摘要:
The present invention is directed to new cationic lipids and intermediates in their synthesis that are useful for transfecting nucleic acids or peptides into prokaryotic or eukaryotic cells. The lipids comprise one or two substituted arginine, lysine or ornithine residues, or derivatives thereof, linked to a lipophilic moiety. The lipids form a complex when mixed with polyanions such as nucleic acids or peptides. The complexes permit efficient transfer of polyanions into cells, usually without significant toxicity to the cells.
摘要:
The present invention is directed to improved methods to synthesize oligonucleotide analogs having an acetal linkage, such as a 3',5'-formacetal (3' --O--CH.sub.2 --O-- 5'), 3',5'-thioformacetal (3' --S--CH.sub.2 --O-- 5') or an analogous 2',5' linkage between adjacent nucleoside analog residues. Compositions comprising 5', 3' and 2' phosphinate nucleoside analogs useful in the methods are also provided.
摘要:
Oligonucleotide analogs having one or more substitute linkages of the formula 2'/3'--S--CH.sub.2 --CH.dbd.5' or 2'/3'--O--CH.sub.2 --CH.dbd.5' between adjacent nucleomonomers are disclosed. The substitute linkage replace the usual phosphodiester linkage found in unmodified nucleic acids. The oligonucleotide analogs are easy to synthesize, stable in vivo, resistant to endogenous nucleases and are able to hybridize to target nucleic acid sequences in a sequence specific manner.
摘要:
A method is provided for the high fidelity, rapid and economical in vitro synthesis of oligonucleotides. Nucleoside H-phosphonates are condensed in seriatim using a dehydrating agent to produce a poly (nucleoside H-phosphonate). The produce is oxidized to yield the desired oligonucleotide. A novel reagent is provided for multiple nucleoside additions in single cycles.
摘要:
The present invention provides 2-aminopyridine and 2-pyridone C-nucleosides and oligonucleotides containing the subject nucleosides. The nucleosides are useful in the preparation of the subject oligonucleotides. The oligonucleotides are useful in oligonucleotide-based diagnosis and separation through triplex binding.

摘要:
This invention is a process for the production of oligonucleotides which comprises:(a) converting an inorganic polymer into a coupling agent-polymer;(b) combining the coupling agent-polymer with a blocked nucleoside to obtain a blocked nucleoside-modified support; and(c) removing the blocking group from the blocked nucleoside-modified support to provide for the coupling of nucleotides to the nucleoside-modified support.
