摘要：
SRIF peptide antagonists, which are selective for SSTR2 in contrast to the other cloned SRIF receptors and which bind with high affinity to the cloned human receptor SSTR2 but do not activate the receptor, have many useful functions. Because they do not bind with significant affinity to SSTR1, SSTR3, SSTR4 or SSTR5, their administration avoids potential undesirable side effects. By incorporating radioiodine or the like in these SSTR2-selective SRIF antagonists, a labeled compound useful in drug-screening methods is provided. Alternatively, for use in therapy, highly radioactive moieties can be N-terminally coupled, complexed or chelated thereto. Because they block the receptor function, they can be used therapeutically to block certain physiological effects which SSTR2 mediates.
