Biological Activity for SC 26196

SC 26196 is a selective fatty acid desaturase 2 (FADS2, also known as Δ6 desaturase) inhibitor (IC50 = 0.2 μM in vitro). Displays selectivity over FADS1 and stearoly-CoA 9-desaturase (Δ5 desaturase and SCD-1/Δ9 desaturase, respectively) (IC50 values are >200 μM in vitro). Exhibits anti-inflammatory properties in a mouse edema model. Eliminates CSCs from ovarian cancer cell lines and inhibits sphere formation in vitro.
