Synthesis of Novel Citrate-Based Siderophores and Siderophore-β-Lactam Conjugates. Iron Transport-Mediated Drug Delivery Systems

Ghosh, Arun,Miller, Marvin J.

, p. 7652 - 7659 (2007/10/02)

The synthesis of analogs of arthrobactin (5), a microbial iron chelator, and its imide 8 are described.The differentially protected citric acid residue 31 served as the key intermediate in making conjugates having a generalized structure 14 with two representative carbacephalosporin units, 15 and 16.Both conjugates, 49 and 51, showed antibiotic activity, while conjugate 51 obtained from β-lactam 16 bearing a phenylglycyl side chain was shown to be more effective.
