A straightforward synthetic strategy to construct biologically relevant phenanthridinones and quinolinones was developed via visible-light-promoted direct oxidative C-H amidation. In this photocatalytic system, amidyl radicals can be generated by homolysis of the N-H bond of simple amide precursors via single-electron transfer under blue LED illumination, which leads to oxidative intramolecular C-H amidation. Moreover, an efficient synthetic strategy using a photocascade enabled facile assembly of quinolinone structures through a catalytic sequence involving triplet energy (ET) transfer-based E/Z olefin isomerization and subsequent photocatalytic generation of amidyl radical intermediates.

Method for optical measurement of multi-stranded nucleic acid using cyanine dyes
-
, (2008/06/13)
A method for optical measurement of a multi-stranded nucleic acid which comprises the step of bringing a compound into contact with a multi-stranded nucleic acid wherein said compound is capable of interacting with the multi-stranded nucleic acid, wherein the compound has the following properties:(a) the compound can exist in a substantially colorless and non-fluorescent state under at least one condition in an aqueous solution in the absence of the multi-stranded nucleic acid, and(b) when the multi-stranded nucleic acid is allowed to exist in the condition defined in the above (a), the compound changes to a substantially colored state based on an interaction with the multi-stranded nucleic acid and substantially expresses fluorescent property based on said interaction.
Substituted unsymmetrical cyanine dyes with selected permeability
-
, (2008/06/13)
The invention describes the preparation and use of fluorescent stains for nucleic acids derived from unsymmetrical cyanine dyes comprising a substituted benzazolium ring system linked by a methine bridge to a pyridinium or quinolinium ring system having at least one substituent on the pyridinium or quinolinium ring that contains a heteroatom. The presence of the heteroatom-containing substituent results in higher sensitivity to oligonucleotides and larger nucleic acid polymers in a wide range of cells and gels, and for use in analysis of cell structure, membrane integrity or function.
