Title
(EN) MODIFIED POLYUNSATURATED FATTY ACIDS
(FR) ACIDES GRAS POLYINSATURES MODIFIES
Abstract
(EN)
The present invention provides polyunsaturated fatty acid compounds having antimalarial and/or neutrophil stimulatory activity. The polyunsaturated fatty acids contain 18-25 carbons and 1-6 double bonds and are characterized in that they have one or two substitutions selected from the group consisting of $g(b) oxa, $g(g) oxa, $g(b) thia and $g(g) thia. It is also preferred that the polyunsaturated fatty acid compound includes a further substitution selected from the group consisting of hydroxy, hydroperoxy, peroxy, carboxymethyl substitutions or attached to an amino acid. The invention also provides a method of producing an unsaturated oxa substituted fatty acid comprising reacting an unsaturated fatty acid alcohol with a carbene that is inserted in the OH bond of the alcohol. The invention further provides a method of treating inflammation with a composition comprising at least one hydroxy, hydroperoxy or peroxy derivative of a polyunsaturated fatty acid having a C18-24 carbon chain and 1-6 cis or trans double bonds.
(FR)
La présente invention concerne des composés d'un acide gras polyinsaturé ayant une action antipaludéenne et/ou stimulante des neutrophiles. Les acides gras polyinsaturés, qui contiennent entre 18 et 25 atomes de carbone et une à six liaisons doubles, se caractérisent par le fait qu'ils ont un ou deux substituants sélectionnés à partir du groupe formé de $g(b) oxa, $g(g) oxa, $g(b) thia et $g(g) thia. Il est préférable que le composé d'acide gras polyinsaturé comprenne un substituant supplémentaire sélectionné à partir du groupe formé des susbstituants hydroxy, hydroperoxy, peroxy ou carboxyméthyl ou attaché à un acide aminé. L'invention porte également sur un procédé de production d'un acide gras insaturé substitué par oxa et qui consiste à faire réagir un alcool gras insaturé avec un carbène inséré dans la liaison OH de l'alcool. Cette invention présente, de surcroît, une technique de traitement anti-inflammatoire sous la forme d'une composition comprenant au moins un dérivé hydroxy, hydropéroxy ou péroxy d'un acide gras polyinsaturé ayant une chaîne carbonée C18-24 et une à six liaisons doubles cis ou trans.
