Configurationally restricted bismacrocyclic CXCR4 receptor antagonists.

A zinc(II) containing configurationally restricted analogue of bismacrocyclic cyclam-type CXCR4 chemokine receptor antagonists has been synthesized and shown to adopt only one configuration in solution. The single crystal X-ray structure reveals favorable binding to acetate via a bidentate chelation that can be related to the proposed interaction with aspartate on the receptor protein surface. ...

Protein recognition of macrocycles: binding of anti-HIV metallocyclams to lysozyme.

The macrocyclic antiviral drug xylyl-bicyclam blocks entry of HIV into cells by targeting the CXCR4 coreceptor, a seven-helix transmembrane G-protein-coupled receptor. Its affinity for CXCR4 is enhanced by binding to Cu2+, Ni2+, or Zn2+. Metallocyclams have a rich configurational chemistry and proteins may bind selectively to specific metallocyclam configurations. Our studies of lysozyme reveal...

CXCR4 chemokine receptor antagonists: nickel(II) complexes of configurationally restricted macrocycles.

Tetraazamacrocyclic complexes of transition metals provide useful units for incorporating multiple coordination interactions into a single protein binding molecule. They can be designed with available sites for protein interactions via donor atom-containing amino acid side chains or labile ligands, such as H(2)O, allowing facile exchange. Three configurationally restricted nickel(II) cyclam com...

Binding optimization through coordination chemistry: CXCR4 chemokine receptor antagonists from ultrarigid metal complexes.

A new copper(II) containing bis-macrocyclic CXCR4 chemokine receptor antagonist is shown to have improved binding properties to the receptor protein in comparison to the drug AMD3100 (Plerixafor, Mozobil). The interaction of the metallodrug has been optimized by using ultrarigid chelator units that offer an equatorial site for coordination to the amino acid side chains of the protein. Binding c...
