Topic Novel fluorescent nucleotides for metabolic labelling

Novel nucleotides, nucleoside triphosphates and their lipophilic masked prodrugs bearing different environment-sensitive fluorescent labels will be designed and synthesized. Their enzymatic incorporations to DNA or RNA will be studied and they will be used in the construction of oligonucleotide probes for detection of interactions with biomolecules. The lipophilic prodrugs will be used in the study of their penetration to cells and applied in metabolic labelling of genomic DNA.
