ASLAN003 is a novel, potent and orally bioavailable inhibitor of DHODH (Human Dihydroorotate Dehydrogenase) which has the potential to be first-in-class in AML (Acute Myelogenous Leukemia). ASLAN003 has antitumor activity.
| ln Vitro |
For 48 hours, farudodstat (0.01-100 μM) suppresses the growth of leukemia cells. 50% or more of the cell viability is maintained at concentrations of Farudodstat [1]. Cleaved caspase 8 is considerably increased by farudodstat (0.5, 1 μM) for 48 hours [1]. Farudodstat (2, 4 μM; for 96 hours) decreases viability and causes differentiation in myelodysplastic syndrome samples and primary acute myeloid leukemia blasts [1]. It was demonstrated that in MOLM-14 and KG-1 cells, fardodstat (1, 2 μM; 1 hour pretreatment before OPP, 1 hour on) slows protein synthesis and decreases incorporation of O-propargylpuromycin (OPP) into protein translation sites. RPL6 and EIF4B protein downregulation is brought on by farudodstat [1].

The number of disseminated tumors is significantly decreased and survival is prolonged when farudstat (50 mg/kg; oral gavage; once daily; days 3 to 30) is administered [1].

| Additional Infomation |
Farudodstat (ASLAN003) is under investigation in clinical trial NCT03451084 (A Dose Optimisation Study of ASLAN003 in Acute Myeloid Leukemia).
Farudodstat is an orally available inhibitor of dihydroorotate dehydrogenase (DHODH), with potential antineoplastic activity. Upon administration, farudodstat specifically targets, binds to and prevents the activation of DHODH, thereby preventing the fourth enzymatic step in de novo pyrimidine synthesis. This prevents uridine monophosphate (UMP) formation, DNA synthesis, cell division and cellular proliferation, causes reactive oxygen species (ROS) formation, enables differentiation and induces apoptosis in susceptible tumor cells. DHODH, a mitochondrial enzyme, catalyzes the conversion of dihydroorotate (DHO) to orotate in the endogenous synthesis of UMP. |

| Solubility (In Vitro) |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.17 mg/mL (6.09 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 21.7 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: ≥ 2.17 mg/mL (6.09 mM) (saturation unknown) in 10% DMSO + 90% Corn Oil (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 21.7 mg/mL clear DMSO stock solution to 900 μL of corn oil and mix evenly. (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.
