LDN-193189 HCl Usage And Synthesis

Uses

4-(6-(4-(Piperazin-1-yl)phenyl)pyrazolo[1,5-a]pyrimidin-3-yl)quinoline Hydrochoride is a selective inhibitor of bone morphogenetic protein (BMP) pathway, useful in the treatment of diseases.

Uses

LDN-193189 HCl has been used to inhibit BMP type I receptor activity to study the pathogenesis of fibrodysplasia ossificans progressive, a congenital hyperossification disorder, and to examine the role of osteogenesis in prostate tumor metastases in bone.

Biological Activity

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].
