Ladarixin sodium (DF 2156A), an investigational small-molecule drug, is a potent, orally bioavailable, non-competitive, dual allosteric inhibitor of CXCR1 and CXCR2 interleukin-8 (IL-8A and IL-8B, respectively). In preclinical studies, ladarixin was shown to prevent and reverse diabetes in NOD mice. The potency of CXCR1/2 inhibition may prevent inflammation- and autoimmunity-mediated damage of pancreatic islets. CXCR1/2 inhibition blocks and reverses type 1 diabetes in mice.
| ln Vitro |
Human polymorphonuclear leukocytes (PMN) are inhibited in their migration to CXCL8 (IC50 0.7 nM) by ladararixin [2].

| ln Vivo |
In a single OVA exposure scenario, ladararixin (10 mg/kg; oral, once daily) decreases allergic airway inflammation. In a chronic OVA exposure model, ladararixin decreases bronchial hyperresponsiveness, remodeling, and allergic airway inflammation [1]. Ladararixin (10 mg/kg; orally, once day for 8 days) decreases the fibrosis and inflammation of the lungs caused by bleomycin in mice [1]. Ladararixin (10 mg/kg; once daily, oral) prevents mice's influenza A infection from getting worse when exposed to cigarette smoke [1]. Additionally, ladararixin successfully lowers polymorphonuclear leukocyte infiltration generated by CXCL8 in a number of animal models without significantly lowering systemic neutrophil numbers in a dose-related manner [2].

| Animal Protocol |
Animal/Disease Models: Mouse (cigarette smoke induced exacerbation model of influenza A infection) [1]
Doses: 10 mg/kg Route of Administration: Oral one time/day on days 2, 3 and 4 after infection Experimental Results: Dramatically attenuated exacerbation of lethality and respiratory changes noted in the CSFlu group. |

| Additional Infomation |
Ladarexin sodium is the sodium salt form of lardaraxine, a small-molecule dual inhibitor with high oral bioavailability that inhibits CXC motif chemokine receptors 1 (CXCR1) and 2 (CXCR2), exhibiting potential anti-inflammatory and antitumor activities. After oral administration, lardaraxine selectively targets and allosterically binds to CXCR1 and CXCR2, thereby preventing their activation by their ligands and the pro-inflammatory chemokine interleukin-8 (IL-8 or CXCL8). This inhibits CXCR1/2-mediated signaling, thereby suppressing the inflammatory process, reducing the recruitment and migration of immunosuppressive myeloid-derived suppressor cells (MDSCs) and neutrophils in the tumor microenvironment (TME), and eliminating the immunosuppressive properties of the TME. This enables effector cells, such as natural killer (NK) cells and cytotoxic T lymphocytes (CTLs), to kill and eliminate cancer cells and inhibit tumor cell migration, metastasis, angiogenesis, and proliferation. CXCR1 and CXCR2 are G protein-coupled receptors located on myeloid cells and certain tumor cells, playing crucial roles in the immunosuppressive properties of the tumor microenvironment (TME), tumor metastasis, chemotherapy resistance, and myeloid cell suppression. They also play a key role in inflammation and are elevated in a variety of inflammatory diseases.

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.29 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 25.0 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: ≥ 2.5 mg/mL (6.29 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. 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.
