Inhibition of coral and algal photosynthesis by ca-antagonist phenothiazine drugs.

Abstract

The effects of various calcium ion antagonists and ion transport inhibitors on photosynthetic O(2) evolution of corals, isolated zooxanthellae, sea anemone tentacles, and Chlorococcum oleofaciens were measured. Only the phenothiazine drugs were effective at inhibiting photosynthesis. Trifluoperazine, a calcium ion antagonist drug, inhibited at low concentrations, with 10(-4) molar and 8 x 10(-6) molar completely abolishing photosynthesis in the intact corals and isolated zooxanthellae, respectively. Net photosynthetic O(2) evolution of C. oleofaciens was eliminated by concentrations of trifluoperazine as low as 2.8 x 10(-5) molar.
