Labeling Methods with Oxygen Isotopes |
| abstract |
The present invention provides methods for labeling One or two oxygen atom(s) in a carboxyl group of a carboxyl-containing compound with an oxygen isotope selected from oxygen-17 ( 17 O) or oxygen-18 ( 18 O). The methods of the present invention are characterized in that an activated ester of the carboxyl-containing compound (carboxylic acid) is reacted with H 2 17 O or H 2 18 O in the presence of an activator. In the methods of the present invention, the reaction between the activated ester of a carboxylic acid and H 2 17 O or H 2 18 O can be allowed to proceed without including drastic conditions such as strongly acidic conditions or alkaline hydrolysis because an activator is used. |
