Biological Activity
| ln Vitro | DMT1 blocker 2 (Compound 12f) does not cause any harm to HepG2 cells at 10 μM after 24 hours [1]. CYP3A4 activity is 44% inhibited by DMT1 blocker 2 (10 μM) [1]. |
| ln Vivo | In an acute model of iron hyperabsorption, DMT1 blocker 2 (50 mg/kg; oral) inhibits the response of intestinal cells to iron-containing foods [1]. |
| Animal Protocol |
Animal/Disease Models: Weanling (3-4 weeks) rats were placed on a low-iron diet for four weeks [1] Doses: 50 mg/kg Route of Administration: po (oral gavage), followed by iron challenge 1 hour later Experimental Results: Attenuated post-challenge serum iron increase. |

Solubility Data
| Solubility (In Vitro) | DMSO : ~50 mg/mL (~189.90 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (9.50 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in 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 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (9.50 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.) |
