Application Of Coumarin Derivatives In Dna-Associated Study: Mutation Detection, Site-Specific Labeling, Photoinduced Interstrand Cross-Links And Ligation Reactions, Huabing Sun
Theses and Dissertations
Coumarin derivatives have been widely utilized as cross-linking agents in polymer science, being fluoroprobes in biochemistry and as medicines in pharmacy. But the coumarin's fluorogenic properties and reactivities in DNA were rarely reported and unclear, which limits its bioapplications due to possible side reactions towards biomolecules. In this thesis, we investigated the activity of coumarin moiety towards natural DNA and expanded its application in DNA-associated study. We have found that coumarin derivatives can serve as perfect DNA cross-linking agents, as alkylation agents for site-specific labeling, and fluoroprobes for single nucleotide polymorphism (SNP) analysis, which provided a novel insight of biotoxicity …
