Binding Assay: In initial studies, we designed a set of molecules with branching at the nitrogen of the carbamate side chain as well as the carbon adjacent to the nitrogen. Two mutant channels were also constructed by site-directed mutagenesis. The β-STXo1 data points were collected to demonstrate that STX and its derivatives were oriented similarly within the channel pore. The similar reductions in affinity for STX to β-STXo1 and for cyclohexyl STX to cyclohexyl β-STXo1 provide strong initial evidence that the two molecules both reside in a similar orientation in the channel pore.
