ORGANIC DERIVATIVE OF A METAL WITH A PHOSPHOLIPID STRUCTURE, USE OF THIS DERIVATIVE AS A BIOMEDIATOR, PROCESS FOR ISOLATING THIS DERIVATIVE AND PHARMACEUTICAL COMPOSITIONS CONTAINING IT

摘要

The invention relates to a new organic derivative of a metal. This organic derivative of a metal is characterized in that it consists of a derivative of a metal, preferably of valency equal to at least 3, with an organic compound comprising a phospholipid conferring watersolubility or water-miscibility on the organic derivative of said metal. Advantageously, this phospholipid comprising ¢sic! at least one unsaturated fatty acid of the ?-linolenic or .gamma.-linolenic acid type. The organic derivatives of a metal according to the invention constitute valuable biomediators, and accordingly constitute active principles of pharmaceutical compositions having various activities, and in particular immunomodulatory activity.
