Compounds, compositions and methods are provided which are useful in the treatment of diseases through the inhibition of sodium ion flux through voltage-gated sodium channels. More particularly, the invention provides substituted aryl sulfonamides, compositions comprising these compounds, as well as methods of using these compounds or compositions in the treatment of central or peripheral nervous system disorders, particularly pain and chronic pain by blocking sodium channels associated with the onset or recurrence of the indicated conditions. The compounds, compositions and methods of the present invention are of particular use for treating neuropathic or inflammatory pain by the inhibition of ion flux through a voltage-gated sodium channel.

Kinetic resolution of (+/-)-trans- and (+/-)-cis-2-phenylcyclopentanamine is effectively performed by lipase B from Candida antarctica, (CALB)-catalyzed aminolysis reaction. Whereas reaction between (+/-)-trans-2-phenylcyclopentanamine and ethyl acetate proceeds with a very high E value (>200) and conversion (50%), the corresponding acetylation of ()-cis-2-phenylcyclopentanamine happens with low E value (16) and conversion (28%). Nevertheless, this problem is overcome using other acyl donors such as (+/-)-1-phenylethyl and (+/-)-cis-2-phenylcyclopentyl methoxyacetates. The influence of the acyl donor on the CALB-catalyzed aminolysis of (+/-)-cis-2-phenylcyclopentanamine is also studied. (C) 2003 Elsevier Ltd. All rights reserved.
