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 .

Combined Proteomic and In Silico Target Identification Reveal a Role for 5-Lipoxygenase in Developmental Signaling Pathways
Cell Chem Biol 2018 Sep 20;25(9):1095-1106.e23.PMID:30251630DOI:10.1016/j.chembiol.2018.05.016
Identification and validation of the targets of bioactive small molecules identified in cell-based screening is challenging and often meets with failure, calling for the development of new methodology. We demonstrate that a combination of chemical proteomics with in silico target prediction employing the SPiDER method may provide efficient guidance for target candidate selection and prioritization for experimental in-depth evaluation. We identify 5-lipoxygenase (5-LO) as the target of the Wnt pathway inhibitor Lipoxygenin. Lipoxygenin is a non-redox 5-LO inhibitor, modulates the β-catenin-5-LO complex and induces reduction of both β-catenin and 5-LO levels in the nucleus. Lipoxygenin and the structurally unrelated 5-LO inhibitor CJ-13,610 promote cardiac differentiation of human induced pluripotent stem cells and inhibit Hedgehog, TGF-β, BMP, and Activin A signaling, suggesting an unexpected and yet unknown role of 5-LO in these developmental pathways.
