Abstract

Excessive production of 16beta-hydroxydehydroepiandrosterone (16beta-OH-DHEA) has been suggested as a cause of low-renin essential hypertension. The mineralocorticoid effect of 16beta-OH-DHEA was reported to be one-fortieth that of aldostereone in the rat bioassay. Using kidney slices from adrenalectomized rats, the affinity of 16beta-OH-DHEA and a series of related compounds for mineralocorticoid receptors has been determined. In studies done at both 4 C and 37 C, the affinity of 16beta-OHDHEA for mineralocorticoid receptors was found to be less than 0.1% that of aldosterone (P less than 0.01). Various related steroids and/or potential metabolites similarly showed negligible affinity for th..
