Xylo-LNA analogues

Based on the above and on the remarkable properties of the 2′-O,4′-C-methylene bridged LNA monomers it was decided to synthesise oligonucleotides comprising one or more 2′-O,4′-C-methylene-β-D-xylofuranosyl nucleotide monomer(s) as the first stereoisomer of LNA modified oligonucleotides. Modelling clearly indicated the xylo-LNA monomers to be locked in an N-type furanose conformation. Whereas the parent 2′-deoxy-β-D-xylofuranosyl nucleosides were shown to adopt mainly an N-type furanose conformation, the furanose ring of the 2′-deoxy-β-D-xylofuranosyl monomers present in xylo-DNA were shown by conformational analysis and computer modelling to prefer an S-type conformation thereby minimising steric repulsion between the nucleobase and the 3′-O-phopshate group (Seela, F.; Wömer, Rosemeyer, H. Helv. Chem. Acta 1994, 77, 883). As no report on the hybridisation properties and binding mode of xylo-configurated oligonucleotides in an RNA context was believed to exist, it was the aim to synthesise 2′-O,4′-C-methylene-β-D-xylofuranosyl nucleotide monomer and to study the thermal stability of oligonucleotides comprising this monomer. The results showed that fully modified or almost fully modified Xylo-LNA is useful for high-affinity targeting of complementary nucleic acids. When taking into consideration the inverted stereochemistry at C-3′ this is a surprising fact. It is likely that Xylo-LNA monomers, in a sequence context of Xylo-DNA monomers, should have an affinity-increasing effect.

Sodium alginate oligosaccharide coated slow-release fertilizer and preparation and application thereof

The invention discloses a sodium alginate oligosaccharide coated slow-release fertilizer. Coated materials of the slow-release fertilizer contain sodium alginate oligosaccharide and an auxiliary coated material, wherein sodium alginate oligosaccharide is composed of two structural units, namely a-L-mannuronic acid and b-D-guluronic acid. The two structural units are linked in three ways by 1,4-glucosidic bond, so as to form a unbranched linear segmented copolymer. The coated slow-release fertilizer is mainly applied in commercial crops, fruit and vegetable crops, grain crops, economic forest, flowers and plants, traditional Chinese medicinal materials, lawn and the like. By introducing organism-derived sodium alginate oligosaccharide into the coated materials of the slow-release fertilizer, nutritive elements required by plant growth and development can be supplemented by a slow-release approach, and the plant growth promoting effect of sodium alginate oligosaccharide also can be performed so as to finally achieve the yield-increasing effect. In addition, a medicament prepared by using sodium alginate oligosaccharide as the main coated material composition is safe and nontoxic and has advantages of low cost, small application amount and the like.
