摘要:
An initiator for the terminal group of the polymer product of an atom or group radical transfer polymerisation has an activated carboxyl or an amine group which is reacted with an amine or carboxyl (respectively) group containing biologically active compound. The initiator is preferably 4-(3-(2-bromo, 2-methyl-propionate)phenyl)-propionic acid N-hydroxysuccinimide ester or 2-bromo, 2-methyl-propionic acid N-hydroxysuccinimide ester. The monomers preferably comprise a zwitterionic monomer such as 2-methacryloxyethyl-2′-trimethyl ammoniumethyl phosphate inner salt.

The present invention relates to compounds and methods for synthesizing compounds wherein the compounds exhibit extended circulating half-life in the blood. The increase in circulating half-life is achieved by conjugating polypeptides to binding groups that exhibit high affinity for human serum albumin.

摘要:
Chiral ligands and transition metal complexes based on such chiral ligands useful in asymmetric catalysis are disclosed. The chiral ligands include (R,S,S,R)-DIOP*. The ruthenium complex reduces enamide to the corresponding amine with up to 99% enantioselectivity. The transition metal complexes of the chiral ligands are useful in asymmetric reactions such as asymmetric hydrogenation, hydride transfer, hydrosilylation, hydroboration, hydrovinylation, hydroformylation, hydrocarboxylation, isomerization, allylic alkylation, cyclopropanation, Diels-Alder reaction, Heck reaction, isomerization, Aldol reaction, Michael addition and epoxidation reactions.
摘要:
The invention features linker molecules that have at one terminus a amino-protecting group and at the other terminus a phosphorous activating group, typically phosphoramidite. The linker molecules can be used, for example, to produce amino-modified linkers that space an oligonucleotide from a solid support. The invention also features an amino-protected nucleotide that includes an activated phosphorous group such as a phosphoramidite for the production of a 5null amino-modified oligonucleotide. The invention further provides a phthalimido-modified support that can be used to synthesize a polynucleotide that includes an amino group at the 3null terminus.
摘要:
Photoreactive phosphoramidites useful for attaching photoreactive sites to nucleic acids and oligonucleotides are synthesized. The resultant nucleic acid or oligonucleotide probes incorporating the photoreactive sites are then attached to a polymer-coated support by a null2null2null cycloaddition to form a microarray.
