Abstract

A multimeric MRI blood pool contrast agent based on the -borane motif is reported. Twelve copies of an amphiphilic DTPA chelate with amine end groups are appended on carbonate-functionalized -borane motif using carbamate linkages. The presence of peripheral phenyl groups on the modified DTPA chelates results in high human serum albumin binding, high relaxivity, and excellent contrast enhancement and .
