Ilorasertib (also known as ABT-348) is a potent, novel, orally bioavailable and ATP-competitive multi-kinase inhibitor with IC50s for inhibiting binding Aurora B (7 nM), C (1 nM), and A (120 nM), and also inhibits RET tyrosine kinase, PDGFRβ, and Flt1 with IC50s of 7 nM, 3 nM and 32 nM. ABT 348 was assessed and found to be efficacious in representative solid tumor (HT1080 and MiaPaCa, tumor stasis) and hematological malignancy (RS4;11, regression) xenografts due to its distinct spectrum of activity. The rationale behind evaluating ABT-348 clinically as a therapeutic agent for cancer treatment is provided by these findings.

| Additional Infomation |
Ilorasertib has been used in trials studying the treatment of Myelodysplasia, Solid Neoplasm, Advanced Cancers, Advanced Solid Tumors, and Acute Myelogenous Leukemia, among others.
Ilorasertib is an orally bioavailable, adenosine triphospate mimetic, and inhibitor of Aurora kinases, vascular endothelial growth factor receptors (VEGFRs) and platelet-derived growth factor receptor (PDGFRs), with potential antineoplastic activity. Upon administration, ilorasertib selectively binds to and inhibits Aurora kinases A, B and C, which may disrupt both the assembly of the mitotic spindle apparatus and chromosome segregation, and inhibit both cellular division and proliferation in Aurora kinase-overexpressing tumor cells. In addition, ilorasertib selectively binds to and inhibits VEGFRs and PDGFRs, which may result in the inhibition of both angiogenesis and tumor cell proliferation in VEGFR/PDGFR-overexpressing tumor cells. This agent also inhibits the Src family of cytoplasmic tyrosine kinases. Aurora kinases A, B and C, are serine/threonine kinases that play essential roles in mitotic checkpoint control and are overexpressed by a wide variety of tumor cell types. Both VEGFRs and PDGFRs are receptor tyrosine kinase families whose members may be upregulated in various tumor cell types. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.08 mg/mL (4.26 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 (4.26 mM) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. 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 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. (Please use freshly prepared in vivo formulations for optimal results.) |

*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.
