Glutamate carboxypeptidase II (GCPII), also known as prostate specific membrane antigen (PSMA), is an established prostate cancer marker and is considered a promising target for specific anticancer drug delivery. Low-molecular-weight inhibitors of GCPII are advantageous specific ligands for this purpose. However, they must be modified with a linker to enable connection of the ligand with an imaging molecule, anticancer drug, and/or nanocarrier. Here, we describe a structure-activity relationship (SAR) study of GCPII inhibitors with linkers suitable for imaging and drug delivery. Structure-assisted inhibitor design and targeting of a specific GCPII exosite resulted in a 7-fold improvement in Ki value compared to the parent structure. X-ray structural analysis of the inhibitor series led to the identification of several inhibitor binding modes. We also optimized the length of the inhibitor linker for effective attachment to a biotin-binding molecule and showed that the optimized inhibitor could be used to target nanoparticles to cells expressing GCPII.

Paragraph 0330; 0341; 0342, (2019/06/07)
The present disclosure relates to novel macrocyclic compounds and libraries thereof that are useful as research tools for drug discovery efforts. This disclosure also relates to methods of preparing these compounds and libraries and methods of using these libraries, such as in high throughput screening. In particular, these libraries are useful for evaluation of bioactivity at existing and newly identified pharmacologically relevant targets, including G protein-coupled receptors, nuclear receptors, enzymes, ion channels, transporters, transcription factors, protein-protein interactions and nucleic acid-protein interactions. As such, these libraries can be applied to the search for new pharmaceutical agents for the treatment and prevention of a range of medical conditions.
