Direct pulmonary delivery of solubilized curcumin reduces severity of lethal pneumonia.

ABSTRACT: Acute respiratory distress syndrome (ARDS), the most severe form of acute lung injury, is associated with reduced lung compliance and hypoxemia. Curcumin exhibits potent anti-inflammatory properties but has poor solubility and rapid plasma clearance. To overcome these physiochemical limitations and uncover the full therapeutic potential of curcumin in lung inflammation, in this study we utilized a novel water-soluble curcumin formulation (CDC) and delivered it directly into the lungs of C57BL/6 mice inoculated with a lethal dose of Klebsiella pneumoniae (KP). Administration of CDC led to a significant reduction in mortality, in bacterial presence within blood and lungs, as well as in lung injury, inflammation, and oxidative stress. The expression of Klebsiella hemolysi
