Patent

CA 2426613

A gelatinizer is provided having a component which promises to have biological compatibility, which can easily be mass-produced by a simple method, and which can solidify a large amount of water or aqueous solution when only a very small weight of it is used. This invention is a hydrogelatinizer represented by the general formula: R-A n where A, which may be identical or different, are respectively nucleotides, n is 2 or 3, and R is a hydrocarbon chain (when n is 2, R is bivalent, and when n is 3, R is trivalent), said hydrocarbon being bonded to a phosphoric acid part of said nucleotides.

La présente invention concerne des gélifiants comportant des constituants en matières biologiques dont on attend qu'ils soient biocompatibles. Ces gélifiants qui se prêtent à la production en masse, permettent de solidifier une grande quantité d'eau ou de solution aqueuse en cas d'utilisation en extrêmement petites quantités. En l'occurrence, les hydrogélifiants de l'invention sont représentés par la formule générale suivante: R-An. Dans cette formule, n vaut 2 ou 3. Les A, qui peuvent être identiques ou différents, représentent chacun un nucléotide. R représente une chaîne hydrocarbyle divalente (pour n = 2) ou une chaîne hydrocarbyle trivalente (pour n = 3). L'hydrocarbure est lié au fragment acide phosphorique du nucléotide.
