Gilteritinib-d8 is the octa-deuterated form of Gilteritinib (ASP-2215), which is a potent and ATP-competitive FLT3/AXL inhibitor with IC50s of 0.29 nM/0.73 nM, respectively. Gilteritinib (Xospata) has been approved for treating acute myeloid leukemia (AML). It inhibits FLT3 and AXL with IC50 values of 0.29 nM and 0.73 nM, respectively. Gilteritinib potently inhibits FLT3 with an IC50 that is about 800-fold higher than the concentration required to inhibit c-KIT (230 nM). Gilteritinib has the potential to treat leukemia such as AML with either or both FLT3-ITD and FLT3-D835 mutations. In vitro, among the 78 tyrosine kinases tested, Gilteritinib at 1 nM concentration inhibits FLT3, leukocyte tyrosine kinase (LTK), anaplastic lymphoma kinase (ALK), and AXL kinases by over 50% with an IC50 value of 0.29 nM for FLT3, and is approximately 800-fold more potent than for c-KIT. As of November 2018, Gilteritinib was approved by US FDA to treat patients who have relapsed or refractory acute myeloid leukemia (AML).

Biological Activity
| ln Vitro | Drug compounds have included stable heavy isotopes of carbon, hydrogen, and other elements, mostly as quantitative tracers while the drugs were being developed. Because deuteration may have an effect on a drug's pharmacokinetics and metabolic properties, it is a cause for concern [1]. |

Solubility Data
| Solubility (In Vitro) | May dissolve in DMSO (in most cases), if not, try other solvents such as H2O, Ethanol, or DMF with a minute amount of products to avoid loss of samples |
| Solubility (In Vivo) |
Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples. Injection Formulations (e.g. IP/IV/IM/SC) Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
