Synthetic peptides were microencapsulated into liposomes, cycled with a disulfide bond or modified with d-phenylglycine (d-phg) at the N-terminal, and their antihypertensive effects as orally administered (0.18 mM/kg body weight) to spontaneously hypertensive rats (SHR) were measured. The microencapsulated Leu-Lys-Pro reduced significantly the systolic blood pressures of SHR by 45 mmHg and showed a
将合成肽微囊化到脂质体中,在N端用二硫键循环或用d-苯基甘氨酸(d-phg)修饰,对自发性高血压大鼠(SHR)口服给予其降压作用(0.18 mM / kg体重) )进行了测量。微囊化的Leu-Lys-Pro可将SHR的收缩压显着降低45 mmHg,并显示持续时间延长,从而揭示了囊化的显着保护作用。d-phg-Leu-Arg-Pro的持续时间比未修饰的肽短约2小时。此外,在N端和C端氨基酸之间具有二硫键的环状Leu-Arg-Pro肽使SHR的收缩压降低了35 mmHg,并且显示了很长的持续时间。
