  (EN) The invention relates to the use of a compound of formula (I), wherein R1 and R2, independently of each other, represent hydrogen, hydroxy or lower alkoxy, or R1 and R2 together form lower alkylenedioxy; R3 is halogen, lower alkyl, halogen-substituted lower alkyl, hydroxy, phenyloxy, C3-C7-cycloalkyloxy or lower alkoxy; any R4 is, independently of R3 and independently of any other R4 if present, selected from halogen, lower alkyl, halogen-substituted lower alkyl, hydroxy, phenyloxy, C3-C7-cycloalkyloxy or lower alkoxy; X is oxygen, imino or (halogen-substituted or unsubstituted lower alkanoyl, [lower alkyl or carboxy-, lower alkoxycarbonyl-, aminocarbonyl-, N-mono- or N,N-di-lower alkylamino carbonyl]-lower alkyl; or C6-C12-aryl)-substituted imino; and n is 0, 1, 3 or 4; or a salt thereof if at least one salt-forming group is present, in the treatment of certain diseases and the inhibition of protein kinases, as well as to new compounds of formula (I) and salts thereof.(FR) Cette invention concerne l'utilisation d'un composé de formule (I) dans laquelle R1 et R2 représentent indépendamment l'un de l'autre hydrogène, hydroxy ou alcoxy inférieur, ou bien R1 et R2 forment ensemble alkylènedioxy inférieur; R3 représente halogène, alkyle inférieur, alkyle inférieur à substitution halogène, hydroxy, phényloxy, cycloalkyloxy C3-C7 alcoxy inférieur; tout R4 indépendamment de R3 et indépendamment de tout autre R4 existant est sélectionné parmi halogène, alkyle inférieur, alkyle inférieur à substitution halogène, hydroxy, phényloxy, cycloalkyloxy C3-C7 alcoxy inférieur; X représente oxygène, imino ou imino à substitution (alcanoyle inférieur à substitution halogène ou non substitué, [alkyle inférieur ou carboxy-, alcoxycarbonyle inférieur, aminocarbonyle, N-mono- ou N,N,di-alkylamino inférieur-carbonyle] alkyle inférieur; ou aryle C6-C12); et n représente 0, 1, 3 ou 4. On peut utiliser ce composé ou un de ses sels s'il existe au moins un groupe formant un sel, dans le traitement de certaines maladies et pour inhiber des protéine kinases. Cette invention concerne également de nouveaux composés de formule (I) ainsi que leurs sels.

  The present invention relates to a method for producing one or more low molecular weight aromatic lignin-derived compounds. The method preferably comprises providing lignocellulosic material, subjecting the lignocellulosic material to a pulping process, separating pulp to provide a substantially pulp-free process stream comprising a modified lignin-derived component, isolating the modified lignin-derived component, subjecting the isolated modified lignin-derived component to a decomposition step comprising oxidative cracking (cracking and oxidizing) or reducing under the influence of a catalyst or electro- oxidation, and subjecting the resulting products to an isolation step, to provide a low molecular weight aromatic lignin-derived compound. Said compound may be further modified, e.g. by annulation. The inventive method preferably comprises further oxidizing said compound to a redox active compound. Additionally, the present invention relates to compounds obtainable by the inventive method and to an assembly for carrying out the inventive method. Furthermore, the present invention refers to a method for providing an existing pulp and/or paper manufacturing plant with said assembly.
