Abstract
Atriopeptin III (AP III) and its six analogues were synthesized by solid phase method and their diuretic and hypotensive activities were determined. Among these analogues, analogue [D-Ala-5, D-Arg-23] AP III was nearly 10 times as potent as AP III in diuretic activity while its hypotensive activity increased only 50% of that of AP III. Analogue des [Ser-15Gly-16Leu-17Gly-18Asn-20Ser-21] AP III was 15% as potent as AP III in diuretic activity, but it still maintained about 60% of the hypotensive activity of AP III. Meanwhile, we tried analogue [D-Ala-5, D-Agr-23] AP III for the treatment of hypertensive syndrome in pregnancy and obtained some good results.
