Aminopeptidase N (APN)/CD13 (EC 3.4.11.2) is a transmembrane protease present in a wide variety of human tissues and cell types (endothelial, epithelial, fibroblast, leukocyte). APN/CD13 expression is dysregulated in inflammatory diseases and in cancers (solid and hematologic tumors). APN/CD13 serves as a receptor for coronaviruses. Natural and synthetic inhibitors of APN activity have been characterized. These inhibitors have revealed that APN is able to modulate bioactive peptide responses (pain management, vasopressin release) and to influence immune functions and major biological events (cell proliferation, secretion, invasion, angiogenesis). Therefore, inhibition of APN/CD13 may lead to the development of anti-cancer and anti-inflammatory drugs. This review provides an update on the biological and pharmacological profiles of known natural and synthetic APN inhibitors. Current status on their potential use as therapeutic agents is discussed with regard to toxicity and specificity.
氨肽酶N(APN)/CD13(EC 3.4.11.2)是一种跨膜蛋白酶,存在于多种人体组织和细胞类型(内皮细胞、上皮细胞、成纤维细胞、白细胞)中。APN/CD13的表达在炎症性疾病和癌症(实体瘤和血液肿瘤)中失调。APN/CD13作为冠状病毒的受体。APN活性的天然和合成抑制剂已得到表征。这些抑制剂表明,APN能够调节生物活性肽反应(疼痛管理、血管加压素释放),并影响免疫功能和主要生物学事件(细胞增殖、分泌、侵袭、血管生成)。因此,抑制APN/CD13可能会导致抗癌和抗炎药物的开发。本综述提供了已知天然和合成APN抑制剂的生物学和药理学概况的最新信息。就毒性和特异性而言,讨论了它们作为治疗剂的潜在用途的现状。
