Toxicity Profile

Route of Exposure

Not Available

Mechanism of Toxicity

18-Hydroxycorticosterone is a derivative of corticosterone. It serves as an intermediate in the synthesis of aldosterone by the enzyme aldosterone synthase in the zona glomerulosa. (Wikipedia) 18-Hydroxycorticosterone (18OHB) has low affinity for the mineralocorticoid receptor and mainly originates from the conversion of corticosterone by the aldosterone synthase, although small amounts may be produced by the 11β-hydroxylase. Serum concentrations of 18OHB increase with increased aldosterone synthesis due to sodium depletion and angiotensin II infusion. (7) Accumulation of 18-hydroxycorticosterone in a given organ has been shown to be toxic for the body.

Minimum Risk Level

Not Available

Health Effects

Chronically high levels of 18-hydroxycorticosterone are associated with at least 3 inborn errors of metabolism including: Adrenal hyperplasia type 5, Corticosterone methyl oxidase I deficiency and Corticosterone methyl oxidase II deficiency.
