Luteolin improves vasoconstriction function and survival of septic mice via AMPK/NF-κB pathway

ABSTRACT: Septic shock, the leading cause of death in sepsis, is related to vasoconstriction dysfunction. To investigate the effects of Luteolin (LTL), a flavonoid polyphenol compound, on vasoconstriction dysfunction in septic mice and the underlying mechanism, cecal ligation and puncture (CLP) surgery was performed on wild-type C57BL/6 mice to induce septic shock. Mice were intraperitoneally injected with 0.2 mg/kg LTL within 10 min after CLP surgery with or without 20 mg/kg Compound C (AMPK inhibitor) (CC) 1 h before CLP surgery, and re-administrated every 12 h. The survival rate, systolic arterial pressure (SAP), diastolic arterial pressure (DAP), and mean arterial pressure (MAP) were explored. After the mice were sacrificed, the vasoconstriction function, inflammatory indicators, and possible re
