Compounds relating to batrachotoxin are provided, in particular analogues that modulate the activity of sodium channels. Also provided are pharmaceutical compositions comprising compounds of the invention and a pharmaceutically acceptable carrier, including vehicles that modulate transdermal permeation of the compound. The subject compounds are useful in treatments, including treatments to reduce neuronal activity or to bring about muscular relaxation. The compounds also find use in the treatment of subjects suffering from a voltage-gated sodium channel-enhanced ailment or from pain. Further methods are provided for the preparation of the batrachotoxin-related compounds.

The Lewis acid mediated reaction of readily available 2-acetoxypropanal-N,N-dimethylhydrazone 1 with various open chain and cyclic silyl enol ethers 2 leads directly or via 4-oxoaldehyde-N,N-dimethylhydrazones 3 to N-(dimethylamino)-pyrroles 4. The subsequent reductive N-N bond cleavage provides an efficient and flexible method for the preparation of alkyl-aryl-di- and trisubstituted pyrroles 5.
