Polymeric synthetic host , azacrown-attached 2,6-pyridylene ethynylene polymer, was investigated for its saccharide recognition and the additive effect of triethylene tetramine-trifluoroacetic acid; heteroallosteric effects were observed on the basis of CD and UV/Vis analyses, which indicated saccharide-dependent stabilization and destabilization of helical complexes by the formation of pseudop...

UNLABELLED BACKGROUND Saccharide materials have been used for centuries as binding media, to paint, write and illuminate manuscripts and to apply metallic leaf decorations. Although the technical literature often reports on the use of plant gums as binders, actually several other saccharide materials can be encountered in paint samples, not only as major binders, but also as additives. In th...

evaluating fertilizer quality is important in selecting the appropriate fertilizers for agricultural production. in this experiment, the effectiveness of composite inorganic fertilizer (cif), composite organic fertilizer (cof) and foliar spray of multi-nutrients (fsmn) on the growth, yield, and fruit quality of cherry tomato (lycopersicon esculentum mill.) were compared. the results showed that...

Amphiphilic 2,6-pyridylene ethynylene "meta-ethynylpyridine" polymers having chiral oligo(oxyethylene) side chains were developed as hosts for saccharide recognition. The polymers were prepared via a Sonogashira reaction and fractionated by gel permeation chromatography (GPC). They showed circular dichroism (CD) activity due to their higher-order chiral helical structures, and their CD and UV-v...

We designed and synthesized phenylboronic acid as a molecular recognition model system for saccharide detection. The phenylboronic acid derivatives that have boronic acid moiety are well known to interact with saccharides in aqueous solution; thus, they can be applied to a functional interface of saccharide sensing through the formation of self-assembled monolayer (SAM). In this study, self-ass...

Dynamic proteoids are dynamic covalent analogues of proteins, which can be used as new adaptive biomaterials. We designed and synthesized a range of sugar-containing dynamic proteoid biodynamers based on the polycondensation of different types of amino acid and dipeptide hydrazides with a biological aliphatic dialdehyde and a nonbiological aromatic dialdehyde. By using the saccharide-based dial...

Among saccharides, the antibiotics of the aminoglycoside family are the best-studied class of molecules interacting with RNA. By binding to RNA targets, aminoglycosides act as inhibitors of protein biosynthesis, they interfere with protein-RNA interaction of retroviral regulatory elements, and they inhibit the catalytic action of ribozymes. Here, we survey the available data on molecular struct...
