TL;DR: The secondary metabolites isolated from Piper species for the period 1907 to June 1996 have been reviewed in this paper, where nearly six hundred chemical constituents belonging to different classes of bioactive compounds are listed together with their source(s) and references.
849 citations
TL;DR: The bioactive amides affinin and capsaicin isolated respectively from Heliopsis longipes roots and Capsicum spp fruits, were assayed for activity against Escherichia coli, Pseudomonas solanacearum, Bacillus subtilis and Saccharomyces cerevisicae suspension cultures and results are discussed in relation to previous reports concerning crude extract.

TL;DR: In this article, two new amides, aurantiamide and its acetate, were isolated from Piper aurantiacum and their structures were determined as N-(N′-benzoyl-S-phenylalaninyl)-S −phenyl-alaninol and S −phenyloninol, respectively, from chemical and spectroscopic studies.
50 citations
TL;DR: The structure of a 2,3,4 trisubstituted furanoid lignan, designated sylvone, was established as 1 from detailed spectroscopical and chemical studies as discussed by the authors.

TL;DR: An extensive compilation of structures of unsaturated amide products from Piper species (Piperaceae) with relevant literature references, and including a few representative examples of related compounds from other families, is presented in this article.
Abstract: An extensive compilation of structures of unsaturated amide products from Piper species (Piperaceae) with relevant literature references, and including a few representative examples of related compounds from other families, is presented. The biological activity attributed to Piper species, and many of the unsaturated amides they produce, includes organoleptic, medicinal and insecticidal effects and some of the more interesting biological properties are discussed in this chapter. Numerous synthetic approaches to the unsaturated amides have been developed, and a representative sampling of these strategies is presented.
