What is 5-(2-Phenyl-pyrazolo[1,5-a]pyridin-3-yl)-1H-pyrazolo[3,4-c]pyridazin-3-ylamine?

The Uses of 5-(2-Phenyl-pyrazolo[1,5-a]pyridin-3-yl)-1H-pyrazolo[3,4-c]pyridazin-3-ylamine

FR180204 has been used as ERK inhibitor:

to block extracellular-signal-regulated kinase (ERK) in order to validate whether homeobox B7 (HOXB7) regulates the migration and proliferation process via AKT/mitogen-activated protein kinases (MAPK) signaling
of extracellular-signal-regulated kinase (ERK) to study the effects of signaling pathway inhibitors on differentiation and cell traction stress
to determine if phosphorylation of this signaling protein is essential for mesenchymal stromal cell (MSC) derived therapeutic efficacy

What are the applications of Application

ERK Inhibitor II, FR180204 is a novel ERK-selective inhibitor
