Since then however, those fatty acid moieties are also found in the Heliantheae tribe and other families: Rutaceae, Piperaceae, Aristolochiaceae and Menispermacea (AndradeNeto et al, 1996;Burden and Crombie, 1969;Greger et al, 1981;Greger and Werner, 1990;Saadali et al, 2001;Weenen et al, 1990b;Yasuda et al, 1981a). Nevertheless, the thiophene fatty acid moiety is a typical characteristic of Anthemideae, which was identified in e.g.…”

a b s t r a c tEthnopharmacological relevance: N-Alkylamides (NAAs) are a promising group of bioactive compounds, which are anticipated to act as important lead compounds for plant protection and biocidal products, functional food, cosmeceuticals and drugs in the next decennia. These molecules, currently found in more than 25 plant families and with a wide structural diversity, exert a variety of biologicalpharmacological effects and are of high ethnopharmacological importance. However, information is scattered in literature, with different, often unstandardized, pharmacological methodologies being used. Therefore, a comprehensive NAA database (acronym: Alkamid) was constructed to collect the available structural and functional NAA data, linked to their occurrence in plants (family, tribe, species, genus). Materials and methods: For loading information in the database, literature data was gathered over the period 1950-2010, by using several search engines. In order to represent the collected information about NAAs, the plants in which they occur and the functionalities for which they have been examined, a relational database is constructed and implemented on a MySQL back-end. Results: The database is supported by describing the NAA plant-, functional-and chemical-space. The chemical space includes a NAA classification, according to their fatty acid and amine structures. Conclusions: The Alkamid database (publicly available on the website http://alkamid.ugent.be/) is not only a central information point, but can also function as a useful tool to prioritize the NAA Q8 choice in the evaluation of their functionality, to perform data mining leading to quantitative structure-property relationships (QSPRs), functionality comparisons, clustering, plant biochemistry and taxonomic evaluations.

“…From different studies, it was suggested that the a,b-unsaturated carbonyl function rather than the N-isobutyl substituent is the responsible active site (Penali et al, 2007;Sittie et al, 1998;Weenen et al, 1990a). Longer, straight chain acid moieties and substituted (rather than primary) amines seem advantageous.…”

RESUMO:Neste trabalho foram avaliadas as atividades antinociceptiva e antiinfl amatória dos extratos das folhas de Zanthoxylum chiloperone. Os ensaios foram realizados pelos testes de contorções abdominais induzidas por ácido acético, tempo da lambida da pata induzida por formalina, edema de pata e pleurisia induzidas por carragenina, usando os extratos hexânico, em acetato de etila e etanólico administrados nas doses de 100 e 200 mg/kg. As doses testadas reduziram, signifi cativamente, as contorções abdominais, o tempo de lambida da pata, o edema de pata, o volume do exsudato e a migração leucocitária. Estes resultados sugerem que os extratos de Z. chiloperone possuem constituintes com atividades antinociceptiva e antiinfl amatória.Unitermos: Zanthoxylum chiloperone, atividade antinociceptiva, atividade antiinfl amatória.ABSTRACT: "Pharmacological activities of Zanthoxylum chiloperone (Rutaceae) extracts". In this work the antinociceptive and anti-infl ammatory activities of the extracts of leaves from Zanthoxylum chiloperone were evaluated. The tests were carried out by acetic acid writhing, formalin-induced paw licking, carrageenan-induced rat paw edema and pleurisy methods, using hexane, ethyl acetate and ethanol extracts administered in the doses of 100 and 200 mg/kg. The doses inhibited, signifi cantly, the contortions, the paw lick, the paw edema, the volume of the exsudate and the leukocytes migration. These results suggest that the extracts from Z. chiloperone possess constituents with antinociceptive and anti-infl ammatory activities.
