PSMA

Prostate-specific membrane antigen

PSMA is a transmembrane protein that anchores to the cell membrane through its transmembrane region and is mainly expressed in prostate epithelial cells but also exists in other tissues. PSMA exhibits glutamate-preferring carboxypeptidase activity that hydrolyzes polyglutamylated folic acid to release folic acid monomers. PSMA mediates the endocytosis on the cell surface. PSMA acts as an angiogenesis marker in cancer cells. PSMA can be used as a diagnostic marker for prostate cancer, and for detection of invasiveness and metastatic ability of the tumor[1].

    HYNIC-iPSMA
    HYNIC-iPSMA is a ligand for molecular imaging of tumors. Hynic-ipsma consists of two components: HYNIC (6-hydrazinonicotinamide) and iPSMA (Inhibitor of Prostate-Specific Membrane Antigen). HYNIC is a compound used to attach radioactive isotopes to targeted molecules. iPSMA is a specific inhibitor used to inhibit prostate-specific membrane antigen (PSMA). 68GA-labeled iPSMA has been used to detect prostate cancer by PET imaging. The further 99mTc-EDDA/HYNIC-iPSMA has excellent specificity and sensitivity. HYNIC-iPSMA can be used for the synthesis/research of Radionuclide-Drug Conjugates (RDCs).

    PSMA-IN-3
    		Inhibitor
    PSMA-IN-3 (compound 17) is a novel high-affinity PSMA inhibitor with an IC50 value of 13 nM. PSMA-IN-3 is suitable for developing an 18F-labeled radioligand for PET imaging of PSMA in prostate cancer.

    DCFBC
    		Inhibitor
    DCFBC is a prostate-specific membrane antigen (PSMA) inhibitor that can be used for small animal positron emission tomography (PET) imaging. DCFBC labeled with F18 ([18F]DCFBC) can images in severe combined immunodeficient mice. [18F]DCFBC uptake is higher in PIP tumors, but almost absent in FLU tumors. [18F]DCFBC uptake is also high in the kidney and bladder, but the radioactivity washout time is shorter than that in PIP tumors. Indicating that [18F]DCFBC can specifically localize to PSMA+ expressing tumors and is applicable to the study of prostate cancer.

    NH2-NODAGA
    NH2-NODAGA is a NODAGA-type metal chelator that can bind to radionuclides to prepare radionuclide conjugates (RDCs). NH2-NODAGA can react with diethyl squarate in 0.5M phosphate buffer (room temperature, 2 h, pH 7-7.5) to obtain NODAGA.SA. NODAGA.SA can target L-lysine urea-L-glutamate (KuE), which is a key structure of prostate-specific membrane antigen (PSMA). NODAGA.SA.KuE can bind [68]Ga and can be used for PET examination of NMRInu/nu nude mice bearing LNCaP tumors.
