Inhibition of rotavirus infection by treatment with antioxidants, nonsteroidal antiinflammatory drugs and peroxisome proliferator-activated receptor gamma agonists. NAC and AA can inhibit the production of ROS, whereas NAC can also affect IκB preventing the cytoplasmic activation of NF-κB. NAC can further inhibit nuclear phosphorylated NF-κB preventing the transcription of pro-inflammatory genes. NSAIDs such as KTP, IND and DCF inhibit Cox-2 leading to a significant inhibition of prostaglandin accumulation. On the other hand, ASA and IBF inhibit activation of NF-κB suppressing the transcription of IFN-α, IFN-β and IFN-γ, cytokines and interleukins. These NSAID treatments significantly inhibit rotavirus infections in cultured cells and mice. PPARγ agonists such as 13(S)-hydroxyoctadecadienoic acid (HODE), ALA and DHA, and thiazolidinediones such as PGZ, RGZ, and 2, 4-thiazolidinedione (TZD) activate PPARγ leading to inhibition of cytoplasmic NF-κB. PPARγ can heterodimerize with the RA-activated RXR for promoting transcription of anti-inflammatory genes. This complex can also cause inhibition of phosphorylated NF-κB which in turn leads to decreased transcription of pro-inflammatory genes. MIT, ER, and PROT are indicated.
