CHELATION OF METALS TO THIOL GROUPS USING IN SITU REDUCTION OF DISULFIDE-CONTAINING COMPOUNDS BY PHOSPHINES

-

Page/Page column 44-45, (2008/06/13)

A method is disclosed for the syntheses of thiol-containing radiopharmaceuticals without the need for purification starting from chelators containing disulfide bonds. This is done by providing a method that reduces disulfide bonds on a precursor molecule or a precursor compound in the presence of phosphine compounds, thus freeing thiols for metal complexation.
