To develop novel antiviral agents, some novel conjugates between ferulic acid and eugenol or isoeugenol were designed and synthesized by the link reaction. The antiviral activities of compounds were evaluated using the half leaf dead spot method. Bioassay results showed acceptable antiviral activities of some conjugates against the tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV). Compounds A9, A10, E1, and E4 showed remarkable curative, protective, and inactivating effects on TMV and CMV at 500 μg mL-1. Notably, these compounds exhibited excellent protective effects on TMV and CMV. The EC50 values of compounds A9, A10, E1, and E4 against TMV were 180.5, 169.5, 211.4, and 135.5 μg mL-1, respectively, and those against CMV were 210.5, 239.1, 218.4, and 178.6 μg mL-1, respectively, which were superior to those of ferulic acid (471.5 and 489.2 μg mL-1), eugenol (456.3 and 463.2 μg mL-1), isoeugenol (478.4 and 487.5 μg mL-1), and ningnanmycin (246.5 and 286.6 μg mL-1). Then, the antiviral mechanisms of compound E4 were investigated by determining defensive enzyme activities and multi-omics analysis. The results indicated that compound E4 resisted the virus infection by enhancing defensive responses via inducing the accumulation of secondary metabolites from the phenylpropanoid biosynthesis pathway in tobacco.
Synthesis of hydroxyethyl methyl morpholinium azide (HEM Morph)N3: A highly efficient new task specific azide-based ionic liquid and its dual application as an azide source and media for synthesis of some novel aromatic O-oxime ethers-1,2,3-triazole conjugates as a potential antihistaminic agents

The synthesis, characterization and application of hydroxyethyl methyl morpholinium azide (HEM Morph)N3 as a new azide-based ionic liquid (ABIL) has been described. (HEM Morph)N3 is used as a source of azide and reaction media for three components ‘Click’ Huisgen cycloaddition reaction between O-propargyl oxime ether and alkyl bromide to acquire novel aromatic O-oxime ethers-1,2,3-triazole conjugates as potential antihistaminic agents in good yields. The influence of parameters like temperature, amount of IL, type of azide-based ionic liquids and its reusability is investigated. The (HEM Morph)N3 is proved to be an efficient, thermally stable, inexpensive and recyclable azide-based ionic liquid which can be easily synthesized and used as both azide's source and reaction media for ‘Click’ Huisgen cycloaddition reaction.

Three series of new homoserine lactone analogs were efficiently synthesized starting from methionine and further evaluated for their antiproliferative activity against different cancer cell lines. Among these compounds, some of the chalcone containing compounds 6a-n showed acceptable antiproliferative activity against prostate cancer cells DU145 and PC-3 with the IC50 values less than 10 μM. Compounds 6c, 6e and 6h inhibited growth of DU145 and PC-3 cells at low micromolar levels with the IC50 values ranging from 3.0 to 5.0 μM, much more potent than natural OdDHL. Compound 6e concentration-dependently inhibited colony formation and cell migration of DU145 cells. A synergistic effect on the growth inhibition and the apoptosis of DU145 cells was observed when compound 6e was used in combination with TRAIL. OdDHL or 6e treatment concentration-dependently activated TRAIL death receptor DR5 which may account for the observed synergistic effect of 6e or OdDHL with TRAIL on the growth inhibition and cell apoptosis. Compound 6e also inhibited migration of DU145 cells in a time- and concentration-dependent manner. The data suggest that quorum sensing molecules OdDHL and 6e may improve the sensitivity of DU145 cells toward TRAIL via activating DR5, compound 6e may be used as a potential lead compound for developing new TRAIL receptor agonists.
