## Abstract N‐(2‐diethylaminoethyl)‐4‐iodobenzamide (I) and N‐(3‐dimethylaminopropyl)‐4‐iodobenzamide (II), recently developed in our laboratory, are promising agents for metastatic melanoma detection in nuclear medicine. In order to study their “in vivo” metabolism, we labelled them with carbon‐14

Abstract
O~6~ Benzyl N acetyl guanosine a new inhibitor of O~6~ Alkyl Guanine transferase (O~6~AGT) was labelled by ^14^C and ^13^C on the benzyl methylen group in order to realize a pharmacokinetic study on nude mice grafted with human tumors.
The labelling yield calculated from the precursor (Ba ^14 or 13^CO~3~) is in the range of 15%.

The ^14^C labelling of three compounds : HI‐6, TMB‐4 and pyrimidoxime is described from ^14^C‐formic acid, sodium salt. The compounds were prepared by lithiation and formylation with N‐methyl (^14^C)‐formanilide followed by introduction of the hydroxylamine moieties and alkylation of the pyridine. R
The two compounds were labelled by ^14^C on the hydroxyimino methyl group substituted on the 2 positions of the pyridinium ring. The convenient pyridinium lithiated intermediates were formylated with N‐methyl ^14^C‐formanilide. The hydroxyimino methyl groups were synthezised by reaction of the ^14^
