A cell-permeable pyrrazolopyrimidine compound that inhibits against R/VEGFR2, ALK2/BMPR-I, AMPK kinase activity (IC50=25.1, 148, and 234.6nM, respectively), while exhibiting much reduced or little effect toward ALK5/TGFbR-I, ZAPK, Syk, PKCth, PKA, or JAK3. Shown to block both BMP pathway-dependent dorsoventral development (EC100=2.5uM) and VEGF signaling-dependent intersomitic vessel formation (EC50=5uM) in zebrafish embryo in vivo. Commonly used in combination with AMPK activators AICAR and/or Metformin for studying AMPK-dependent cellular events in vitro and physiological responses in animals in vivo.
