The present invention provides cyclic tetrapeptides consisting of alternating α- and β-amino acids and metal complexes thereof. The cyclic tetrapeptides are particularly useful for coordinating a metal selected from Pb, Cd, Hg and As. Furthermore, the invention encompasses the use of the cyclic tetrapeptides in treating a disease, particularly metal poisoning, and the use in remediation of contaminated water and soil. Also methods for detecting said metals in various substrates are provided. |
