mini atrial natriuretic polypeptide, which has an important turnlike conformation at Gly(6)-Arg(7)()-Met(8)-Asp(9). Structural analysis revealed that the size of the conformational space of Arg(7) on binding to the receptor was approximately one-third of the entire conformational space.
化合物(2S,4S)-和(2S,4R)-4-(2'-胍基乙基)脯氨酸已合成为构象受限的精氨酸。它们的主链轮流适合i +1位置,与精氨酸相比,侧链受到限制。这些类似物被纳入到微型心房利钠多肽中,该多肽在Gly(6)-Arg(7)()-Met(8)-Asp(9)处具有重要的轮状构象。结构分析表明,Arg(7)与受体结合时构象空间的大小约为整个构象空间的三分之一。
