    氢键调控的超分子纳米结构及其对多价结合的影响
    摘要:
    在这里,我们描述了氢键调节的纳米结构,热力学和两个博拉两亲物NDI-1和NDI-2的多价结合,这两个疏水性萘二酰亚胺通过H键合基团与亲水性楔形连接,并且两个分子上都有一个葡萄糖部分武器。NDI-1和NDI-2的不同之处在于单个的H键合基团,即酰肼或酰胺,它们分别触发囊泡和圆柱形胶束的形成。尽管扩展的H键确保了头对头方向的堆叠并在两个系统中形成了一系列附加的葡萄糖部分,但自适应圆柱结构对伴刀豆球蛋白A(ConA)的囊泡表现出更高的多价结合能力。

  • Carbohydrate based cellulase inhibitors as feeding stimulants in termites
    申请人:Scharf Michael E.

    A method, composition and system for controlling termites wherein single carbohydrate-based compounds are used as both cellulase inhibitors and feeding stimulants. Di-saccharides, cellobioimidazole (CBI), fluoro-methyl cellobiose (FMCB), and mono-saccharides, fluoro-methyl glucose (FMG) and analogs thereof inhibit termite cellulose digestion, which leads to starvation or stimulates termite feeding to cause mortality. CBI, FMCB and FMG were tested against enzyme fractions that represented endogenous (foregut/salivary gland/midgut) and symbiotic (hindgut) termite cellulases in vitro and in vivo. Feeding stimulation by di-saccharides results in greater cellulase inhibitor intake throughout midrange concentrations (1 mM-10 mM), which is associated with significant termite mortality. In contrast, the monosaccharide inhibitor, FMG did not stimulate feeding, but did inhibit feeding at concentrations above 1 mM, causing mortality. With modification to create longer β-glycosidic chain lengths, the cellulase inhibitors identified herein can also be targeted to endoglucanase activity for increased efficacy and use as novel termite control compositions.
    一种用于控制白蚁的方法、组合物和系统,其中单一的基于碳水化合物的化合物被用作纤维素酶抑制剂和摄食刺激剂。双糖,赛洛比咪唑(CBI),氟甲基赛洛生(FMCB),以及单糖,氟甲基葡萄糖(FMG)及其类似物抑制白蚁纤维素消化,导致饥饿或刺激白蚁摄食以引起死亡。在体外和体内对CBI、FMCB和FMG进行了与代表内源(前肠/唾液腺/中肠)和共生(后肠)白蚁纤维素酶的酶分数的测试。双糖的摄食刺激导致在中等浓度范围(1 mM-10 mM)内更多的纤维素酶抑制剂摄入,与显著的白蚁死亡相关。相比之下,单糖抑制剂FMG并未刺激摄食,但在超过1 mM的浓度下抑制摄食,导致死亡。通过修改以创建更长的β-葡苷链长度,本文鉴定的纤维素酶抑制剂也可以针对内切酶活性,以提高功效并用作新型白蚁控制组合物。

    Carbohydrate–ferrocene conjugates were synthesized and showed that the ferrocene entity appeared to be confined to a low volume so that proton NMR spectroscopy revealed 3 to 4 signals for substituted cyclopentadienyl instead of two usually.
