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.
测定了各种钙离子拮抗剂和离子转运抑制剂对珊瑚、分离的虫黄藻、海葵触手和绿球藻光合 O2 演化的影响。只有吩噻嗪类药物对光合作用有抑制作用。三氟拉嗪是一种钙离子拮抗剂药物,在低浓度下抑制,在完整珊瑚和分离虫黄藻中,分别为 10(-4)摩尔和 8 x 10(-6)摩尔完全消除光合作用。三氟拉嗪的浓度低至 2.8 x 10(-5)摩尔就可消除绿球藻的净光合 O2 演化。
