The two forms (DTyr8 and LTyr8) of the putative somatostatin sst2 receptor antagonist CYN 154806 (Ac-4NO2-Phe-c(DCys-Tyr-DTrp-Lys-Thr-Cys)-D/LTyr-NH2) were investigated on recombinant human somatostatin receptors and endogenous guinea-pig ileum receptors. In radioligand binding studies using the agonist radioligands [125I]LTT-SRIF-28, [125I][Tyr10]cortistatin-14, [125I]CGP 23996

In the mammalian retina, somatostatin (SRIF-14) acts through distinct receptor subtypes (sst(1-5)). Among them, sst(2) has been localized to numerous retinal cells, including photoreceptors and rod bipolar cells (RBCs). The specific role of sst(2) in the retina is largely undetermined.

Somatostatin (SRIF, somatotropin release inhibiting factor), discovered for its inhibitory action on growth hormone (GH) secretion from pituitary, is an abundant neuropeptide. Two forms, SRIF14 and SRIF28 exist. Recently, a second family of peptides with very similar sequences and features
