[Comparative pharmacological characteristics of peptides of the atrial natriuretic factor family].
Comparative antihypertensive and natriuretic activities of atrial natriuretic factor (ANF) and its nearest shortened analogues--atriopeptines (AP) were studied in vivo on narcotized rats; and their peripheral vasodilating activities were studied in vitro on isolated rings of rat's thoracic aorta. The results obtained in vivo allow a following series of comparative antihypertensive and vasodilating activity: alpha rANF greater than APII greater than AP7-27. alpha rANF, APIII and APII did not differ significantly in vasodilating activity on isolated vessels; analogue 7-27 was less active. Thus further search of highly active shortened atriopeptin analogues is necessary for developing new drugs on their basis.
