Fluorescent DNA: the development of 7-deazapurine nucleoside triphosphates applicable for sequencing at the single molecule level.

7-Deaza-2'-deoxyadenosine and -guanosine phosphoramidite building blocks as well as corresponding 5'-triphosphate derivatives are described carrying in position 7 substituents such as iodo, hexyn-1-yl or 5-aminopentyn-1-yl residues. The phosphoramidites were used to synthesize a series of modified oligodeoxynucleotides. A systematic study of the thermal stabilities of these oligonucleotide duplexes demonstrated that the 7-substituents are well accommodated in the major groove of B-DNA. The 7-(aminoalkyn-1-yl)-7-deazapurine 2'-deoxynucleoside triphosphates were labeled with bulky fluorophores such as Rhodamine Green(R) or tetramethylrhodamine.[1]
