Cysteine-rich peptides having gamma-glutamic acid and beta-alanine units, a process for their preparation and their use

摘要

Disclosed are peptides which have the following amino acid sequence: ( gamma -Glu-Cys)n- beta -Ala n being an integer from 2 to 11; gamma -Glu represents gamma -glutamic acid; Cys represents cysteine; and beta -Ala represents beta -alanine. A process for the preparation of these peptides is disclosed as well as processes for their use for the maintenance of hemeostasis in physiological systems, the diagnosis of tumors, and the removal of heavy metals from a chemical or physiological system which has been contaminated with heavy metal.
