A simplified procedure for gram-scale production of sialylglycopeptide (SGP) from egg yolks and subsequent semi-synthesis of Man3GlcNAc oxazoline

Heterogeneity of glycan structures in native glycoconjugates always hampers precise studies on carbohydrate-involved biological functions. To construct homogeneous glycoconjugates from natural resource of homogeneous glycans is therefore a practical approach to solve this problem. We report here an optimized procedure for gram-scale production of sialylglycopeptide (SGP) containing a disialyl biantennary complex-type N-glycan from egg yolks. Our new procedure simplified the extraction process by treating the egg yolk powder with 40% acetone, avoiding massive emulsification, high-speed centrifugation, and sophisticated chromatography in reported methods. Subsequent semi-synthesis of the N-glycan core Man3GlcNAc oxazoline from SGP was accomplished for the first-time via glyco-trimming and successive oxazoline formation. This efficient semi-synthesis provides an alternative to the pure chemical approach that involves multi-step total synthesis and facilitates the application of endo-glycosidase-enabled chemoenzymatic synthesis of various homogeneous glycoconjugates.

Design and synthesis of aminothiazole based Hepatitis B Virus (HBV) capsid inhibitors

The capsid assembly is an essential step for Hepatitis B Virus (HBV) life cycle and is an important target for anti-HBV drug development. In this report, we identified a hit compound with aminothiazole structure by the high throughput screening (HTS) which inhibited the interaction of HBV capsid protein within the cells. The structure hopping and SAR studies of the hit compound afforded compound 79 with potent anti-HBV replication activity and good basic drug-like properties. The working mechanism studies showed that compound 79 could bind to the similar binding site of known HBV capsid inhibitor with heteroaryldihydropyrimidine (HAP) scaffold, through similar hydrophobic interactions but with a different hydrogen bond. This compound exerted potent inhibitory effect upon HBV production, either in cell culture or in mice with no obvious acute toxicity. We propose that further development of this compound could lead to novel potent anti-HBV inhibitors that target HBV capsid assembly.

Study of the diastereoselectivity of cobalt-mediated [2+2+2] cycloadditions of substituted linear enediyne esters

The preparation of substituted linear enediyne esters bearing the double bond either at the terminal or at internal position and the ester substituent either at the alkyne or at the alkene terminus is presented. Their cobalt(I)-mediated [2+2+2] cyclizations produce the eta4-complexed tricyclic compounds in very good yields. The endo/exo selectivity depends on the position of the ester in the enediyne, but the cyclization can be totally diastereoselective. The asymmetric induction in the cyclization of enediynes bearing chiral esters has been studied; however, the diastereomeric excesses are low.

Datura stramonium agglutinin: Cloning, molecular characterization and recombinant production in Arabidopsis thaliana

Datura stramonium seeds contain at least three chitin-binding isolectins [termed Datura stramonium agglutinin (DSA)] as homo- or heterodimers of A and B subunits. We isolated a cDNA encoding isolectin B (DSA-B) from an immature fruit cDNA library; this contained an open reading frame encoding 279 deduced amino acids, which was confirmed by partial sequencing of the native DSA-B peptide. The sequence consisted of: (i) a cysteine (Cys)-rich carbohydrate-binding domain composed of four conserved chitin-binding domains and (ii) an extensin-like domain of 37 residues containing four SerPro4-6 motifs that was inserted between the second and third chitin-binding domains (CBDs). Although each chitin-binding domain contained eight conserved Cys residues, only the second chitin-binding domain contained an extra Cys residue, which may participate in dimerization through inter-disulfide bridge formation. Using matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry, the molecular mass of homodimeric lectin composed of two B-subunits was determined as 68,821 Da. The molecular mass of the S-pyridilethylated B-subunit were found to be 37,748 Da and that of the de-glycosylated form was 26,491 Da, which correlated with the molecular weight estimated from the deduced sequence. Transgenic Arabidopsis plants overexpressing the dsa-b demonstrated hemagglutinating activity. Recombinant DSA-B was produced as a homodimeric glycoprotein with a similar molecular mass to that of the native form. Moreover, the N-terminus of the purified recombinant DSA-B protein was identical to that of the native DSA-B, confirming that the cloned cDNA encoded DSA-B.
