Synthesis and initial in vitro evaluation of PSMA-targeted ligands with optimized structural motifs.

Abstract

An improved series of ligands targeting prostatic specific membrane antigen (PSMA) has been reported. Varying compounds and their biological parameters were due to changes in the linker structure. Highly selective compounds with nanomolar IC50 values were obtained. As an example, a conjugate with Sulfo-Cy5 and MMAE was obtained and pre-studied.
