[Thioacylamides and thioacylureas as inhibitors of photosystem II (author's transl)].
Thioacylureas and thioacylamides were found to inhibit photosynthetic O2-evolution (Hill-reactions) of "broken chloroplasts", some derivatives approaching an I50 of 10(-5) M. The inhibition site is near photosystem II. The inhibitory effects of the tested derivatives vary in theri pH-dependency between pH 5 and 8.
