专利号:US-9512250-B2 优先权日:2012-02-23 标 题 :Manganese catalyzed photopolymerization of fluorinated monomers 发明人:ASANDEI ALEXANDRU D 权利人:UNIV CONNECTICUT 摘要:The disclosure discloses initiating systems for the radical polymerization of alkenes, and especially fluorine substituted alkenes. The polymerization is catalyzed by a metal carbonyl, preferably manganese carbonyl. The polymerization is initiated directly from alkyl halides at room temperature under visible white light. The polymers also allow the synthesis of block copolymers. The process comprises polymerizing at least one alkene monomer in the presence of a halide radical initiator, carbonyl catalyst and a solvent, under reaction conditions and for a time sufficient to polymerize the at least one alkene monomer to form a polymer. The present disclosure provides a method for living polymerization of alkene monomers which provides a high level of macromolecular control over the polymerization process and which leads to uniform and controllable polymeric products. This disclosure also provides a method for activating any halide (Cl, Br, I) chain ends of such polymers for the synthesis of block copolymerizations.
专利号:US-9346851-B2 优先权日:2008-02-22 标 题 :Chemical modification of proteins 发明人:BERNARDES GONCALO; CHALKER JUSTIN; DAVIS BENJAMIN 权利人:BERNARDES GONCALO; CHALKER JUSTIN; DAVIS BENJAMIN; RP SCHERER TECHNOLOGIES LLC 摘要:The invention relates to methods for selectively converting a cysteine residue in a peptide or protein to the dehydroalanine (Dha) residue. The method also works on selenocysteine and substituted cysteine and selenocysteine residues, resulting in the Dha residue which may be converted to any natural or unnatural amino acid residue desired without the alteration of the remainder of the peptide or protein. The invention also allows ligation of a desired peptide at any point rather than at a point where there should be a naturally occurring cysteine, thereby allowing native chemical ligation to be used in the synthesis of peptides that do not contain cysteine. The methodology allows for the synthesis of very large peptides.
