Biological Activity
Lipoxygenin is an inhibitor of 5-lipoxygenase (5-LO) with an IC50 value of 5 μM for inhibition of 5-LO product synthesis in isolated human granulocytes stimulated with the cation ionophore A23187 .1 It inhibits hedgehog-dependent signaling in Shh-LIGHT2 cells and TGF-β-, activin A-, bone morphogenic protein (BMP)-, or Wnt-dependent signaling in HEK293T cells (IC50s = 9.3, 3.2, 8.2, 9.6, and 3.7 μM, respectively, in luciferase reporter assays). Lipoxygenin (5 and 10 μM) increases levels of troponin T (TnnT), a marker of cardiomyocyte differentiation, in human induced pluripotent stem cells (iPSCs) stimulated with BMP4 and the glycogen synthase kinase 3 (GSK3) inhibitor CHIR99021 .
