Abstract

Following the recent identification of the naturally occurring 3-ylidene-4,5-dihydrophthalide ligustilide and its oxidation product dehydroligustilide as novel TRPA1 modulators, a series of seventeen 3-ylidenephthalides was synthesized and tested on TRPA1 and TRPM8 channels. Most of these compounds acted as strong modulators of the two channel types with EC50 and/or IC50 values distinctly lower than those of the reference compounds.
