Abstract
Antrafenine is a drug initially designed for anti-inflammation uses. In this work we have synthesized a library of its structural analogs and tested the anti-influenza activities. These analogs belong to a group of 2-(quinolin-4-yl)amino benzamides or 2-(quinolin-4-yl)amino benzoate derivatives. Best performers were identified, namely 12, 34, 41, with IC50 against A/WSN/33 (H1N1) of 5.53, 3.21 and 6.73 μM respectively. These chemicals were also effective against A/PR/8/34 (H1N1), A/HK/1/68 (H3N2) and B/Florida/04/2006 viruses. Time-of-addition study and minigenome luciferase reporter assay both supported that the compounds act on the ribonucleoprotein (RNP) components. Using 34 and 41 as representative compounds, we determined by microscale thermophoresis that this group of compounds bind to both PA C-terminal domain and the nucleoprotein (NP) which is the most abundant subunit of the RNP. Taken together, we have identified a new class of anti-influenza compounds with dual molecular targets and good potential to be further developed. IMPORTANCE: The influenza viruses, especially influenza A and B subtypes, cause many deaths each year. The high mutation rate of the virus renders available therapeutics less effective with time. In this work we identify a new class of compounds, structurally similar to the anti-inflammation drug antrafenine, with good potency against influenza A strains. The IC50 of the best performers are within low micromolar range and thus have good potential for further development.

Abstract
In this study, a series of 4-[(quinolin-4-yl)amino]benzamide derivatives as the novel anti-influenza agents were designed and synthesized. Cytotoxicity assay, cytopathic effect assay and plaque inhibition assay were performed to evaluate the anti-influenza virus A/WSN/33 (H1N1) activity of the target compounds. The target compound G07 demonstrated significant anti-influenza virus A/WSN/33 (H1N1) activity both in cytopathic effect assay (EC50 = 11.38 ± 1.89 µM) and plaque inhibition assay (IC50 = 0.23 ± 0.15 µM). G07 also exhibited significant anti-influenza virus activities against other three different influenza virus strains A/PR/8 (H1N1), A/HK/68 (H3N2) and influenza B virus. According to the result of ribonucleoprotein reconstitution assay, G07 could interact well with ribonucleoprotein with an inhibition rate of 80.65% at 100 µM. Furthermore, G07 exhibited significant activity target PA−PB1 subunit of RNA polymerase according to the PA−PB1 inhibitory activity prediction by the best pharmacophore Hypo1. In addition, G07 was well drug-likeness based on the results of Lipinski’s rule and ADMET prediction. All the results proved that 4-[(quinolin-4-yl)amino]benzamide derivatives could generate potential candidates in discovery of anti-influenza virus agents.

Abstract
1. Differences in the expression of CIDEa and CIDEc in 20 different tissues were examined. Both CIDEa and CIDEc mRNA transcripts were predominantly but variably expressed in white adipose tissue (WAT) but were also expressed at moderate levels in the kidney and liver and at lower levels in the ovary. Interestingly, among WAT types, both CIDEa and CIDEc were expressed at the lowest levels in heart coronary WAT. 2. To better understand the roles of CIDEa and CIDEc in the fat deposition of broiler chickens, the differences in lipid droplet (LD) size and mRNA levels of CIDEa and CIDEc between lean-type and fat-type broiler chicken lines were studied. LD sizes were larger in fat-type broiler lines, and CIDEa and CIDEc mRNA levels in white adipose, kidney and liver tissues were significantly higher in fat-type broiler lines than in their lean counterparts. 3. Developmental expression patterns of CIDEa and CIDEc mRNA were analysed in different tissue types (WAT, liver and kidney) in Arbor Acres broiler chickens, and CIDEa and CIDEc mRNA expression levels increased during sequential developmental stages, achieving peak expression levels at week 6. 4. These observations suggest that the functions of CIDEa and CIDEc reflect inherent characteristics of lipid metabolism that contribute to the differences in fat deposition between strains. The results in this study contribute to a more robust understanding of the tissue distribution and expression patterns of CIDEa and CIDEc mRNA and facilitate further research concerning the molecular mechanism underlying fat deposition in broiler chickens.
