Ni and Co complexes of cross-bridged vs. unbridged tetraazamacrocycle acetate complexes reveal preferences likely to impact CXCR4 antagonist interactions.

Extending the benefits of ethylene cross-bridging to pentaazamacrocycles has been achieved and a transition metal complex prepared and structurally characterized.

Tetraazamacrocycles have been very extensively exploited as transition metal ligands for a variety of purposes, including catalysis, medical imaging, pharmaceuticals, etc. However, the pentaazamacrocycles are much less commonly used for...
