CAS No. 1062368-24-4
LDN-193189 (DM3189) is a selective BMP signaling inhibitor, inhibits the ALK1, ALK2, ALK3 and ALK6 with IC50s of 0.8 nM, 0.8 nM, 5.3 nM and 16.7 nM in the kinase assay, respectively. LDN-193189 inhibits the transcriptional activity of the BMP type I receptors ALK2 and ALK3 with IC50s of 5 nM and 30 nM in C2C12 cells, respectively, exhibits 200-fold selectivity for BMP versus TGF-β. For animal testing, the water-soluble S7507 LDN-193189 2HCl is recommended.

LDN193189 potently inhibits BMP4-mediated Smad1, Smad5 and Smad8 activation with IC50 of 5 nM, and efficiently inhibits transcriptional activity of the BMP type I receptors ALK2 and ALK3 with IC50 of 5 nM and 30 nM, respectively. Furthermore, LDN193189 also shows the inhibitory effect on the transcriptional activity induced by either constitutively active ALK2R206H or ALK2Q207D mutant proteins.  A recent study shows that LDN-193189 blocks the production of reactive oxygen species induced by oxidized LDL during atherogenesis in human aortic endothelial cells. 
In conditional caALK2-transgenic mice with Ad.Cre on on postnatal day 7 (P7), LDN-193189 (3 mg/kg i.p) leads to mild calcifications surrounding the left tibia and fibula first visible at P13, and prevents radiographic lesions at P15 without causing weight loss or growth retardation, spontaneous fractures, decreased bone density or behavioral abnormalities.  LDN193189 dorsalizes zebrafish embryos by inhibiting signaling pathways induced by bone morphogenetic protein (BMP)6 without effect on vascular development.  In PCa-118b tumor-bearing mice, LDN-193189 treatment attenuates tumor growth and reduces bone formation in the tumors.  In LDL receptor-deficient (LDLR-/-) mice, LDN-193189 potently inhibits development of atheroma. Moreover, LDN-193189 also exhibits the inhibitory effects on associated vascular inflammation, osteogenic activity, and calcification.

1.Please make sure the liquid is clear before adding the next solvent.
2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (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.
