SC-26196 is a D6D inhibitor (IC50 = 0.2 µM in a rat liver microsomal assay) that completely blocks the conversion of linoleic acid to arachidonic acid (AA). SC-26196 inhibited the desaturation of 2 microM [1-14C] 18:2n-6 by 87-95% in cultured human skin fibroblasts, coronary artery smooth muscle cells, and astrocytes. By contrast, SC-26196 did not affect the conversion of [1-14C]20:3n-6 to 20:4 in the fibroblasts, demonstrating that it is selective for delta6-desaturase.

How to use

In Vitro:

SC-26196 (200 nM) inhibits proliferation of peripheral blood mononuclear cells (PBMCs), but Not Jurkat Cells.

In Vivo:

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.
