Background

LDN193189 is a selective transcriptional activity morphogenetic protein (BMP) type I receptors inhibitor. It inhibits activin receptor-like kinase-2 (ALK2) and ALK3 with IC50 values of 5 nM and 30 nM, respectively [1].

LDN193189 has been showed to inhibit BMP induced phosphorylation of Smad signaling (Smad1/5/8) and non-Smad signaling including p38 and Akt in C2C12 cells [2].

Pharmacological inhibition of BMP by LDN193189 has shown to prevent down-regulation of E-cadherin in response to BMP2 both in bronchial epithelial (Beas2B) cells and in C57BL/6 mice. LDN193189 also inhibits the BMP-induced reduction of epithelial permeability at cellular level [3].

General tips	We do not recommend long-term storage for the solution, please use it up soon.

Protocol

Cell experiment [1]:
Cell lines	C2C12 myofibroblast cells; bronchial epithelial (Beas2B) cells
Preparation method	This compound is limited soluble in DMSO. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.
Reacting condition	0.005-5 μM. 30-60 min
Applications	LDN-193189 inhibited both BMP induced Smad1/5/8 phosphorylation and BMP-mediated induction of the p38 MAPK, Erk1/2 and Akt pathway in C2C12 cells. LDN-193189 dose-dependently inhibited the activation of Smad1/5/8, p38 and Akt. LDN-193189 induced a strong increase in phosphorylated p38 MAPK levels and a slight increase in p-Akt in C2C12 cells. LDN (10 μM, 60 min) induced p38 and Akt phosphorylation. LDN (0.5 μM, 30 min) inhibited BMP-mediated Smad1/5/8, p38, ATF2 and CREB phosphorylation.
Animal experiment [2]:
Animal models	C57BL/6 mice
Dosage form	Intraperitoneal injection; 3 mg/kg every 12 h
Application	In Ad.Cre-injected, caALK2-expressing mice, treatment with LDN-193189 prevented radiographic lesions at P15. LDN-193189–treated mice appeared to preserve knee and ankle joints at P30 and P60. LDN-193189-treated mice showed no ectopic bone at P15 but did show enhanced cartilage formation in surrounding soft tissues. LDN-193189–treated mice showed mildly impaired range of motion even in the absence of radiographically visible disease at P30.
Other notes	Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.
