A novel series of pyrrolidine derivatives as Na+ channel blockers was synthesized and evaluated for their inhibitory effects on neuronal Na+ channels. Structure–activity relationship (SAR) studies of a pyrrolidine analogue 2 led to the discovery of 5e as a potent Na+ channel blocker with a low inhibitory action against human ether-a-go-go-related gene (hERG) channels. Compound 5e showed remarkably
