Biological Activity
| ln Vivo | MDSCs treated with ABR-238901 (30 mg/kg/day; gavage; for 3 weeks) exhibit decreased angiogenesis as well as IL6 and IL10 levels[1]. When paired with bortezomib (0.6 mg/kg; subcutaneous injection; twice weekly), ABR-238901 (30 mg/kg/day; gavage) decreased the amount of tumor when compared to therapy with either drug alone[1]. In C57BL/6NRJ mice, ABR-238901 (30 mg/kg; intraperitoneal; for the first three days; then, continuing oral daily dosage; for 21 days) causes myocardial ischemia brought on by permanent coronary artery ligation, which progressively deteriorates cardiac function and speeds up left ventricular remodeling. In the initial three days following a myocardial infarction (MI), ABR-238901 treatment reduces inflammatory damage and fosters a healing milieu[2]. |
| Animal Protocol |
Animal/Disease Models: C57BL/KaLwRij mice with 5T33MMvv cells[1] Doses: 30 mg/kg Route of Administration: Gavage; daily; for 3 weeks Experimental Results: Caused less angiogenesis. Caused less IL6 and IL10 in myeloid-derived suppressor cells (MDSCs). |

Solubility Data
| Solubility (In Vitro) |
DMSO: 33.33 mg/mL (84.46 mM) H2O: < 0.1 mg/mL |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.34 mM) (saturation unknown) in 10% DMSO + 40% PEG300 +5% Tween-80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 + to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution.  (Please use freshly prepared in vivo formulations for optimal results.) |
