【Abstract】 D\|Quantitative Structure—Activity Relationships of a series of cyanoacrylate inhibitors which are known to act by blocking photosynthetic electron transport close to photosystem II reaction center in the thylakoid membranes of plant chloroplasts have been investigated using comparative molecular field analysis(CoMFA). The active conformations of the title compounds were obtained by constrained systematic search program. The resulting CoMFA model with considerable predictive ability shows that the contribution of steric effects for activities of cyanoacrylate inhibitors is more important than electrostatic effects.更多还原
