AEC抑制剂已应用于临床治疗高血压和充血性心力衰竭，传统的ACE抑制剂是二肽或氨基酸的衍生物，在结构上本品不同于传统的ACE抑制剂，它不含有环状氨基酸如脯氨酸，即异羟后非氨基酸衍生物，其锌结合配位体是异羟后基而不是流基。由于结构的原因，异羟胯丙脯酸几乎与流甲丙脯氨 AEC inhibitors have been used in clinical treatment of hypertension and congestive heart failure, the traditional ACE inhibitors are dipeptide or amino acid derivatives, structurally different from the traditional ACE inhibitors, it does not contain cyclic amino acids such as Proline, a non-amino acid derivative of oxyhydroxyl, whose zinc-binding ligand is a hydrogeroxyl instead of a flow group. Due to structural reasons, hydroxyproline is almost bound to streptozotocin
