Application

4-Octyl itaconate has been used:
  • to study its anti-inflammatory effects in macrophages
  • to treat bone-marrow-derived macrophages (BMDMs) for BMDM stimulation with nuclear factor-erythroid factor 2-related factor 2 (NRF2)-activating carboxylic acid compounds
  • to study its effects on collagen1 expression in systemic Sclerosis (SSc) dermal fibroblasts

Biochem/physiol Actions

4-Octyl itaconate (4-OI) possesses anti-inflammatory effects. It can obstruct glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and glycolysis in macrophages. It can be a good substitute to itaconate due to its thiol reactivity. The electrophilic α and β-unsaturated moieties of 4-OI might help to alkylate the thiol in cysteine residues of proteins through Michael reaction.
The endogenous metabolite itaconate has recently emerged as a regulator of macrophage function. 4-Octyl itaconate is a cell-permeable itaconate derivative that decreases cytokine production and is protective against lipopolysaccharide-induced lethality in vivo. Esterases in mouse myoblast cells and macrophages hydrolyze it to itaconate, which alkylates cysteine residues on KEAP1, allowing the transcription factor Nrf2 to increase the expression of anti-oxidant and anti-inflammatory downstream genes.

The cellular protein SAMHD1 is important for DNA repair, suppressing LINE elements, controlling deoxynucleoside triphosphate (dNTP) concentrations, maintaining HIV-1 latency, and preventing excessive type I interferon responses. SAMHD1 is also a potent inhibitor of HIV-1 and other significant viral pathogens.

Activated macrophages switch from oxidative phosphorylation to aerobic glycolysis, similar to the Warburg effect, presenting a potential therapeutic target in inflammatory disease. The endogenous metabolite itaconate has been reported to regulate macrophage function, but its precise mechanism is not clear.
