Piperine, the pungent alkaloid of black pepper, and several of its derivatives are modulators of γ-amino butyric acid type A (GABAA) receptors. Concomitantly, this natural product has also been reported to activate transient receptor potential vanilloid type 1 (TRPV1) receptors. We have developed a Heck cross-coupling reaction of conjugated dienamides enabling the rapid assembly of piperine derivatives containing a modified aromatic core. Upon assessment of a focussed compound library, key aromatic substituents were identified selectively affecting either the GABAA or the TRPV1 receptor.
