sstr

Cyclic SSTR agonist octreotide is a Octreotide , serving as the cyclic Somatostatin Receptor SSTR agonist [1] .

Pasireotide Acetate is a stable cyclohexapeptide somatostatin mimic

Potent somatostatin receptor 1 (sst1) agonist; displays selectivity for sst1 (IC50 values are 30.9 nM, 345 nM, > 1 μM, > 10 μM and > 10μM for human sst1, sst3, sst4, sst2 and sst5 respectively). Attenuates somatostatin release in the rat nucleus accumbens

DOTA-LM3 is a somatostatin receptor (SSTR) antagonist, with LM3 denoting the peptide sequence p-Cl-Phe-cyclo(D-Cys-Tyr-D-4-amino-Phe(carbamoyl)-Lys-Thr-Cys)D-Tyr-NH2. It is utilized in the isotopic labeling of tumors for in vivo tracing, notably with 177Lu-DOTA-LM3 and 68Ga-DOTA-LM3. The derivative 68Ga-DOTA-LM3 exhibits promising biodistribution, high tumor uptake, efficient tumor retention, and minimal safety concerns, while 177Lu-DOTA-LM3 is applied in research on DOTATOC-negative liver metastases including pancreatic NET and extensive tumor thrombosis [1] [2].

NODAGA-LM3 TFA, a SSTR2 antagonist, can be radiolabeled with ^68Ga for PET imaging applications, particularly in the visualization of SSTR-positive paragangliomas [1] [2].

Octreotide (SMS 201-995) is a potent inhibitor of growth hormone, glucagon, and insulin.

NODAGA-LM3, when labeled with ^68Ga, serves as a PET imaging agent. As an SSTR2 antagonist, ^68Ga-NODAGA-LM3 is utilized for the visualization of SSTR-positive paragangliomas [1] [2].

Octreotide Acetate (Sandostatin) is a potent, long-acting synthetic somatostatin octapeptide analog that inhibits secretion of growth hormone.
