Chelate derivatives of atrial natriuretic factor (ANF)

摘要

Derivatives of synthetic fragments of mammalian atrial natriuretic factor (ANF) in which a chelate molecule is attached to the N- terminal of the peptide are described. The chelate component allows the facile labelling of these peptides with metallic isotopes such as Tc-99m, Ga-67, In-111 and others. These radioactive chelates are useful in determining the in vivo behavior and fate of derivatives of ANF.
