Uses
5-[6-[4-(1-Piperazinyl)phenyl]pyrazolo[1,5-a]pyrimidin-3-yl]quinoline, contains the pyrazolo[1,5-a]pyrimidine scaffold, acting as a novel and selective bone morphogenetic protein receptor (BMP) inhibitors. It is a COVID19-related research product.
Biological Activity
ldn-212854 is a selective inhibitor of bone morphogenetic protein (bmp) signaling with ic50 value of 1.2nm [1].in the kinase assay, ldn-212854 shows inhibitory activities against caalk2 and caalk5 with ic50 values of 16nm and 2μm, respectively. it demonstrates that ldn-212854 is selective against bmp over tgf-β signaling. besides that, the inhibition of caalk2 caused by ldn-212854 is 6- and 10-fold more potent than that of caalk1 and caalk3, respectively. in c2c12 cells transfected with bmp receptors, ldn-212854 also exerts preferential inhibition against caalk2. furthermore, in a transgenic alk2q207d model of heterotopic ossification, treatment of ldn-212854 prevents the formation of heterotopic bone and preserves limb range of motion [1].
Biochem/physiol Actions
LDN-212854 is also known as 5-[6-[4-(1-Piperazinyl)phenyl]pyrazolo[1,5-a]pyrimidin-3-yl]-quinoline. LDN-212854 prevents heterotopic ossification in an inducible mutant ALK2 (activin receptor-like kinase 2).
