Biological Activity
| ln Vitro | ALDH1A1, hALDH1A3, and hALDH2 are all inhibited by NCT-506, with IC50 values of 0.007±0.001, 16.4±3.99, and 21.5 μM, respectively[1]. With an EC50 of 45.6 μM, NCT-506 (100, 10, 1, 0.1 μM, 6 days) dramatically decreased cell viability in OV-90 cells. NCT-506 inhibited MIA PaCa-2, OV-90, and HT-29 cells with IC50 values of 0.077±0.040, 0.161±0.038, and 0.048±0.022 μM, respectively, in experiments using aldeflu cells [1]. The IC50 values for NCT-506 in combination with paclitaxel were 1202, 924, 870, 411, 102, and 31.8 nM, respectively, at SKOV-506 doses of 0 (DMSO), 1, 3, 10, 20, and 30 μM. correspondingly, 3 TR cells[1]. |
| Cell Assay |
Cell viability assay [1] Cell Types: OV-90 and SKOV-3-TR Cell Tested Concentrations: 100, 10, 1, 0.1 μM Incubation Duration: 6 days for OV-90 cells; 4 days for SKOV-3-TR cells Experimental Results: OV Cell viability was Dramatically diminished in -90 cells, with an EC50 of 45.6 μM. Combination treatment (paclitaxel concentration of 100 nM) diminished cell viability in SKOV-3-TR cells with an EC50 of 11.2 μM. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~33.33 mg/mL (~69.65 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (5.22 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 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. Solubility in Formulation 2: ≥ 2.5 mg/mL (5.22 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 25.0 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.) |
