Abstract: | The RM values of naphthols obtained in a chromatographic system where the stationary phase consisted of a silica gel G layer impregnated with silicone oil are much more closely related to the log P values in an octanol-water system than the RM values determined on polyamide layers. Similarly, the RM values of a series of acetophenones in the silicone system are closely related to their log P values. The equations describing the structure-activity relationship indicate the importance of lipophilic character and halogen substitution in determining the hemolytic activity and the acute toxicity of compounds. |
