一般描述
2,4-Difluorotoluene was synthesized as a nucleotide analog and was incorporated into DNA and undergoes replication by DNA polymerase enzymes.
应用
2,4-Difluorotoluene was used in the synthesis of new hydrophobic isosteres of pyrimidines and purine nucleosides.

A nonpolar aromatic nucleoside derivative based on 2,4-difluorotoluene (F), a non-hydrogen bonding shape analog of thymidine, was recently shown to be replicated against adenine with high efficiency and fidelity. This led to the suggestion that geometric matching, potentially even in

Certain DNA polymerases (pols) were found to efficiently insert A opposite the hydrophobic T isostere 2,4-difluorotoluene (F) and vice versa, resulting in the widely held belief that some pols rely on shape rather than H-bonding for accurate replication. Using X-ray

Recent experiments have shown that difluorotoluene (F), a nonpolar isostere for thymine (T), codes efficiently and specifically for adenine (A) in DNA replication. F has almost the same shape as thymine but it is unable to form conventional hydrogen bonds

We describe studies aimed at evaluating the physical factors governing the rate of 3'-end proofreading by the Klenow fragment of E. coli DNA polymerase I. Two nonpolar deoxynucleoside isosteres containing 2,4-difluorotoluene (F) and 4-methylbenzimidazole (Z), which are non-hydrogen-bonding shape mimics

The 2,4-difluorotoluene (DFT) analog of thymine has been used extensively to probe the relative importance of shape and hydrogen bonding for correct nucleotide insertion by DNA polymerases. As far as high fidelity (A-class) polymerases are concerned, shape is considered by
