Unnatural multidentate metal ligating α-amino acids
摘要:
A family of penta- and hexadentate metal ligating alpha-amino acids, suitably protected for Fmoc solid-phase chemistry, has been prepared. These residues incorporate the mono-amides of ethanolaminetriacetic acid, ethylenediaminetriacetic acid, and ethylenediaminetetraacetic acid as side chains. Side chains are tethered varying distances (n) from the C alpha-carbon to allow metal binding events to occur at distinct distances from the peptide backbone. These residues are designed to allow the facile installation of metal chelates along a peptide backbone. (c) 2006 Elsevier Ltd. All rights reserved.

A chelator having the general structure (I) wherein each R1 is independently OH, NH or SH, and X is O, S, or NR3, wherein R3 is H or CH2C(=O)R1. Methods of making and using the chelator, metal chelates, and biological constructs for delivering targeted radiation therapy using the chelator are provided. (I).
isomeric species by nuclear magnetic resonance and density functional theory. Metal binding versatility demonstrated in radiolabeling [111In]In3+, [155Tb]Tb3+, [177Lu]Lu3+, and [225Ac]Ac3+ achieved high molar activities under mild conditions. Efficient, scalable synthesis enabled in vivo evaluation of bifunctional H4noneunpaX conjugated to two octreotate peptides targeting neuroendocrine tumors. Single photon
