Oligomycin
This product consists of a mixture of oligomycins A, B and C. Oligomycins are macrolide antibiotics that exhibit antibacterial activity. Oligomycins suppress oxidative phosphorylation in the mitochondria by inhibiting K+-activated current of the Na+/K+ ATPase. In vitro, oligomycins inhibit IFN-γ- and TNF-α-induced reductions in transepithelial resistance and paracellular permeability. Oligomycins also inhibit the increase in expression and phosphorylation of MLC, preventing intestinal epithelial barrier dysfunction induced by inflammatory cytokines.
