The ED50 of J-2156 in rats for the relief of mechanical allodynia and mechanical hyperalgesia in the ipsilateral hindpaws was 3.7 and 8.0 mg kg, respectively. J-2156 is a high potent, selective somatostatin receptor type 4 (SST4 receptor) agonist with IC5
CYN 154806 is a potent and selective somatostatin sst2 receptor antagonist, The pIC50 values are 8.58, 5.41, 6.07, 5.76 and 6.48 for human recombinant sst2, sst1, sst3, sst4 and sst5 receptors respectively.
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
