JNJ-42041935 was the most potent inhibitor of PHD2181–417 with a pIC50 value of 7.0 ± 0.03. JNJ-42041935 caused a concentration-dependent elevation of cellular HIF-1α and erythropoietin release in Hep3B cells. JNJ-42041935 (100 μmol/kg, once a day for 14 days) was effective in reversing inflammation-induced anemia.

| Preparation method | The potency of compounds for stabilization of intracellular HIF-1α and release of erythropoietin into the media was assessed in the human hepatoma cell line Hep3B. Cells were cultured in Dulbecco's modified Eagle's medium/high glucose (Invitrogen) supplemented with 10% fetal calf serum and 2 mM l-glutamine, 1% nonessential amino acids, 1 mM sodium pyruvate, 50 IU/ml penicillin, and 50 μg/ml streptomycin. A range of concentrations was incubated in 96-well plates with 30,000 cells/well for 24 h. Incubation media were collected, and cells were subsequently lysed for assessment of cellular HIF-1α content and erythropoietin concentration. |

| Km factor | 3 | 6 | 12 | 8 | 5 | 20 |
| Animal A (mg/kg) = Animal B (mg/kg) multiplied by | Animal B Km |
| Animal A Km |
For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
