+ | [[http://www.uniprot.org/uniprot/FOLH1_HUMAN FOLH1_HUMAN]] Has both folate hydrolase and N-acetylated-alpha-linked-acidic dipeptidase (NAALADase) activity. Has a preference for tri-alpha-glutamate peptides. In the intestine, required for the uptake of folate. In the brain, modulates excitatory neurotransmission through the hydrolysis of the neuropeptide, N-aceylaspartylglutamate (NAAG), thereby releasing glutamate. Isoform PSM-4 and isoform PSM-5 would appear to be physiologically irrelevant. Involved in prostate tumor progression. Also exhibits a dipeptidyl-peptidase IV type activity. In vitro, cleaves Gly-Pro-AMC. | ||

+ | Prostate-specific membrane antigen (PSMA) is an excellent biomarker for the early diagnosis of prostate cancer progression and metastasis. The most promising PSMA-targeted agents in the clinical phase are based on the Lys-urea-Glu motif, in which Lys and Glu are alpha-(l)-amino acids. In this study, we aimed to determine the effect of beta- and gamma-amino acids in the S1 pocket on the binding affinity for PSMA. We synthesized and evaluated the beta- and gamma-amino acid analogues with (S)- or (R)-configuration with keeping alpha-(l)-Glu as the S1'-binding pharmacophore. The structure-activity relationship studies identified that compound 13c, a beta-amino acid analogue with (R)-configuration, exhibited the most potent PSMA inhibitory activity with an IC50 value of 3.97 nM. The X-ray crystal structure of PSMA in complex with 13c provided a mechanistic basis for the stereochemical preference of PSMA, which can guide the development of future PSMA inhibitors. | ||
