Carboxymethyl-substituted bifunctional chelators: preparation of aryl isothiocyanate derivatives of 3-(carboxymethyl)-3-azapentanedioic acid, 3,12-bis(carboxymethyl)-6,9-dioxa-3,12-diazatetradecanedioic++ + acid, and 1,4,7,10-tetraazacyclododecane-N,N',N",N'''-tetraacetic acid for use as protein labels.

3-(Carboxymethyl)-3-azapentanedioic acid (NTA), 3,12-bis(carboxymethyl)-6,9-dioxa-3,12-diazatetradecanedioic acid (EGTA), and 1,4,7,10-tetraazacyclododecane-N,N',N",N'''-tetraacetic acid (DOTA) structures having a 4-nitrophenyl substituent attached via an alkyl spacer to the methylene carbon atom of one carboxymethyl arm of the chelator were obtained by alkylation of 4-nitrophenylalanine with bromoacetic acid (NTA), by reductive alkylation of 1,8-diamino-3,6-dioxaoctane with (4-nitrophenyl)-pyruvic acid followed by alkylation with bromoacetic acid (EGTA), and by alkylation of the trimethyl ester of 1,4,7,10-tetraazacyclododecane-N,N',N"-triacetic acid with the methyl ester of alpha-bromo-4-(4-nitrophenyl)pentanoic acid and subsequent saponification (DOTA). The nitrophenyl-substituted chelators were converted to the corresponding amines by hydrogenation then reacted with thiophosgene to give the protein-reactive aryl isothiocyanate derivatives.[1]
