Four classes of core-expanded naphthalene diimides （la, lb, 2a, 2b, 3 and 4） that bear different elec- tron-deficient sulfur heterocycles were designed and synthesized. The solution-processed thin films of la, 2a, 3 and 4 operated well in air as n-channel organic transistors with electron mobility ranging from MO 6 to 0.14 cm2/Vs, depending on the different conjugated backbones. The thin film microstructure studies were also carried out to un- derstand the variations of the electron mobility for thin films of la, 2a, 3 and 4.

Azulene, one of representative nonbenzenoid aromatic hydrocarbons, exhibits unique molecular structure and distinctive physical and chemical properties. Herein, azulenoisoindigo(Az II), an azulene-based isoindigo analogue, is designed and synthesized, which has a twisted molecular backbone and R/Sisomers in single crystals. Interestingly, Az II shows the characteristics of both isoindigo and azulene,such as reversible redox behavior and reversible proton responsiveness. UV-vis-NIR,^(1)H NMR and electron paramagnetic resonance(EPR) measurements were carried out to get insights into the possible mechanism of the proton-responsive property of Az II. The results demonstrated that only one azulenyl moiety of molecule of Az II was protonated and deprotonated, and the protonated Az II can be further oxidized to form azulenium cation radicals.

Objectives: Helminth or it’s derived protein are potent inducers of T helper type 2(Th2) response and have a regulatory role, notably on allergic or autoimmune diseases. Now it’s immunomodulation in host has also been shown to have therapeutic implications in sepsis which is characterised with the aberrant production of pro-inflammatory. Herein we have evaluated the therapeutic effect of recombinant cystatin from Schistosoma japonicum(r Sjcystatin) in a mice model of polymicrobial ***: The mice model with sepsis was established with cecal ligation and puncture(CLP). BALB/c mice were treated intraperitoneally(i.p.) with r Bm Cys(10, 25 or 50 μg/dose) 0.5 h after the CLP operation, and persistent observation was performed for 72 h. Blood samples and tissues were collected at 12 h after CLP. Cytokines in serum were measured by ELISA. The pathological damage of liver and kidney tissue were stained with hematoxylin-eosin(HE), and the function of liver and kidney was examined 12 h after the CLP operation by fully automatic chemistry ***: Treatment with r Sjcystatin in mice ameliorated the pathological damage degree and the increased serum levels of ALT, AST, BUN, and Cr caused by CLP-induced sepsis in liver and kidney of mice. While the level of TNF-α, IL-1β and IL-6 was down-regulated, the IL-10 and TGF-β expression was up-regulated in the serum of CLP-induced sepsis mice treated with r Sjcystatin. The amelioration effect in CLP-induced sepsis mice was in a dose dependent manner. Conclusions: The results of this study indicate r Sjcystatin can counterbalance exacerbated pro-in?ammatory immune responses that occur during sepsis, improving survival. The anti-inflammatory effect of r Sjcystatin provide evidential support for this protein to be used as a promising therapeutic agent in sepsis.
