Fig. 7From: Development of models for predicting Torsade de Pointes cardiac arrhythmias using perceptron neural networksMost significant features identified by SDAR technique. The structure on the left shows a benzene ring and nitrogen atom with a distance of 7–8 Å (approximately equal to a sequential four-atom distance). The middle structure shows a phenylmethanamine fragment joined with a dimethylethanamine portion. On the right is 4-(diphenylmethyl)-piperidineBack to article page
