Isolation, Synthesis, and Evolutionary Ecology of Piper Amides
TL;DR: The phytochemistry of the genus Piper is rich in terms of numbers of compounds discovered, but given the diversity of this genus and the intraspecific diversity of secondary metabolites in those species that have been examined, Piper chemistry has not been adequately investigated.

Alkamides: a critical reconsideration of a multifunctional class of unsaturated fatty acid amides
TL;DR: Alkamides are natural products formed by connecting straight-chain, mostly unsaturated, aliphatic acids with various amines by an amide linkage as discussed by the authors and are known from eight plant families consisting of various combinations of 200 acids with 23 amines.

TL;DR: In this article, two unsaturated amides, retrofractamides A and C, were isolated from the total aboveground parts of Piper retroractum and were shown to be N -isobutyl-9(3′,4′-methylenedioxyphenyl)2 E,4 E,8 E -nonatrienamide from spectroscopic and chemical investigations.

Synthesis and characterization of all four isomers of methyl 2,4-decadienoate for an investigation of the pheromone components of Pityogenes chaicographus
TL;DR: Synthesis and characterisation of all 4 Isomers of Methyl 2,4-decadienoate for an Investigation of the Pheromone Components of Pityogenes-Chalcographus.

Structure Activity Studies on Aggregation Pheromone Components of Pityogenes-Chalcographus (Coleoptera, Scolytidae) - All Stereoisomers of Chalcogran and Methyl 2,4-Decadienoate
TL;DR: Attraction responses of walking beetles of both sexes were tested to mixtures of the synergistic pheromone components or analogs, and bioassays showed that theE,Z isomer of MD is the most active when tested with chalcogran, with no synergistic or inhibitory effects of the inactive isomers of MD.

Avijit Banerji,Sudhir C. Pal +1 more
TL;DR: Sylvamide, a new amide derivative, has been isolated from the petrol extract of the seeds of Piper sylvaticum (Roxb) from spectral and chemical properties as discussed by the authors.
