    • Analogs of SRIF which are selective for SSTR4 in contrast to the other cloned SRIF receptors are useful in determining tissue and cellular expression of the receptor SSTR4 and its biological role in regulating tumor growth. SRIF analog peptides, such as des-AA 1,2,4,5,12,13 [Ala 7 ] -SRIF; des­-AA 1,2,4,5,12,13 [Aph 7 ] -SRIF, des-AA 1'2,4,5,12,13 [Aph 7 ] Cbm-SRIF; des­AA 1,4,5,12,13 [Tyr 2 Ala 7 ] -Cbm-SRIF, and des-AA 1'2,4,5,12,13 [Tyr 7 , C B Me-L­2Nal 8 ]-SRIF, and counterparts incorporating D-Cys 3 and/or D­Trp 8 and/or Ala 11 , bind with high affinity to the cloned human receptor SSTR4 and activate the receptor, but they do not bind with significant affinity to human SSTR1, SSTR2, SSTR3 or SSTR5. By incorporating an iodinated tyrosine in position-2 in these SSTR4-selective SRIF analogs, a labeled compound useful in drug-screening methods is provided. Alternatively, for use in therapy, cytotoxins or highly radioactive elements can be N-terminally coupled or complexed thereto.
    • 与其他克隆的SRIF受体相比,选择性SSTR4的SRIF的类似物可用于确定受体SSTR4的组织和细胞表达及其在调节肿瘤生长中的生物学作用。 SRIF类似物肽,如des-AA <1,2,4,5,12,13> [Ala 7] -SRIF; des-AA <1,2,4,5,12,13> [Aph 7] -SRIF,des-AA <1,2,4,5,12,13> [Aph 7] Cbm-SRIF ; desAA <1,4,5,12,13> [Tyr 2 Ala 7] -C bm-SRIF和des-AA <1,2,4,5,12,13> [Tyr 7] 结合D-Cys 3和/或DTrp 8和/或Ala 11的对应物以高亲和力结合到克隆的人受体SSTR4并激活 受体,但它们不以与人SSTR1,SSTR2,SSTR3或SSTR5的显着亲和力结合。 通过在这些SSTR4选择性SRIF类似物中加入位置2的碘化酪氨酸,可以提供用于药物筛选方法的标记化合物。 或者,为了用于治疗,细胞毒素或高度放射性元素可以是N-末端偶联或与其复合的。
