Abstract

|
CKD-712 is a 1-naphthyl analog of higenamine that has been reported to have potent antiinflammatory and thus anti-sepsis effects. The purpose of this study was to investigate the potential of CKD-712 as a medicine for sepsis and to confirm its protective effects on organs in animal sepsis models. Pretreatment with CKD-712 dose-dependently increased survival rate in a lipopolysaccharide-induced sepsis model in mice. Body temperature decrease, an important pre-symptom of septic death, was also prevented by CKD-712. CKD-712 still significantly increased survival rate even when administered one and four hours after lipopolysaccharide injection. Therapeutic efficacy of CKD-712 was also confirmed against sepsis following zymosan-induced endotoxemia and in cecal ligation and puncture surgery in mice. In a disseminated intravascular coagulation model in rats, CKD-712 showed organ-protective effect by reducing serum glutamate-oxaloacetate transaminase, glutamate-pyruvate transferase, blood urea nitrogen, and creatinine levels. CKD-712 also prevented histological damage to the lung and liver. In this same model, CKD-712 showed anti-inflammatory effects through decreases in tumor necrosis factor-α and interleukin-6 in the blood and reduced translocation of nuclear factor-κB to the nuclei of lung cells. CKD-712 administration also diminished infiltration of leukocytes into the lung and liver. Taken together, these results show that CKD-712 has excellent potential as an effective medicine for sepsis.
