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.
preferentially yield products of C-alkylation. Dipolar aprotic solvents favour O-alkylation; water favours C-alkylation. On the basis of these results procedures for the prepartion of 2-allyl-2-methyl-, 2-allyl-2-ethyl-, 2-methyl-2-propargyl- and 2 - benzyl - 2 - mehtyl - cyclopentane - 1,3 - dione have been developed. The alkylation of 2 - methyl - cyclopentane - 1,3 - dione with methyl bromoacetate was also
