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. WebA limited series of compounds structurally related to phenytoin has been tested in the maximal electroshock seizure (MES) test in order to define the impact on their …

Phenytoin C15H12N2O2 - PubChem

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 ... WebSep 24, 2011 · Poupaert et al. observed that the anticonvulsant activity of phenytoin-like compounds was reduced when the hydrogen-bonding groups (CO and NH) were removed from the phenytoin structure. This study was supported by Cortes et al. [ 14 ] as they observed the loss of the activity with changing the hydantoin skeleton to imidazolone or ... WebIt was found that substitution of the imidazolidinone ring of phenytoin at position 3 by a chain containing a tertiary amine nitrogen atom changes the affinity profile from inactivated (pheny toin‐ like) to activated (quinidine‐like) cardiac sodium channels. The pharmacological activity of nine anti‐arrhythmic phenytoin derivatives was assessed in preventing … how zscaler improve the internet
