标 题 :Synthesis of biologically active compounds in cells
发明人：SERGEEV PAVEL
权利人:SERGEEV PAVEL
摘要:This invention relates to a new method of synthesis of biologically active substances of determined structure directly in the cells of living organisms containing specific RNA or DNA molecules of determined sequence. The method is based on the hybridization of two or more oligomers bound with biologically inactive precursors of biologically active substances to specific RNA or DNA in vivo in the cells of living organisms. After hybridization of the oligomers to RNA or DNA the biologically inactive precursors bound to the 5′ and/or 3′ ends of the oligomers can interact with each other to make biologically active form of the substances. This changing of properties is due to chemical reactions which bind the biologically inactive precursors through a chemical bond into a biologically active form of the whole compound.

摘要:The present invention provides a system and method for assessing a synthetic peptide population including interrogating a population of peptide features in the presence of a receptor having an affinity for a binder sequence. The population of peptide features is synthesized over a plurality of synthesis periods and includes a plurality of control peptide features synthesized to have an amino acid sequence including the binder sequence. The control peptide features include a first feature synthesized beginning with a first one of the synthesis periods, and a second feature synthesized beginning after the first one of the synthesis periods such that synthesis of the second control peptide feature is delayed by at least one synthesis period. The method further includes detecting a signal output characteristic of an interaction of the receptor with the control peptide features, the signal output indicative of the fidelity of synthesis of the population of peptide features.

摘要:The present invention relates generally to cyclosporin analogs, and more paritcularly to methods for the solid-phase synthesis and on-resin cyclization of cyclosporin analogs. Methods are described for the on-resin cyclization of sterically hindered compounds synthesized through solid phase synthesis techniques. The methods utilize solvent, temperature, and washing conditions that allow the efficient on-resin cyclization of compounds like analogs of cyclosporin A.
