TRAF3 Positively Regulates Host Innate Immune Resistance to Influenza A Virus Infection.

Tumor necrosis factor receptor-associated factor 3 (TRAF3) is one of the intracellular adaptor proteins for the innate immune response, which is involved in signaling regulation in various cellular processes, including the immune responses defending against invading pathogens. However, the defense mechanism of TRAF3 against influenza virus infection remains elusive. In this study, we found that TRAF3 could positively regulate innate antiviral response.

Essential Oil-Rich Chinese Formula Luofushan-Baicao Oil Inhibits the Infection of Influenza A Virus through the Regulation of NF-B P65 and IRF3 Activation.

Background: Luofushan-Baicao Oil (LBO) is an essential oil-rich traditional Chinese medicine (TCM) formula that is commonly used to treat cold, cough, headache, sore throat, swelling, and pain. However, the anti-influenza activities of LBO and the underlying mechanism remain to be investigated.

Methods: The anti-influenza activity of LBO was tested with methyl thiazolyl tetrazolium (MTT) and plaque assays.

Identification of imidazo[4,5-c]pyridin-2-one derivatives as novel Src family kinase inhibitors against glioblastoma.

Glioblastoma multiforme (GBM) is the most common and malignant primary brain tumour in the central nervous system (CNS). As the ideal targets for GBM treatment, Src family kinases (SFKs) have attracted much attention. Herein, a new series of imidazo[4,5-c]pyridin-2-one derivatives were designed and synthesised as SFK inhibitors.

Multiple modes of action of myricetin in influenza A virus infection.

Influenza A virus remains a major threat to public health worldwide after its first pandemic. Scientists keep searching novel anti-influenza drugs, of which natural products present to be an important source. Myricetin, a natural flavonol compound, which exists in many edible plants, which has a wide range of biological activities, but its anti-influenza A virus activity is ambiguous.

Dihydromyricetin is a new inhibitor of influenza polymerase PB2 subunit and influenza-induced inflammation.

Development of new and effective anti-influenza drugs is critical for the treatment of influenza virus infection. The polymerase basic 2 (PB2) subunit as a core subunit of influenza A virus RNA polymerase complex is considered to be an attractive drug target for anti-influenza drug discovery. Dihydromyricetin, as a natural flavonoid, has a wide range of biological activities, but its anti-influenza A virus activity is ambiguous.

Discovery of dihydropyrrolidones as novel inhibitors against influenza A virus.

More effective prophylactic and therapeutic strategies to combat influenza viruses are urgently required worldwide because the conventional anti-influenza drugs are facing drug resistance. Here, dihydropyrrolidones (DHPs), the products of an efficient multi-components reaction, were found to possess good activities against influenza A virus (IAV). Primary structure-activity relationship indicated that the activities of DHPs were greatly influenced by substituents and four of them had IC values lower than 10 μM (DHPs 5-2, 8, 14 and 19: IC = 3.

Isocorilagin, isolated from Canarium album (Lour.) Raeusch, as a potent neuraminidase inhibitor against influenza A virus.

Canarium album (Lour.) Raeusch (C. album) as a normally medicinal and edible plant has been used widely in Asian countries and is considered a source of phytochemicals that are beneficial to human health.
