INO-1001 (also known as INO1001; INO 1001) is a novel isoindolinone based compound which acts as a potent inhibitor of the nuclear enzyme poly (ADP-ribose) polymerase (PARP) with chemosensitization and radiosensitization properties. INO-1001 inhibits PARP, which may result in inhibition of tumor cell DNA repair mechanisms and, so, tumor cell resistance to chemotherapy and radiation therapy. PARP enzymes are activated by DNA breaks and have been implicated in the repair of DNA single-strand breaks (SSB). as of 7/29/2016, many vendors are selling INO-1001 with wrong structure (3-aminobenzamide, CAS# 3544-24-9)

Solubility Data
| Solubility (In Vitro) | DMSO : ~31.25 mg/mL (~71.10 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.73 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 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 20.8 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. Solubility in Formulation 2: ≥ 2.08 mg/mL (4.73 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 20.8 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly.  (Please use freshly prepared in vivo formulations for optimal results.) |
