Product Description

LDN-193189 (also called LDN193189; DM-3189; DM3189) is a highly potent and selective small molecule inhibitor of the BMP (bone morphogenetic protein) signaling pathway with potential antineoplastic activity. It inhibits the transcriptional activity of the BMP type I receptor kinases such as ALK2 (activin receptor-like kinase-2) and ALK3 with IC50s of 5 nM and 30 nM in C2C12 cells, respectively. LDN-193189 exhibits 200-fold selectivity for BMP over TGF-β. LDN-193189 also exhibits the inhibitory effects on associated vascular inflammation, osteogenic activity, and calcification.

Biological Activity I Assay Protocols (From Reference)
ln Vitro
Human pluripotent stem cells (hPSCs) are stimulated by LDN193189 (GMP) (250 nM; 0-7 d) to develop directly into midbrain dopamine neurons (mDA)[1]. In vitro, hPSCs are induced to produce glucose-responsive β cells by LDN193189 (GMP) at a concentration of 200 nM[2].
ln Vivo
LDN-193189 (ip; 3 mg/kg; daily; 35 days) may have an impact on how breast cancer cells interact with their surroundings in the bone[3]. LDN-193189 (ip; 3 mg/kg; single) reduces functional impairment and ectopic ossification [1].
Animal Protocol
Animal/Disease Models: Ahymic NMRI nude female mice (6weeks old)[3]
Doses: 3 mg/kg
Route of Administration: Itraperitoneal, daily, for 35 days
Experimental Results: Ehanced etastases development in vivo.

Animal/Disease Models: C57BL/6 mice[1]
Doses: 3 mg/kg
Route of Administration: Intraperitoneal, single
Experimental Results: Diminished ectopic bone formation and preserved joint spaces over the same interval without inducing fractures, osteopenia or skeletal abnormalities.

*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
g/mol

Molecular Weight Calculator allows you to calculate the molar mass and elemental composition of a compound, as detailed below:

Note: Chemical formula is case sensitive: C12H18N3O4  c12h18n3o4
Instructions to calculate molar mass (molecular weight) of a chemical compound:
  • To calculate molar mass of a chemical compound, please enter the chemical/molecular formula and click the “Calculate’ button.
Definitions of molecular mass, molecular weight, molar mass and molar weight:
  • Molecular mass (or molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
  • Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.

Reconstitution Calculator allows you to calculate the volume of solvent required to reconstitute your vial.

  • Enter the mass of the reagent and the desired reconstitution concentration as well as the correct units
  • Click the “Calculate” button
  • The answer appears in the Volume (to add to vial) box
In vivo Formulation Calculator (Clear solution)
Step 1: Enter information below (Recommended: An additional animal to make allowance for loss during the experiment)
Step 2: Enter in vivo formulation (This is only a calculator, not the exact formulation for a specific product. Please contact us first if there is no in vivo formulation in the solubility section.)

Calculation results

Working concentration mg/mL;

Method for preparing DMSO stock solution mg drug pre-dissolved in μL DMSO (stock solution concentration mg/mL). Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug.

Method for preparing in vivo formulation:Take μL DMSO stock solution, next add μL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O,mix and clarify.

(1) Please be sure that the solution is clear before the addition of next solvent. Dissolution methods like vortex, ultrasound or warming and heat may be used to aid dissolving.
             (2) Be sure to add the solvent(s) in order.
