标 题 :Methods and materials for the synthesis of modified peptides
发明人：YOUNG TRAVIS G; KIESSLING LAURA L
权利人:WISCONSIN ALUMNI RES FOUND
摘要:Methods and protected amino acids useful as building blocks (protected monomers) for the synthesis of peptides and proteins that are selectively modified at one or more side-chain hydroxyl groups. Azide-bearing protecting groups allow the selective deprotection of side-chain hydroxyl groups of amino acids after synthesis of a peptide. Reaction conditions for removal of the azide-bearing protecting group can be selected which are substantially orthogonal to those that will remove α-amino protecting groups typically employed in peptide synthesis, such that hydroxyl groups protected with the azide-bearing protecting group remain protected during synthesis of the peptide chain. Various protecting groups which are readily available can be used for protecting potentially reactive side chain groups of amino acids in the peptide or protein to be modified. Preferred side-chain protecting groups are chemically distinguishable from the azide-bearing protecting group and substantially orthogonal reaction conditions can be selected such that side-chain protection of other amino acids is maintained when the azide-bearing protecting group is removed. The use of the azide-bearing protecting group of this invention for one or more hydroxy amino acids during peptide synthesis allows the selective unmasking of those azide-protected side-chain hydroxyl groups and selective modification of the hydroxyl groups that are selectively unmasked. The methods and materials herein are particularly used in synthesis of sulfated, phosphorylated and glycosylated peptides and proteins. Kits and methods of synthesizing a modified peptide or protein using the kits are also provided.

标 题 :Synthesis of photolabile 2-(2-nitrophenyl)propyloxycarbonyl protected amino acids
发明人：DELISI CHARLES P; LAURSEN RICHARD A; BHUSHAN KUMAR R
权利人:UNIV BOSTON
摘要:The 2-(2-nitrophenyl)propyloxycarbonyl (NPPOC) group has been introduced as a photolabile amino protecting group for amino acids to be used as building blocks in photolithographic solid-phase peptide synthesis. NPPOC-protected amino acids were found to be cleaved in the presence of UV light about twice as fast as the corresponding o-nitroveratryloxycarbonyl (NVOC)-protected amino acids. The protected amino acids are of particular use in the synthesis of peptide arrays.

标题:Porous wafer for segmented synthesis of biopolymers
发明人：BEATTIE KENNETH L; FROST III JAMES D
权利人:BAYLOR COLLEGE MEDICINE
摘要:A wafer for synthesizing biopolymers which includes a solid phase support material, a reaction chamber which receives and retains the support material and at least one inert porous material which allows flow through the wafer. Also included is a segmented wafer synthesis device comprising at least one, and preferably numerous, wafers for the simultaneous synthesis of multiple defined-sequenced biopolymers. Further there are process steps for synthesizing a variety of biopolymers. Synthetic polynucleotides have played a key role in studies of genetic organization through their use as primers for DNA sequencing and as hybridization probes, linkers and adapters in the cloning of genes.

标题 :Method for the synthesis of DNA sequences

摘要:A method is disclosed for the direct synthesis of double stranded DNA molecules of a variety of sizes and with any desired sequence. The DNA molecule to be synthesis is logically broken up into smaller overlapping DNA segments. A maskless microarray synthesizer is used to make a DNA microarray on a substrate in which each element or feature of the array is populated by DNA of a one of the overlapping DNA segments. The DNA segments are released from the substrate and held under conditions favoring hybridization of DNA, under which conditions the segments will spontaneously hybridize together to form the desired DNA construct. This method makes possible the remote assembly of DNA sequence, through a process analogous to facsimile transmission of documents, since the information on DNA to be made can be transmitted remotely to an instrument which can then synthesize any needed DNA sequence from the information.

摘要:The present invention relates to novel methods of synthesis of therapeutic and diagnostic dendrimers. In particular, the present invention is directed to novel dendrimer conjugates, novel methods of synthesizing the same, compositions comprising the conjugates, as well as systems and methods utilizing the conjugates (e.g., in diagnostic and/or therapeutic settings (e.g., for the delivery of therapeutics, imaging, and/or targeting agents (e.g., in disease (e.g., cancer, inflammatory disease) diagnosis and/or therapy, pain therapy, etc.)). Accordingly, dendrimer conjugates of the present invention may further comprise at least two different components for targeting, imaging, sensing, and/or providing a therapeutic or diagnostic material and/or monitoring response to therapy. Furthermore, the novel synthesis methods of certain embodiments of the present invention provide significant advantages with regard to total reaction time and simplicity.

标题 :Linkers for synthesis of oligosaccharides on solid supports
发明人：SEEBERGER PETER H; ANDRADE RODRIGO B
权利人:MASSACHUSETTS INST TECHNOLOGY
摘要:The present invention relates to versatile linkers for tethering a molecule to a solid support, e.g., for tethering a monomer, oligomer or polymer to a solid support, which are stable to a wide range of reaction conditions, but can be cleaved under well-defined conditions, thereby liberating the molecule from the solid support. Preferably, the linkers are used to tether to the solid support unprotected, partially-protected or fully-protected monosaccharides or oligosaccharides, or unprotected, partially-protected or fully-protected glycoconjugates. The linkers of the present invention may be used to tether to solid supports building blocks useful in the assembly of libraries of other types of small molecules. The present invention also relates to a molecule or plurality of molecules tethered to the solid support via a linker or linkers of the present invention. The present invention also relates to processes for synthesizing molecules, e.g., monomers, oligomers or polymers, on a solid support, wherein a starting material in the synthesis of the molecule, intermediates in the synthesis of the molecule, and the molecule itself are tethered to the solid support during the process via one of the linkers of the present invention. In certain processes of the present invention, the molecule is liberated from the solid support by cleavage of the linker of the present invention.
