A method of inhibiting the activity of Botulinum neurotoxin A metalloprotease which comprises contacting Botulinum neurotoxin A metalloprotease with at least one compound having the following structural formula:
- wherein
- n is 1 or 2;
- X1, X2, X3, X4, X5 and X6 are each independently N, S, O, SO2, CR7 or NR8 and at least one of X1 or X2 is N, S, O, SO2, or NR8;
- L is a linker which may be a direct bond or
- where Z is an optionally substituted alkyl, alkenyl, dialkenyl, trialkenyl, or aryl, or C(O)NH;
- and
- R1, R2, R3, R4, R5, R6 and R7 are each independently hydrogen, amino, amine with stabilized carbocations, carboxyl, optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl, alkoxy, aryoxy, cycloalkoxy, heteroaryloxy, alkoxycarbonyl, alkylamino, carbamoyl, alkylaminocarbonyl, alkylsulfhydryl, alkylhydroxymate;
- and
- R8 is hydrogen, OH, a halogen, or an optionally substituted alkyl.
