The effects of disalicylidenepropanediamine (DSPD) and disulfo-disalicylidenepropanediamine (sulfo-DSPD) on the photosynthetic electron transport of isolated chloroplasts have been reexamined.Our data suggest that DSPD, but not sulfo-DSPD, is an effective inhibitor of electron transport between photosystem II and photosystem I before or at plastocyanin. Furthermore, both DSPD and sulfo-DSPD block electron transport at the site of ferredoxin.Under certain conditions DSPD and even more so sulfo-DSPD function as autooxidizable electron acceptors.Finally it is shown that DSPD can cause an inhibition of photophosphorylation.According to our results the use of DSPD as a specific inhibitor of ferredoxin-dependent reactions has to be questioned.
我们重新研究了双水杨醛缩丙二胺（DSPD）和双磺基水杨醛缩丙二胺（sulfo-DSPD）对分离叶绿体光合电子传递的影响。我们的数据表明，DSPD 是一种有效的抑制剂，可在质体蓝素之前或与之同时抑制电子从 PSII 向 PSI 的传递，而 sulfo-DSPD 则不是。此外，DSPD 和 sulfo-DSPD 都能阻断铁氧还蛋白处的电子传递。在某些条件下，DSPD 甚至更像 sulfo-DSPD 一样作为自氧化电子受体。最后表明，DSPD 可以抑制光合磷酸化。根据我们的结果，DSPD 作为铁氧还蛋白依赖性反应的特异性抑制剂的使用需要受到质疑。
