Biological Activity

Description 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 cell testing, the water-soluble S7507 LDN-193189 2HCl is recommended.This product has poor solubility, animal experiments are available, cell experiments please choose carefully!

In vitro

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, this compound also shows the inhibitory effect on the transcriptional activity induced by either constitutively active ALK2R206H or ALK2Q207D mutant proteins. [1]

A recent study shows that this chemical blocks the production of reactive oxygen species induced by oxidized LDL during atherogenesis in human aortic endothelial cells. [4]
In vivo

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. [1]

This compound dorsalizes zebrafish embryos by inhibiting signaling pathways induced by bone morphogenetic protein (BMP)6 without effect on vascular development. [2]

In PCa-118b tumor-bearing mice, this chemical treatment attenuates tumor growth and reduces bone formation in the tumors. [3]

In LDL receptor-deficient (LDLR-/-) mice, this agent potently inhibits development of atheroma. Moreover, it also exhibits the inhibitory effects on associated vascular inflammation, osteogenic activity, and calcification. [4]

Protocol (from reference)

Kinase Assay:

[1]
  • Alkaline phosphatase activity

    C2C12 cells are seeded into 96-well plates at 2,000 cells per well in DMEM supplemented with 2% FBS. The wells are treated in quadruplicate with BMP ligands and LDN-193189 or vehicle. The cells are collected after 6 days in culture in 50 μL Tris-buffered saline and 1% Triton X-100. The lysates are added to p-nitro-phenylphosphate reagent in 96-well plates for 1 hours and then evaluated alkaline phosphatase activity (absorbance at 405 nm). Cell viability and quantity are measured by Cell Titer Aqueous One (absorbance at 490 nm), using replicate wells treated identically to those used for alkaline phosphatase measurements.

Customer Product Validation

<p>LDN induces signifiant cell death. OVCA429 cells were treated with vehicle (DMSO) or experimental drugs for 6 hr to capture different stages of cell death. OVCA429 cell viability was assessed in response to drug treatment for 6 hr by staining with AO (green) and EB (orange). For clarity the different fluorescent channels to detect AO, EB, and the over-lapping images are shown for 10 mM LDN treatment.</p>

The small molecule BMP inhibitor LDN-193189 can partially block the increased BMP signaling in Jab1flox/flox, Col2a1-Cre mutants in a dose-dependent manner. Primary chondrocytes were cultured in DMEM medium containing 10% FBS and indicated amounts of LDN-193189 for 24 hours before being subjected to immunoblotting.
