8-oxoguanosine, which is derived from the oxidation of guanosine (dG), is known to induce transversion mutations (G:C→T:A) in DNA. The compounds with a small molecular weight for recognizing 8-oxoG were designed on the basis of the structure of the G-clamp, which is reported to have selective affinity toward guanosine. The G-clamp derivatives with the additional binding units toward 8-oxoG were effectively synthesized and named "8-oxoG-clamps." The 8-oxoG-clamp completely discriminated 8-oxoG from other nucleosides by fluorescence quenching.
