DDP-38003 dihydrochloride, a tranylcypromine (TCPA) derivative, is a novel, potent and orally bioavailable inhibitor of histone lysine-specific demethylase 1A (KDM1A/LSD1). DDP-38003 inhibits KDM1A with an IC50 of 84 nM. DDP-38003 is more active in reducing the colony forming ability and in inducing thedifferentiation of THP-1 cells compared to the 1R, 2S analogue. It exhibited in vivo efficacy after oral administration, determining a 62% increased survival in mouse leukemia model with evidence of KDM1A inhibition. The biological profile of DDP-38003 supports its further investigation as a cancer therapeutic.

Biological Activity

ln Vitro	KDM1A is inhibited by DDP-38003 at an IC50 of 84 nM. Compared to the 1R, 2S counterpart, DDP-38003 is more effective in inhibiting the capacity of THP-1 cells to form colonies and at promoting their differentiation[1].
ln Vivo	Following oral dosing, DDP-38003 has in vivo efficacy as demonstrated by a 62% increase in survival in mouse leukemia models with evidence of KDM1A suppression. DDP-38003 has a half-life of eight hours. Treatment with DDP-38003 significantly increases the survival rate of mice in a dose-dependent manner. At doses of 11.25 and 22.50 mg/kg, respectively, the survival rate rises by 35% and 62%, respectively. One possible oral anticancer drug is DDP-38003[1].
Animal Protocol	Dissolved in 40% PEG 400 in a 5% glucose solution; 11.25 and 22.50 mg/kg; oral admin. Mouse leukemia models

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). Injection Formulation 4: DMSO : 20% SBE-β-CD in saline = 10 : 90 [i.e. 100 μL DMSO → 900 μL (20% SBE-β-CD in saline)] *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.

InvivoChem strongly recommends customers to read literature methods/protocols carefully before determining which formulation you should use for in vivo studies, as different compounds have different solubility properties and have to be formulated differently.  (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.
