Experimental autoimmune encephalomyelitis induction:

Mice used in each experiment were 8-12-wk-old female littermates. Experimental autoimmune encephalomyelitis (EAE) was induced by s.c. injection of mice (ve per group) with 100 mg myelin oligodendrocyte protein (MOG) peptides emulsied in CFA (Chondrex). Mice were also injected i.p. with 200 mg pertussis toxin (List Biological Laboratories) on days 0, 1, and 2.

SNAPtide Assay:

Inhibitory activity of small molecules from the compound libraries was determined by the decrease in BoNT/A LC enzymatic activity toward the SNAPtide uorogenic substrate (List Biological Laboratories). The assay was performed in 40 mM Hepes, pH 7.4, 0.01% Tween-20 at room temperature (22 C). In dose response IC50 assays, 9 point 1:3 dilutions of compounds in DMSO (1 L) were preincubated with 10 L of 70 nM BoNT/A LC (expressed in Escherichia coli and puried as described elsewhere22) in 79L of 40 mM Hepes buer in a 96-well black plate (Greiner) for 5 min at room temperature…
