CYN 154806 TFA, a cyclic octapeptide, is a potent and selectivesomatostatin sst2receptor antagonist, withpIC₅₀values of 8.58, 5.41, 6.07, 5.76 and 6.48 for human recombinant sst2, sst1, sst3, sst4 and sst5 receptors respectively^[1][2].

Somatostatin Receptor^[1]

CYN 154806 TFA inhibits SRIF-induced increases in extracellular acidification (EAR) in CHO-K1 cells expressing human sst2 receptors (pKB 7.92). CYN 154806 TFA also blocks SRIF-induced increases [35S]-GTPγS binding in CHO-K1 cell membranes expressing human sst2 receptors as well as rat sst2(a) and rat sst2(b) receptors (pKB 7.81, 7.68 and 7.96, respectively)^[2].

CYN 154806 TFA (0.1 mg/kg; i.p.; 20 min before the administration of carbachol (CCh) (30 μg/kg) in M4 KO mice) dose-dependently and significantly reverses the decreases acid response to CCh in M4 but not M3 KO mice^[3].
