SC-26196

SC-26196 is a potent, orally active Delta6 desaturase (D6D) inhibitor (IC50=0.2 µM in a rat liver microsomal assay). Antiinflammatory properties[1].

IC50: 0.2 µM (Delta6 desaturase in a rat liver microsomal assay)[1]

SC-26196 (200 nM) inhibits proliferation of peripheral blood mononuclear cells (PBMCs), but Not Jurkat Cells[2]. Cell Proliferation Assay[2] Cell Line: PBMCs and Jurkat cells Concentration: 200 nM Incubation Time: 96 hours for PBMCs; 144 hours for Jurkat cells Result: Treatment of PBMCs significantly decreased the proportion of cells that underwent division, the division index and proliferation index. Did not alter cell proliferation significantly in Jurkat cells.

SC-26196 ( included in the diet at 0, 0.07, 0.21, or 0.7 mg/kg diet to achieve dosages of 0, 10, 30, and 100 mg/kg per day) causes a decrease in the calculated Δ6-desaturase index in both adipose tissue and liver. Feeding 100 mg SC-26196 per kg BW per day inhibits the Δ6-desaturase enzyme[3]. Animal Model: Male mice (12- or 15-week-old)[3] Dosage: 0, 10, 30, and 100 mg/kg per day Administration: Included in the diet at 0, 0.07, 0.21, or 0.7mg/kg diet to achieve dosages of 0, 10, 30, and 100mg/kg per day. Result: Caused a decrease in the calculated Δ6-desaturase index in both adipose tissue and liver.
