摘要:
The present invention relates to an extract of Salix spp obtainable by fractioning on a resin and to the process for its preparation.The extract of the invention is characterized by an high content in salicin derivatives, reduced content in high molecular tannins and a content in proanthocyanidins sufficient to inhibit some tissue metal proteases. The product is formulated in oils rich in ω-3 and ω-6 acids which provide a better absorption of the extract active principles, also increasing synergetically their action.

摘要:
Disclosed is a series of N-deacetylthiocolchicine derivatives of formula I in which: the linker is a bivalent straight or branched C1-C8 alkyl residue, C3-C8 cycloalkyl, a phenylene or heterocyclic C4-C6 ring; the G1 and G2 junctions, which can be the same or different, are —CO—, —CONH—, —CR2— groups in which R2 is hydrogen or a straight C1-C4 alkyl residue, or the G1-linker-G2 group is the —CO— group. The compounds of formula I have antiproliferative, antinflammatory, antiarthritic and antiviral activity.
