Abstract:
The inhibitory activities (pI₅₀ values) of a series of 3-alkylamino-2-cyanoacrylic acid ester derivatives in relation to photosypthetic electron transport in isolated pea chloroplast suspensions are reported. Assuming such pI₅₀ values reflect the relative binding affinities for the inhibitor receptor site, the results suggest that several groups in these molecules interact specifically with the binding domain so that a multi-point attachment is formed. Stereochemical factors appear to play a significant role in the interaction.
