NOVEL ANTHRANILIC ACID DERIVATIVES AND CHLORIDE CHANNEL BLOCKING AGENT CONTAINING THE SAME

摘要

A chloride channel blocking agent containing anthranilic acid derivative is provided to show excellent validity and selectivity which result from excellent blocking activities of the anthranilic acid derivative. An anthranilic acid derivative is a compound having a structure represented by the formula I. In the formula I, R1 and R2 are independently selected from the group consisting of pentyl group, hexyl group, heptyl group, octyl group, decyl group, dodecyl group, tetradecyl group, hexadecyl group, cyclohexyl group, phenyl group, benzyl group, racemic-alphamethyl-benzyl group, chiral-alpha methyl-benzyl group, trifluoromethyl group, ethoxy group, butyloxy group, pentyloxy group, hexyloxy group, trifluoromethyloxy group and nitro group or two identical or different halogen atoms.
