or LY 188011 inhibits tumor growth in mice bearing CT26 cancer cells[1].

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Working concentration: mg/ml;
Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
