WebThe structure–activity relationship ( SAR) is the relationship between the chemical structure of a molecule and its biological activity. This idea was first presented by Crum-Brown and Fraser in 1865. [1] The analysis of SAR enables the determination of the chemical group responsible for evoking a target biological effect in the organism. WebThe relationship of the structure–antiarrhythmic activities of aporphines are summarized as: (1) C-1,C-2-methylenedioxy group on ring A of aporphines increases the planar configuration of molecules and plays an important role in both activity and toxicity; (2) a closed structure of the B ring is essential for both antiarrhythmic efficacy and ...
