    摘要： The present invention relates to novel Pancreatic Polypeptide Family (“PPF”) polypeptides. The PPF polypeptides of the invention generally include at least two PPF motif, have at least 50% sequence identity to PYY (3-36) over its length and will generally retain, at least in part, a biological activity of a PP, PYY or NPY. Preferred PPF polypeptides of the invention are those having a potency in one of the assays described herein (preferably food intake, gastric emptying, pancreatic secretion, or weight reduction assays) which is greater than the potency of PP, NPY, PYY, or PYY(3-36) in that same assay. In one aspect, the PPF polypeptides of the invention include novel PYY analog polypeptides. In another aspect, the PPF polypeptides of the invention include PPF chimeric polypeptides including a fragment of a PP family polypeptide linked to a second PP family polypeptide, wherein each of the first and second fragments includes a PPF motif. Methods of using the PPF polypeptides of the invention, and pharmaceutical compositions including the PPF polypeptides of the invention are also disclosed.

    摘要翻译： 本发明涉及新型胰腺多肽家族（“PPF”）多肽。 本发明的PPF多肽通常包括至少两个PPF基序，其长度与PYY（3-36）具有至少50％的序列同一性，并且通常至少部分地保留PP，PYY的生物学活性或 NPY。 本发明优选的PPF多肽是在本文所述测定之一（优选食物摄取，胃排空，胰腺分泌或重量减轻试验）中具有效力的那些，其大于PP，NPY，PYY或PYY的效力（ 3-36）。 一方面，本发明的PPF多肽包括新的PYY类似物多肽。 在另一方面，本发明的PPF多肽包括PPF嵌合多肽，其包括与第二PP家族多肽连接的PP家族多肽的片段，其中第一和第二片段中的每一个包括PPF基序。 还公开了使用本发明的PPF多肽的方法和包括本发明的PPF多肽的药物组合物。
