Abstract
Prochlorperazine, a phenothiazine antiemetic, has been reported to protect rats against mercuric chloride (HgCl/sub 2/)-induced nephrotoxicity. Mercuric ion and 12 other divalent metal ions of toxicologic importance inhibit the activity of calmodulin, a ubiquitous intracellular calcium receptor and regulatory protein, at physiologically relevant concentrations. Phenothiazines, including prochlorperazine, are reversible calmodulin antagonists, and as such they interact with divalent calcium at the level of calmodulin. It was of interest therefore to evaluate the comparative effects of several phenothiazines on HgCl/sub 2/-induced nephrotoxicity in rats.
