SSTR2 Antagonist

SSTR2 Antagonists (8):

Cat. No. Product Name Effect Purity
  • HY-P1202
    CYN 154806
    		Antagonist 99.97%
    CYN 154806, a cyclic octapeptide, is a potent and selective somatostatin sst2 receptor antagonist, with pIC50 values of 8.58, 5.41, 6.07, 5.76 and 6.48 for human recombinant sst2, sst1, sst3, sst4 and sst5 receptors respectively.
  • HY-P5362
    NODAGA-LM3
    		Antagonist 99.65%
    NODAGA-LM3 is a ligand that can cross the blood-brain barrier and targets somatostatin receptor SSTR2 with high affinity (IC50 = 1.3 nM). NODAGA-LM3 does not trigger the internalization of SSTR2 and can inhibit agonist-induced internalization processes. NODAGA-LM3 shows low uptake in normal tissues such as the liver and spleen, but high uptake in the lungs and blood pool. 68Ga-labeled NODAGA-LM3 can serve as a PET imaging agent for well-differentiated neuroendocrine tumors, and is applied in studies related to small cell lung cancer and well-differentiated neuroendocrine tumors.
  • HY-P10137
    Satoreotide
    		Antagonist 98.80%
    Satoreotide (JR11) is a SSTR2 antagonist. Satoreotide is usually conjugated with radiolabeled chelators used in neuroendocrine tumor imaing.
  • HY-P11485
    JR11-PEG3-HBED-CC-PSMA-03
    		Antagonist
    JR11-PEG3-HBED-CC-PSMA-03 (Compound 1) is an RDC-related compound containing the chelating agent HBED-CC, the JR11 peptide (SSTR2 antagonist), and the PSMA ligand. JR11-PEG3-HBED-CC-PSMA-03 shows SSTR2-binding affinities and PSMA-binding affinities, with IC50 s of 59.2 nM, 57.0 nM, respectively. JR11-PEG3-HBED-CC-PSMA-03 can be radiolabeled with [68Ga]. [68Ga] radiolabeled JR11-PEG3-HBED-CC-PSMA-03 can be used in diagnostic studies of neuroendocrine differentiated prostate cancer.
  • HY-P1202A
    CYN 154806 TFA
    		Antagonist 98.30%
    CYN 154806 TFA, a cyclic octapeptide, is a potent and selective somatostatin sst2 receptor antagonist, with pIC50 values of 8.58, 5.41, 6.07, 5.76 and 6.48 for human recombinant sst2, sst1, sst3, sst4 and sst5 receptors respectively.
  • HY-P4452
    PRL 2915
    		Antagonist 99.92%
    PRL 2915 is a potent human somatostatin subtype 2 receptor (hsst2) antagonist with a Ki of 12 nM.
  • HY-P5362A
    NODAGA-LM3 TFA
    		Antagonist
    NODAGA-LM3 TFA is a ligand that can cross the blood-brain barrier and targets somatostatin receptor SSTR2 with high affinity (IC50 = 1.3 nM). NODAGA-LM3 TFA does not trigger the internalization of SSTR2 and can inhibit agonist-induced internalization processes. NODAGA-LM3 TFA shows low uptake in normal tissues such as the liver and spleen, but high uptake in the lungs and blood pool. 68Ga-labeled NODAGA-LM3 TFA can serve as a PET imaging agent for well-differentiated neuroendocrine tumors, and is applied in studies related to small cell lung cancer and well-differentiated neuroendocrine tumors.
