Efficient synthesis of 3-cyanovinylcarbazole-1′-β-deoxyriboside-5′-triphosphate: a reversible photo-cross-linking probe
摘要:
We describe an efficient synthesis of 3-cyanovinylcarbazole-1'-beta-deoxyriboside-5'-triphosphate containing light-responsive artificial nucleobase 3-cyanovinylcarbazole, which can be used as a reversible photo-cross-linking probe with nucleic acid compounds for various biological applications. A three-step synthesis of 3-cyanovinylcarbazole-1'-beta-deoxyriboside starting from 3-cyanovinylcarbazole, followed by 'one-pot, three-step' procedure is presented to accomplish the title compound 3-cyanovinylcarbazole-1'-beta-deoxyriboside-5'-triphosphate in good yields.

Ultrafast Reversible Photo-Cross-Linking Reaction: Toward in Situ DNA Manipulation
摘要:
We describe a novel ultrafast reversible DNA interstrand photo-cross-linking reaction via 3-cyanovinylcarbazole nucleoside ((CNV)K). Oligodeoxynucleotide (ODN) containing (CNV)K can be photo-cross-linked by irradiation at 366 nm for 1s, and the photo-cross-linked ODN can be split by irradiation at 312 nm for 60 s.
