An improved synthesis of hexafluorovaline (Hfv) derivatives, i.e., DL-Hfv-OBzl and Boc-DL-Hfv, is described. Incorporation of hexafluorovaline into angiotensin resulted in [Sar1,Hfv8]AII and [Sar1,D-Hfv8]AII. At the nanogram/milliliter dose range, the L congener was 20-100 times more active as either angiotensin agonist or angiotensin antagonist than its D diastereomer on isolated tissue preparations
描述了六氟缬氨酸(Hfv)衍生物,即DL-Hfv-OBzl和Boc-DL-Hfv的改进的合成。将六氟缬氨酸掺入血管紧张素中可产生[Sar1,Hfv8] AII和[Sar1,D-Hfv8] AII。在纳克/毫升的剂量范围内,L同类药物在分离的组织制剂中,其血管紧张素激动剂或血管紧张素拮抗剂的活性比其D非对映异构体高20-100倍。在微克剂量范围内,[Sar1,Hfv8] AII和[Sar1,D-Hfv8] AII均比[Sar1,Leu8] AII作为血管紧张素II抑制剂更有效,从而长时间抑制了对血管紧张素II的升压反应1小时
