Acebilustat, also known as ZK322, is a novel, oral, potent and selective leukotriene A4 hydrolase inhibitor that is a promising new once-daily oral antiinflammatory drug in development for treatment of cystic fibrosis (CF) and other diseases. In a Phase I study, seventeen patients with mild to moderate cystic fibrosis were enrolled and randomized into groups receiving placebo or doses of 50 mg or 100 mg acebilustat administered orally, once daily for 15 days. Sputum neutrophil counts were reduced by 65% over baseline values in patients treated with 100 mg acebilustat. A modestly significant 58% reduction vs. placebo in sputum elastase was observed with acebilustat treatment. Favorable trends were observed for reduction of serum C-reactive protein and sputum neutrophil DNA in acebilustat-treated patients. No changes in pulmonary function were observed. Acebilustat was safe and well tolerated. The results of this study support further clinical development of acebilustat for treatment of cystic fibrosis.
| ln Vitro |
Leukotriene A4 hydrolase inhibitor acebilustat (CTX-4430) has been shown in phase 1 trials to be safe and well tolerated[1]. An anti-inflammatory medication called acebilustat is being developed to treat CF and other conditions. It is a potent inhibitor of the enzyme leukotriene A4 hydrolase (LTA4H), which catalyzes the rate-limiting step in the formation of leukotriene B4 (LTB4), a potent chemoattractant and activator of inflammatory immune cells including neutrophils[2].

| Additional Infomation |
Acebilustat is under investigation in clinical trial NCT01748838 (Phase 1 Study Assessing the Safety and Tolerability of CTX-4430).
Acebilustat is an orally bioavailable, small molecule inhibitor of the enzyme leukotriene A4 hydrolase (LTA4H), with potential anti-inflammatory activity. Upon oral administration, acebilustat targets and inhibits the activity of LTA4H, thereby inhibiting the synthesis of the pro-inflammatory mediator leukotriene B4 (LTB4). This may reduce inflammation in various inflammatory disorders including cystic fibrosis and serious pulmonary inflammatory diseases. LTA4H catalyzes a major and rate-limiting step in LTB4 production, and LTB4 plays an important role in pulmonary and systemic inflammation. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 1.67 mg/mL (3.47 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 16.7 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: ≥ 1.67 mg/mL (3.47 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 16.7 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. View More

*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.
