A carbohydrate-linked hypericinic photosensitizing agent
Zuschrader, Joachim,Schoefberger, Wolfgang,Falk, Heinz
, p. 1387 - 1390 (2008)
With respect to an enhanced solubility under physiological conditions, a carbohydrate-containing hypericin-based second-generation photosensitizer was prepared. Its photochemical properties were tested by means of the light-sensitized destruction of bilir

The invention relates to a glucosamide compound and a preparation method thereof. The glucosamide compound has a structure as shown in the formula (I). In the formula (I), R is methoxy group, nitro group, amino-group, hydroxyl group, C1-4 alkyl group or halogen, n is the number of substituent groups, and n is 1 or 2. The glucosamide compound is simple to prepare, has excellent plant induced resistance activity, and can be used as a plant induced resistance agent for controlling cucumber bacterial angular leaf spot, cucumber target leaf spot and tomato late blight. The invention also relates to a plant induced resistant agent containing the compound.

The conditions in catalysts and in reaction time for the reaction of protected β-D-glucosamine hydrochloride with different substituted benzaldehydes have been investigated in the presence of various inorganic and organic bases. Based on obtained results,
Prednisolone succinate-glucosamine conjugate: Synthesis, characterization and in vitro cellular uptake by kidney cell lines

, p. 25 - 28 (2012/04/04)
Prednisolone succinate-glucosamine (PSG) conjugate, a prodrug for prednisolone, was synthesized and confirmed by NMR and MS spectrum. The stabilities of the prodrug in PBS (pH 2.50, 5.00, 7.20, and 7.89) were studied. Cytotoxicity and uptake assay of the prodrug were perfomed on HK-2 and MDCK cell lines. The results showed that compared with prednisolone, the PSG not only did not increase the cytotoxicity but also improved the uptake to 2.2 times of prednisolone by the cells. Thus, it indicated that glucosamine might be a potential carrier for kidney-targeting delivery of prednisolone.

Liberek, Beata,Melcer, Anna,Osuch, Anna,Wakiec, Roland,Milewski, Slawomir,Wisniewski, Andrzej
, p. 1876 - 1884 (2007/10/03)
Mono- and di-N-alkylated derivatives of 1,3,4,6-tetra-O-acetyl-2-amino-2- deoxy-β-D-glucose (alkyl = methyl, ethyl, propyl, butyl, pentyl, hexyl, benzyl) were synthesised by the reductive alkylation of per-O-acetyl-d- glucosamine. (N-ethyl, N-propyl, N-bu
Synthetic O-glycopeptides as model substrates for glycosyltransferases
Schultz,Kunz
, p. 1205 - 1220 (2007/10/02)
A new approach to O-glycopeptides of the glucosamine type is described. N-Urethane protected, peracetylated glucosamine is converted into its 1-thio (1-bromo) derivative and used for glycosylation of a variety of protected serine or threonine derivatives
