AZD5423 is the first clinical candidate that displayed a potent inhibition of lung edema in a rat model of allergic airway inflammation following dry powder inhalation combined with a moderate systemic GR-effect, assessed as thymic involution. Further optimization of inhaled drug properties provided a second, equally potent, candidate, AZD7594 (also known as AZ13189620), which is a novel, potent selective nonsteroidal indazole ether-based glucocorticoid receptor modulators (SGRMs) with an IC50 of 0.9 nM. AZD-7594 is an inhaled selective glucocorticoid receptor (GCCR) modulator for the inhaled treatment of respiratory diseases. AZD7594 demonstrated an improved therapeutic ratio over the benchmark inhaled corticosteroid 3 (fluticasone propionate) and prolonged the inhibition of lung edema, indicating potential for once-daily treatment. AZD-7594 is currently in phase II clinical trials by AstraZeneca for the treatment of mild to moderate asthma. It is also in phase I clinical trials for the treatment of chronic obstructive pulmonary disorder (COPD).

Solubility Data
| Solubility (In Vitro) | DMSO : ~100 mg/mL (~205.15 mM) |
| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.27 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 (4.27 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.) |
