Synthesis of semitelechelic maleimide poly(PEGA) for protein conjugation by RAFT polymerization.
Biomacromolecules 10(7) , 1777-81, (2009) Maleimide end functionalized polymers for site-selective conjugation to free cysteines of proteins were synthesized using reversible addition-fragmentation chain transfer (RAFT) polymerization. A furan-protected maleimide chain transfer agent (CTA) was employ... |

Construction of highly glycosylated mucin-type glycopeptides based on microwave-assisted solid-phase syntheses and enzymatic modifications.
J. Org. Chem. 71(8) , 3051-63, (2006) A MUC1-related glycopeptide having five core-2 hexasaccharide branches (C330H527N46O207, MW = 8450.9) was synthesized by a new strategy using a combination of microwave-assisted solid-phase synthesis (MA-SPGS) and enzymatic sugar elongation. Synthesis of a ke... |

Solid-phase library synthesis, screening, and selection of tight-binding reduced peptide bond inhibitors of a recombinant Leishmania mexicana cysteine protease B.
J. Med. Chem. 45(10) , 1971-82, (2002) A one-bead-two-compound inhibitor library was synthesized by the split-mix method for the identification of inhibitors of a recombinant cysteine protease from Leishmania mexicana, CPB2.8DeltaCTE. The inhibitor library was composed of octapeptides with a centr... |

Improved biotransformations on charged PEGA supports.
Chem. Commun. (Camb.) (11) , 1296-7, (2003) PEGA supports functionalised with permanent charges show superior swelling properties in aqueous media when compared to neutral PEGA; a novel positively charged PEGA resin significantly improves penicillin G amidase (PGA) catalysed biotransformation on solid ... |

Characterization of modified alginate-poly-L-lysine microcapsules.
Artif. Organs 21(9) , 1002-6, (1997) Various modifications of alginate-poly-L-lysine microcapsules were made, such as the inclusion of polyethylenimine (PEI) or carboxyl methyl cellulose (CMC) in the core and the coating of bis(polyoxyethylene bis[amine]) (PEGA) onto the microcapsule membrane su... |

A solid-supported phosphine-free ruthenium alkylidene for olefin metathesis in methanol and water.
Bioorg. Med. Chem. Lett. 12(14) , 1873-6, (2002) The synthesis and olefin metathesis activity in protic solvents of 7, a phosphine-free ruthenium alkylidene bound to a hydrophilic solid support are reported. This heterogeneous catalyst promotes relatively efficient ring closing- and cross-metathesis reactio... |

Evaluation of resins for on-bead screening: a study of papain and chymotrypsin specificity using PEGA-bound combinatorial peptide libraries.
Bioorg. Med. Chem. Lett. 8(21) , 2997-3002, (1998) TentaGel, ArgoGel and PEGA resins were evaluated for on-bead biological screening, using a fluorescently-labelled peptide attached to each and assayed for papain activity. Peptide attached to PEGA was cleaved in near quantitative yield at the expected sites, ... |

An approach for a synthesis of asparagine-linked sialylglycopeptides having intact and homogeneous complex-type undecadisialyloligosaccharides.
Chemistry 13(2) , 613-25, (2007) This paper describes synthesis of asparagine-linked sialylglycopeptides. The typical feature of our strategy for the synthesis of a sialylglycopeptide is to employ undecadisialyloligosaccharyl Fmoc-asparagine (Fmoc-Asn(CHO)-OH) 1 without protecting groups on ... |

Interpenetrating polymer networks of alginate and polyethylene glycol for encapsulation of islets of Langerhans.
J. Microencapsul. 17(6) , 677-90, (2000) A mixture of alginate and polyethylene glycol acrylate was investigated as a system for the encapsulation of islets of Langerhans. This system showed dual crosslinkability: the alginate was ionically crosslinked by multivalent cations, and the PEG was covalen... |

Lipase-catalyzed kinetic resolution on solid-phase via a "capture and release" strategy.
J. Am. Chem. Soc. 125(46) , 13952-3, (2003) The lipase-catalyzed kinetic resolution of (R/S)-3-phenylbutyric acid 2 using solid-supported cyclohexane-1,3-dione (CHD) 6 is described. In each case the predominant enantiomer observed, after cleavage from the resin, was (R)-(-)-3-phenylbutyric acid (R)-2 (... |
