Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Tou Nong Powder (TNP), a classical Chinese medicinal formula originated from the Chinese Ming Dynasty, has been applied to treat skin ulcers in patients with deficient constitutions. According to theory of traditional Chinese medicine, colonic ulcers share similar pathological conditions with skin ulcers, and consequently, TNP has been applied to ulcerative colitis (UC) safely and effectively. AIM OF STUDY To investigate whether TNP obstructs 2,4,6-trinitrobenzene sulfonic acid (TNBS) induced enteric inflammation through regulation of NLRP3 inflammasome and attenuating enteric pyroptosis. MATERIALS AND METHODS Network pharmacology and UPLC-Q-TOF/MS were operated to identify compounds and pharmacological potential targets. The therapeutic effects of TNP were assessed on TNBS induced colitis via general symptoms (disease activity index, colonic weight and length) and histopathological observation. The NF-κB/NLRP3/Caspase-1/GSDMD signaling pathway regulation was investigated by Western blot and real time reverse transcription polymerase chain reaction (RT-qPCR). RESULTS TNP ameliorates the disease activity index, reverses the increase of colonic weight increase, alleviates colonic shortening and colonic histopathological injury. A decrease in tumor necrosis factor α (TNF-α), diamine oxidase (DAO), intercellular adhesion molecule-1 (ICAM-1), and endo-toxin (ET) were investigated in peripheral circulation. Moreover, TNP significantly obstructed the NF-κB/NLRP3/Caspase-1/GSDMD signaling pathway. CONCLUSION TNP displays a promising therapeutic effect on UC via suppressing NF-κB/NLRP3/Caspase-1/GSDMD signaling pathway and reducing the expression of IL-1β and IL-18.
