Piper chaba

Decades of investigations in the natural products chemistry of the Piper genus yielded an important amount of monomeric and dimeric alkamides of diverse molecular architectures crnitributing to their biological activities [20-23,203,208-219]. Specifically, [4+2] dimers were isolated in P. chaba while [2 + 2] dimers were isolated in P. nigrum and P. longum, in both cases together with monomeric amides.
