NSC 12

NSC 12 is an extracellular trap for fibroblast growth factor 2 (FGF2) that binds FGF2 (Kd = 51 µM) and interferes with its interaction with FGFR1, without affecting the ability of FGF2 to bind heparin or heparin sulfate proteoglycans (HSPGs). NSC 12 also binds several other, but not all, FGF isoforms with Kd values ranging between 16 and 120 µM, preventing them from forming HSPG/FGF/FGFR ternary complexes. NSC 12 inhibits FGF-dependent angiogenesis and tumor cell proliferation in vitro and reduces tumor growth in mice.Formal Name: (3beta)-24,24,24-trifluoro-23-(trifluoromethyl)-21-norchol-5-ene-3,20,23-triol.
