clinical phase are based on the Lys-Urea-Glu motif, in which Lys and Glu are α-(L)-amino acids. In this study, we aimed to determine the effect of β- and γ-amino acids in the S1 pocket on the binding affinity for PSMA. We synthesized and evaluated β- and γ-amino acid analogs with (S)- or (R)-configuration with keeping α-(L)-Glu as the S1'-binding pharmacophore. Structure-activity relationship studies identified
前列腺特异性膜抗原(PSMA)是前列腺癌进展和转移的早期诊断的极佳生物标志物。在临床阶段,最有希望的PSMA靶向药物是基于Lys-尿素-Glu基序,其中Lys和Glu是α-(L)-氨基酸。在这项研究中,我们旨在确定S1口袋中β-和γ-氨基酸对PSMA结合亲和力的影响。我们合成并评估了具有(S)-或(R)-构型的β-和γ-氨基酸类似物,并保持α-(L)-Glu作为S1'结合药效基团。结构活性关系研究确定,化合物13c(具有(R)-构型的β-氨基酸类似物)表现出最有效的PSMA抑制活性,IC50值为3.97 nM。
