Abstract: The effects of 3-R2-2-[2-(6-R1-chromon-3-yl)ethenyl]benzothiazolium halides (CBH) on photosynthetic electron transport in spinach chloroplasts and in the algal suspension of Chlorella vulgaris were investigated. Using EPR spectroscopy it was confirmed that these compounds containing in their molecules two heterocyclic skeletons, namely bienzothiazole and chromone, interact with the intermediate D+, corresponding to the tyrosine radical TyrD situated in D2 protein on the donor side of photosystem 2. Consequently, higher concentrations of CBH inhibited oxygen evolution rate in Chlorella, vulgaris and the inhibitory effectiveness depended on the lipophilicity of the compound.
