The present invention involves nona- or larger bradykinin antagonist peptides characterized by the structure:
H-L-Q-T-U-V-W-X-Y-Z-Arg-OH
where certain amino acid residues of the nonapeptide hormone bradykinin or other substituted analogs of bradykinin are altered as follows: either position 2, position 3, or both consist of a L-acidic, L-amide or L-hydroxamate amino acid residue; position 7 consists of a D-aromatic amino acid residue; and position 4 preferably consists of a L-aliphatic or a D-cyclic amino acid residue.
本发明涉及非a-或更大的
缓激肽拮抗剂
多肽,其结构特征为
H-L-Q-T-U-V-W-X-Y-
Z-Arg-OH
其中,非肽激素
缓激肽或
缓激肽的其他替代类似物的某些
氨基酸残基发生了如下变化:位置2、位置3或两者均由L-酸、L-酰胺或L-羟酰胺酸
氨基酸残基组成;位置7由D-芳香族
氨基酸残基组成;位置4最好由L-脂肪族或D-环
氨基酸残基组成。
