Cell density cultivation of recombinant Escherichia coli strains harboring the nodC gene (encoding chitooligosaccharide synthase) from Azorhizobium caulinodans has been previously described as a practical method for the preparation of gram-scale quantities of penta-N-acetyl-chitopentaose. We have now extended this method to the production of allylated derivative of penta-N-acetyl-chitopentaose by using allyl 2-acetamido-2-deoxy-beta-d- glucopyranoside (2) as the initial acceptor for the synthesis of target pentaoside in vivo.

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.

The development of sialidase inhibitors is an area of continuing interest due to their potential use as therapeutic agents to combat viral and bacterial infections. Herein, we report our studies involving the sialidase from the pathogen Vibrio cholerae, through the modelling, synthesis and biological evaluation of mimetics of 5-acetamido-2,6-anhydro-3,5-dideoxy-d-glycero-d- galacto-non-2-enonic acid (Neu5Ac2en, 1), a naturally occurring sialidase inhibitor. These mimetics are O- and S-glycosides of N-acetyl-d-glucosaminuronic acid in which the aglycone portion effectively replaces the C-6 glycerol side chain of Neu5Ac2en (1). The choice of aglycones was aided by use of the X-ray crystal structure of V. cholerae sialidase complexed with Neu5Ac2en (1). All Neu5Ac2en mimetics tested were found to inhibit V. cholerae sialidase as determined using a standard fluorometric assay.

Porphyromonas gingivalis (P.g.)-induced TNF-alpha can be affected by muramyl dipeptide (MDP) in a biphasic concentration-dependent manner. We found that in P.g.-exposed macrophages, treatment with 10 mug/mL of MDP (MDP-low) up-regulated TNF-alpha by 29%, while 100 mug/mL or higher (MDP-high) significantly decreased it (16% to 38%). MDP-high was found to affect the ubiquitin-editing enzyme A20 and activator protein 1 (AP1). An AP1 binding site was found in the promoter region of A20. A20 promoter activity was up-regulated after transfection of AP1 cDNA in cells. Four analogues of MDP (3-6) were prepared through a convergent strategy involving the synthesis of two unique carbohydrate fragments, 7a and 7b, using the peptide coupling reagents, EDCI and HOAt. Analogue 4 improved MDP function and P.g.-induced activities. We propose a new signaling pathway for TNF-alpha induction activated after exposing macrophages to both P.g. and MDP-high or analogue 4.

Octa-substituted phthalocyanines carrying either one or two hydroxyalkyl chains have been synthesized and their liquid crystalline behaviour characterised by polarised light microscopy and differential scanning calorimetry. The compounds form discotic columnar mesophases with hexagonal or rectangular symmetry. Examples have been used as precursors for the synthesis of mesogenic di-nuclear and tri-nuclear phthalocyanines, ie derivatives containing two or three phthalocyanine rings. These compounds have been characterised by elemental analysis and low resolution field desorption mass spectrometry, FD-MS. 1H NMR spectroscopy and gel permeation chromatography of selected examples provide supporting data. Visible region spectroscopy of dilute solutions of the multinuclear phthalocyanines in cyclohexane (down to a concentration of 5 x 10-7 mol dm-3 where intermolecular aggregation is expected to be minimal) suggests that the compounds exist as an equilibrium between a ‘closed’ conformer where the two rings are arranged cofacially (broad band centred at ca 645 nm) and an open form having an absorption band similar to that of the simpler precursor phthalocyanines, lambda(max) ca. 730 nm. The closed conformer is favoured in more polar media eg 10% toluene – 90% ethanol. Examples have been deposited as spin coated films of even thickness on glass slides.
