As an important step of the active demethylation of 5-methylcytosine (5mC), human thymine DNA glycosylase (hTDG) efficiently excises 5-carboxylcytosine (5caC) from double-stranded DNA (dsDNA). Here, we present synthesis of DNA oligos containing a 2′-deoxy-2′-fluoro-d-arabinofuranosyl-5- carboxylcytidine (F-5caC) modification that act as hTDG inhibitors. The glycosylase activity assay showed that F-5caC oligos were resistant to excision by the hTDG catalytic domain (hTDGcat, residues 111-308) and they could inhibit the excision of DNA oligos containing 5caC. The electrophoretic mobility shift assay confirmed that DNA oligos containing F-5caC could bind well with unmodified hTDGcat to form a stable complex, which makes it possible to obtain the crystal structure of the complex to reveal details on how hTDGcat recognizes the DNA substrate.

The syntheses of several 2'-halogeno-5-substituted-arabinofuranosylcytosines and -uracils are described, and relationships of structure to anti herpes virus activity in vitro were examined.Those arabinonucleosides containing the 2'-fluoro function exhibit
