Inhibition of renin release by analogues of adenosine in rabbit renal cortical slices.

Published

Journal Article

Renal cortical slices obtained from male New Zealand rabbits were used to investigate the role of adenosine in the regulation of renin release. Isoproterenol produced a significant (p less than 0.01), twofold to threefold increase in renin release, that was both dose-dependent and time-dependent. Addition of either the l-phenylisopropyl or the N6-ethylcarboxamido derivative of adenosine attenuated this stimulation at concentrations as low as 10(-9) M or 10(-8) M, respectively. Higher doses of d-phenylisopropyladenosine (10(-6) M) or adenosine (10(-5) M) were necessary to significantly reduce the beta-adrenergic response (p less than 0.01). Inhibition was absent in slices preincubated with 10(-5) M 8-phenyltheophylline, a concentration that had no effect on either basal or stimulated renin release. The site of inhibition appeared to be distal to beta-adrenergic and prostaglandin receptors since l-phenylisopropyladenosine (10(-8) M) blocked stimulation by selective beta-adrenergic receptor agonists, prenalterol (10(-6) M) or salbutamol (10(-5) M), and by prostaglandin E1. These data suggest that adenosine and its analogues inhibit renin release and that this inhibition may be mediated by a receptor-dependent action on a common point in the pathway leading to release.
