    Abstract: The present invention relates to an improved process for the production of sulfated hyaluronic acid (HA), sulfated HA-derivatives and/or mixtures thereof, having a high purity and a sulfation degree ranging from 1 to 3, which comprises the following steps: a) solubilization of HA-Na or HA-derivative-Na, in an aprotic solvent in the presence of an organic sulfonic acid; b) sulfation of the solution obtained by the addition of an excess of sulfating agents; c) precipitation in ethanol until a precipitate is obtained; d) solubilization of the precipitate thus obtained in a mixture of water and the aprotic solvent used in step a), in the presence of an excess of NaCl, with a pH adjustment within a range of 3 to 4; e) further precipitation with ethanol until a powder is obtained; f) washings of the powder coming from step e) and drying the product thus obtained under vacuum. The present invention also relates to sulfated HA, sulfated HA derivatives and/or mixtures thereof, having a high purity and sulfation degree ranging from 1 to 3, thus prepared, and the relative pharmaceutical mixtures.

    Abstract: The present invention relates to a process for the synthesis of conjugates of glycosaminoglycanes (GAG) with biologically active molecules of varying nature, comprising small molecules and macro-molecules. In particular, the present invention relates to the conjugation of hyaluronic acid (HA) and its derivatives with polypeptides and proteins with a biological action, such as, for example, interferons, erythropoietins, growth factors, insulin, cytokines, antibodies and hormones. An object of the present invention also relates to isolatable intermediates obtained by the partial or total reaction of GAG with protected amino aldehydes in the conjugation process mentioned above.

    Abstract: A process for the preparation of Rotigotine (I) and of pharmaceutically acceptable salts thereof, which comprises the reductive amination of an amine of formula 6 with the 2-thienylacetic acid- sodium boron hydride complex and which makes use of hydrobromide 5 as an intermediate (II) The process is advantageous from the industrial point of view in that it allows to obtain Rotigotine with high enantiomeric purity starting from optically active 5,6,7,8-tetrahydro-6-(S)-N-propylamino-l-methoxy- naphthalene (2), avoiding the use of dangerous reactives, the need for difficult chromatographic separation or the formation of by-products. Furthermore, two novel crystalline forms are disclosed.
