Application

SC-26196 has been used as an inhibitor of delta6 (Δ6) fatty acid desaturase:
  • in mouse inner medullary collecting duct (IMCD3) and human (female) embryonic kidney (HEK) 293 cell culture as Dulbecco′s modified eagle′s medium (DMEM) component
  • in hepatic HepG2 cells
  • in glioblastoma cell lines to test its effect post-radiation treatments

Biochem/physiol Actions

SC-26196 is a Delta6 fatty acid desaturase (Delta6D) inhibitor. It specifically inhibited Delta6D activity with an IC(50) value of 100 nM. The rate-limiting step in arachidonic acid synthesis is the desaturation of dietary linoleic acid by Delta6D. SC-26196 completely prevented this conversion of linoleic acid to arachidonic acid.

The reactions catalyzed by the delta-5 and delta-6 desaturases (D5D/D6D), key enzymes responsible for highly unsaturated fatty acid (HUFA) synthesis, regenerate NAD+ from NADH. Here, we show that D5D/D6D provide a mechanism for glycolytic NAD+ recycling that permits ongoing glycolysis

The macrophage plays an important role in innate immunity to induce immune responses. Lipid replacement therapy has been shown to change the lipid compositions of mitochondria and potentially becomes an alternative to reduce the inflammatory response. We examined the effects

It has been reported that cell inflammation pathways contribute to the development of prostaglandin E2 (PGE2)-inhibitor of DNA-binding protein-1 (ID1)-dependent radio-resistance in glioblastoma. Here, we proposed that inhibiting delta-6-desaturase (D6D) could block arachidonic acid synthesis and PGE2 production, thereby reversing

Dietary deficiency of docosahexaenoic acid (C22:6 n-3; DHA) is linked to the neuropathology of several cognitive disorders, including anxiety. DHA, which is essential for brain development and protection, is primarily obtained through the diet or synthesized from dietary precursors, however

Non-invasively probing metabolites within single live cells is highly desired but challenging. Here we utilize Raman spectro-microscopy for spatial mapping of metabolites within single cells, with the specific goal of identifying druggable metabolic susceptibilities from a series of patient-derived melanoma
