Product Description
UNC569 is a novel, potent and selective small-molecule MER inhibitor with efficacy against acute lymphoblastic leukemia in vitro and in vivo. UNC569 inhibited downstream signaling via ERK1/2 and AKT as well as Mer activation. Under UNC569 treatment, there was a decrease in colony formation on methylcellulose/soft agar, a reduction in proliferation and survival in liquid culture, and an increase in sensitivity to cytotoxic chemotherapy. Cell lines and patient samples from ALL exhibit ectopically expressed Mer receptor tyrosine kinase.
Biological Activity I Assay Protocols (From Reference)
Targets
Mer (IC50 = 2.9 nM); Axl (IC50 = 37 nM); Tyro3 (IC50 = 48 nM); Mer (Ki = 4.3 nM)
ln Vitro
In all cell lines, UNC569 (24 hours) elevated short-term PARP[2] and Caspase 3 levels as well as cellular fluorescence. Potent suppression of activated Mer and downstream signaling, including PI3K, is processed by UNC569 (1 μM; 1.5 hr). In human B-ALL (acute lymphoblastic leukemia) 697 and Jurkat cell lines, UNC569 (1 hr) inhibits Mer phosphorylation levels with IC50 values of 141 nM and 193 nM [1].
ln Vivo
The pharmacokinetic characteristics of UNC569 (3 mg/kg) in vivo were assessed via in vitro (IV) and intravenous (PO) methods. Low systemic clearance (19.5 mL/min/kg), good wound bioavailability (57%) and high vial distribution (Vss of 5.83 L/kg) are characteristics of UNC569 [1]. For two weeks, bleached zebrafish were immersed in 4 μM UNC569. Comparing UNC569 to vehicle- and mock-treated fish, the results demonstrated a more than 50% reduction in tumor burden [2].

Shipping Condition
Room temperature (This product is stable at ambient temperature for a few days during ordinary shipping and time spent in Customs)
Solubility Data
Solubility (In Vitro)
DMSO: ~31.3 mg/mL (~78.8 mM)
Solubility (In Vivo)
Solubility in Formulation 1: ≥ 2.5 mg/mL (6.31 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.

 (Please use freshly prepared in vivo formulations for optimal results.)
Preparing Stock Solutions 1 mg 5 mg 10 mg
1 mM 2.5221 mL 12.6103 mL 25.2207 mL
5 mM 0.5044 mL 2.5221 mL 5.0441 mL
10 mM 0.2522 mL 1.2610 mL 2.5221 mL

*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.

Calculator

Molarity Calculator allows you to calculate the mass, volume, and/or concentration required for a solution, as detailed below:

  • Calculate the Mass of a compound required to prepare a solution of known volume and concentration
  • Calculate the Volume of solution required to dissolve a compound of known mass to a desired concentration
  • Calculate the Concentration of a solution resulting from a known mass of compound in a specific volume
An example of molarity calculation using the molarity calculator is shown below:
What is the mass of compound required to make a 10 mM stock solution in 5 ml of DMSO given that the molecular weight of the compound is 350.26 g/mol?
  • Enter 350.26 in the Molecular Weight (MW) box
  • Enter 10 in the Concentration box and choose the correct unit (mM)
  • Enter 5 in the Volume box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 17.513 mg appears in the Mass box. In a similar way, you may calculate the volume and concentration.

Dilution Calculator allows you to calculate how to dilute a stock solution of known concentrations. For example, you may Enter C1, C2 & V2 to calculate V1, as detailed below:

What volume of a given 10 mM stock solution is required to make 25 ml of a 25 μM solution?
Using the equation C1V1 = C2V2, where C1=10 mM, C2=25 μM, V2=25 ml and V1 is the unknown:
  • Enter 10 into the Concentration (Start) box and choose the correct unit (mM)
  • Enter 25 into the Concentration (End) box and select the correct unit (mM)
  • Enter 25 into the Volume (End) box and choose the correct unit (mL)
  • Click the “Calculate” button
  • The answer of 62.5 μL (0.1 ml) appears in the Volume (Start) box
