Methylglyoxal (MGO) is a reactive dicarbonyl metabolite that modifies histones in vivo and induces changes in chromatinstructure and function. Here we report the synthesis and application of a chemicalprobe for investigating MGO-glycation. A two-step synthesis of a Cu-click compatible alkynyl oxoaldehyde probe (AlkMGO) via sequential Dess-Martin and Riley oxidations is presented. This synthesis elevates the

The present invention provides a method for detecting the presence or absence of a guanine-abasic site, the method being a process for detecting guanine opposite at least one abasic sites generated in a double-stranded DNA, comprising:
(1) step 1 of site-selectively cleaving at least one abasic sites in a double-stranded DNA using an enzyme;
(2) step 2 of modifying the amino group at position 2 of guanine opposite the abasic sites using a modifier; and
(3) step 3 of performing polymerase chain reaction on the modified double-stranded DNA obtained by conducting step 1 and step 2, which serves as a template, to search for the presence or absence of an amplification product, the sequence of steps 1 and 2 being not limited to the order presented.

Development of a chemical probe for identifying protein targets of α-oxoaldehydes
The development of a chemical probe for identifying the protein targets of reactive electrophilic α-oxoaldehydes such as methylglyoxal is presented. The probe is evaluated against methylglyoxal using human serum albumin as well as using living cells and lysates.
