Background: The 21-aminosteroid (U-74389G) is a nonglucocorticoid steroid that was synthesized to inhibit lipid peroxidation without the glucocorticoid activity. We recently demonstrated that the 21-aminosteroid administered to endotoxin shock mice reduces liver injury and improves the survival rate of mice through inhibition of nuclear factor-κB activation in the liver. The study was undertaken to...
Background: Lazaroids are nonglucocorticoid analogs of methylprednisolone with multiple actions. We investigated whether lazaroid U-74389G could attenuate endotoxin-induced liver injury. We hypothesized that U-74389G treatment may protect against hepatic injury by suppressing proinflammatory gene up-regulation through inhibition of activation of nuclear factor κB (NF-κB). We also compared the efficacy...
