Muellar, Stefan published the artcile8-Vinylguanine Nucleo Amino Acid: A Fluorescent PNA Building Block, Recommanded Product: 2-(N-(2-((((9H-Fluoren-9-yl)methoxy)carbonyl)amino)ethyl)-2-(5-methyl-2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)acetamido)acetic acid, the publication is Organic Letters (2012), 14(6), 1382-1385, database is CAplus and MEDLINE.
Attachment of a vinyl group at guanine position 8 provides fluorescent properties of the nucleobase. Therefore, 8-vinylguanine was introduced as a 2-aminoethylglycine peptide nucleic acid (PNA) building block. Incorporation of the guanine analog in short PNA sequences by Fmoc solid phase peptide synthesis allowed the differentiation between hybridization states of specific double strands with DNA, RNA, and PNA as well as quadruplex forming RNA/PNA oligomers based on fluorescence intensity.
