Fosdagrocorat (formerly known as PF-04171327) is a phosphate ester prodrug of PF-00251802 (dagrocorat), a selective high-affinity partial agonist of the glucocorticoid receptor, which is further metabolized to PF-04015475. Dagrocorat (also known as PF-00251802) is a novel and potent dissociated glucocorticoid receptor agonist with the potential usefulness as an anti-inflammatory agent. The dissociated agonists of the glucocorticoid receptor are a novel class of agents in clinical development for rheumatoid arthritis. PF-00251802 is a reversible inhibitor of several CYPs, but modeling has suggested no clinically relevant interaction. PF-00251802 and PF-04015475 are time-dependent inhibitors and inducers of CYP3A in vitro; PF-00251802 is also a time-dependent inhibitor of CYP2D6. Model-based prediction suggested the potential for weak inhibition of CYP3A in vivo. A clinical DDI study was conducted with midazolam, a sensitive CYP3A substrate. A phase 1 open-label, multiple-dose study evaluated the effect of PF-04171327 on midazolam pharmacokinetics and safety in 12 healthy volunteers. Administration of midazolam alone or concomitantly with PF-04171327 resulted in equivalent pharmacokinetic profiles (AUCinf , 21.17 vs 20.28 ng·h/mL, respectively), indicating that PF-04171327 had no net effect on CYP3A activity in vivo. These findings support the further development of PF-00251802 and PF-04171327 as potential treatments for patients with rheumatoid arthritis (NCT00987038).

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (3.62 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 (3.62 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.) |

| 10 mM | 0.1741 mL | 0.8703 mL | 1.7406 mL |
*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
Calculation results
Working concentration： mg/mL；
Method for preparing DMSO stock solution： mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.
