Treatment and/or prophylaxis of hypertension involving administering a therapeutically active amount of an edg-receptor agonist or a pharmaceutically acceptable salt thereof. Preferably the edg-receptor agonist is a highly selective I
1
-receptor agonist and essentially devoid of α
2
-receptor agonist activity and has an imidazoline structure. Hence, hypertension may be treated without causing α
2
-receptor induced side effects. The invention also provides appropriate screening tools for identifying compounds acting with high selectivity as I
1
-receptor agonists however lacking α
2
-receptor induced side effects. Furthermore, the receptor, membranes and cells comprising said receptor, and assays for screening compounds with said receptor are discussed in the context of the invention.
治疗和/或预防高血压,包括施用治疗活性量的edg-受体激动剂或其药学上可接受的盐。最好是高选择性的 I
1
-受体激动剂,并且基本上不含 α
2
-受体激动剂活性,并具有
咪唑啉结构。因此,在治疗高血压时不会引起α 2 -受体激动剂的活性。
2
-受体引起的副作用。本发明还提供了适当的筛选工具,用于鉴定具有高选择性 I
1
-受体激动剂但缺乏 α
2
-受体诱导的副作用。此外,本发明还讨论了受体、包含所述受体的膜和细胞,以及用所述受体筛选化合物的检测方法。
