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
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
