Andrographolide sulfate inhibited NF-?B activation and alleviated pneumonia induced by poly I:C in mice.

ABSTRACT: Pneumonia is a common illness that continues to be the major killer of remaining to be a significant source of morbidity and mortality in the patient population. Many microorganisms cause pneumonia, and now concern is turning to the importance of the cause the new therapies for viral pneumonia. In the current study, we report the effect of andrographolide sulfonate, a water-soluble form of andrographolide (trade name: Xi-Yan-Ping Injection), on poly I: C-induced pneumonia. Andrographolide sulfonate was administrated through intraperitoneal injection to mice with poly I: C-induced pneumonia. Recruitment of airway inflammatory cells, alteration of lung histological induced by Poly I: C were significantly ameliorated by andrographolide sulfonate. The protein levels of pro-inflammatory cytokines in bronchoalveolar fluid (BALF) and serum were reduced by andrographolide sulfonate treatment. The levels of MUC5AC and MUC5B in lung tissue were also suppressed. These results reveal that andrographolide sulfate remarkably alleviated pneumonia induced by poly I:C in mice. Moreover, andrographolide sulfonate markedly inhibited the activation of nuclear factor-?B (NF-?B). Taken together, we demonstrated that andrographolide sulfonate ameliorated poly I: C-induced pneumonia in mice, suggesting the possible use of andrographolide sulfonate for virus-induced pneumonia in clinical.
